Introduction:

Indian Railways is the biggest railway network in the world. Indian Railways cater millions of commuters and long-distance passengers daily. A reliable & safe electrical system in signaling & inside coaches ensures safe and efficient operation of trains and passengers’ safety. The shoulders of Indian Railways are entrusted with the safety & security of thousands of passengers who travel with it daily. A minor malfunction in the signaling system or in electrical facilities inside the coaches like lights, fans, mobile charging points, chilling systems, because of earth leakage/fault can cause a catastrophe which is unimaginable, leading to loss of life of thousands.

Indian railway has recently launched its premium/ high-speed rail operations on selective routes and Bullet Train is also in the pipeline -to be introduced in near future. All these initiatives necessitate a thorough upgradation of existing Indian railway infrastructure. For such reasons new technologies and the latest version of measuring, monitoring and control systems will be required. Automated On-line continuous monitoring of various distribution circuits in the signaling system and coaches is required which will strategically increase the throughput and safety of trains. Such arrangements would ensure that the faulty circuits are detected, located and corrected within an hour without the need of shutting down the electrical power distribution system.

Ungrounded power supplies have the advantage of avoidance of shock & fire and ensure continuity of power to loads in the event of first ground fault. To get the above benefits IEC 60364-4-41 recommends providing an on-line insulation monitoring device to monitor & indicate the first ground fault. Further the first ground fault should be eliminated within the shortest practicable time. Therefore, to identify the faulty feeder as fast as possible and to support the maintenance staff, an online fault location system should be implemented in a large complex distribution system. Further the measurement and monitoring technology shall be reliable and accurate built with state of the art technology in the presence of AC, DC and AC/DC loads and various electrical noises. Therefore the measuring and monitoring system shall be in conformance to prevalent International standards for operation in the industrial environment. Online insulation monitoring shall conform to IEC 61557-8 and online fault location up to feeder level shall conform to IEC 61557-9. Further the system shall be qualified as per IEC 61326 for EMI/EMC.

Grounded distribution systems are also utilized in various non-critical and auxiliary electrical power distribution systems in railways. Grounded AC, DC & AC/DC distribution systems are used. Rather than waiting for short circuit and catastrophic failures a leakage current monitoring system to monitor the leakage currents due to failure of insulation for advance leakage information shall be provided. Again for using the monitoring system in industrial environment the solution shall be in conformance to IEC 62020

Reference Standards:

11. IEC 62020-1 : Electrical accessories – Residual current monitors (RCMs) – Part 1: RCMs for household and similar uses

Solution for signaling system:

Similar to British and European Railways, Indian Railway signaling systems utilize various types of ungrounded low voltage power supplies like 110 V AC/DC, 60 V AC/DC and 24 V AC/DC for the various signal & switching circuits. The circuits include Track Point Switches, Track Motors, Signal Control Relays and Signaling Lamps. The design generally conforms to national and international standards. Most of the cables associated with the above-mentioned circuits are outdoor and run along railway tracks either buried or over ground. They are exposed to the harsh weather and unfavorable environment. These affect

their insulation resistance and are subject to deterioration in the harsh environment over a period. This leads to mal-operation and unreliable operation of signal systems, putting the life of thousands of commuters at stake. US, British and European in-house railway standards recommend continuous monitoring of the insulation resistance of these circuits to ensure reliable and safe movement of trains. Further to detect the individual faulty feeder an online fault location system shall be provided.

Each galvanically isolated separate supply source will consist of an online insulation monitor connected near to the source main bus. Individual feeders will be installed with special highly sensitive sensors over the complete feeder wires along with multichannel earth fault detectors to which the sensors shall be connected for identifying automatically the faulty feeder without shutting down the distribution system. After identifying the faulty feeder, with the help of a portable handheld fault locator exact location of earth fault can be identified. Portable devices also trace the signal injected by the insulation monitoring device.

A typical sketch of the solution is shown below.

Solution for Railway Coaches:

An ungrounded power supply is also used inside coaches’ electrical systems to have some benefits like:

a) Prevents fire due to insulation leakage.

b) Prevents fatal electrical shock to the passengers.

c) Availability of loads

The main incomer power supply to individual coaches is either 800 V 3 phases 3 wire ungrounded or 800 V 3 phase 4 wire grounded system depending on the design requirement of RDSO. Which is later being stepped down to 415V 3 phase, 230 & 110V single phase as per the load requirement inside the coaches. Each and every relay should have MODBUS RTU communication system to directly communicate with HMI system

Each galvanically isolated separate supply source will consist of an online insulation monitor connected near to the source main bus. It will measure the insulation resistance of the complete connected distribution system up to individual loads and provides alarm whenever the earth fault insulation resistance is below set limits. The maintenance staff can plan for fault identification and repair.

Portable handheld fault evaluator suitable up to 800V AC system can be used to localize faults during running condition of the train or at loco shed.

A typical sketch of the solution is shown below.

Electrical safety in Railway Tunnels:

Train routes in mountainous landscapes lead across a sequence of tunnels and bridges. To ensure passenger safety and efficient incident response, our route operations plan must prioritize preparedness for tunnel emergencies. Along the route, fire brigades and Technical Relief Services must be equipped for assistance in case of a catastrophe. Additionally, To support the rescue concept, hydrants and emergency power supply points must be installed in the tunnels. Rescue teams thus can have quicker access to water and electrical energy in sufficient quantities. According to the guideline 95401, in Germany the power supply has to be designed as an ungrounded system.

Securing a functioning power supply for rescue teams even in case of catastrophe: This allows rescue teams to rely on a functioning power supply in the event of a catastrophe, continuous insulation monitoring is required. Critical installation conditions are reported to the supervising system in a timely manner.

Fast localisation of insulation faults: Even in the case of extensive routes, insulation faults can be allocated to the individual tunnel sections when using insulation fault location systems such as signaling systems. A further advantage is that they find insulation faults during ongoing operations, without cable disconnection.

Case study

1. Bender offered Solution in Signaling System:

BENDER, the world leader in this technology provides universal and customized solutions in on-line monitoring insulation resistance and fault location in ungrounded AC & DC electrical systems. Suitable for signaling systems.

BENDER with its large amount of experience and R&D efforts over more than 70 years provides ingenious solution for on-line insulation monitoring and fault location up to individual feeder level in AC/DC systems in the presence of various industrial electrical noises without spurious operation and indications (EMI/EMC qualified). Bender Insulation Monitoring Device conforms to IEC 61557-8, Fault location system conforms to IEC 61557-9 and EMC qualifies as per IEC 61326. The implementation schematic in Indian Railway Signaling is below:

As shown in the figure above, the insulation monitoring scheme for ungrounded systems consists of Insulation Monitor ISO 685 connected to the main ungrounded distribution source bus. The insulation monitor may derive its power from the same system and it can accept a wide range of power input from both AC & DC from 0 to 600 Volts. The insulation monitor injects a special Bender patented bi-directional signal into the system with respect to earth and will on-line monitor the insulation of the complete ungrounded distribution system of all feeders including loads supplied from same source with respect to earth and indicate the value in the range of 1 Kohm – 10 Mohm. It will generate an alarm in case the insulation of the complete distribution system falls below the set value. Typical set value for the alarm can range between 50 to 100 ohms/ Volt of the system voltage and it can have another unique feature that allows it to generate two different alarms indicating gradual degradation of insulation resistance.

We can define the 1st alarm as a pre-alarm and the 2nd one as a critical alarm. For safe running of the system one can set the pre-alarm value at 200 ohm/Volt and critical alarm value at 100 ohm /volt which is in line with IEC (e.g. for system voltage 110 V, the pre-alarm setting is 40 Kohm and critical alarm is 20Kohm). The Operation & Maintenance staff will get to know of the insulation fault in advance owing to the indication of the pre-alarm and further plan the maintenance activity as per their convenience and resource availability.

The main power supply is distributed into various feeders as per the requirement of the station signaling system. To locate the actual faulty feeders, each of the load feeders will be installed with specialized highly sensitive Bender patented core balance Current Transformers (CT), with sensitivity of 5 mA. All CT’s will be connected to required nos. of 12 channel evaluators EDS440. The EDS440 may draw its power from the main distribution system. In case of insulation fault (lower than both the alarm settings) in any feeder , the ISO 685 will first produce a visual alarm followed by injecting a test current (adjustable by user) in the distribution system with peak value limited to 25 mA.

The peak value of 25 mA is much below the dropout current of 40 mA of relays used in railway signal circuits thus, won’t interfere with the functioning of the system. This test current will pass through the faulty feeder via earth and the corresponding faulty feeder CT will detect and indicate on-line the fault in the corresponding channel of EDS440. ISO 685 & EDS-440 are also interconnected with 2-wire RS 485 interface hence ISO 685 will also indicate the channel number of the faulty feeder. Further with the help of Bender make portable fault evaluator EDS 3090 identification of the exact faulty component also possible. A Bender make gateway may also be used to indicate the faulty feeder in the control room on a PC.

In this way the complete system will be monitored online 24X7, Which is very much required for the railway signaling system.

Situated on the east bank of the Hooghly River, sprawling across 206.08 square kilometers, Kolkata rules as the crown jewel of West Bengal. This bustling metropolis, exceeding 15 million residents, pulsates with a vibrant informal sector employing over 40% of its workforce. A melting pot of diverse backgrounds and occupations, Kolkata, according to the 2011 census, embraces a population of 4,486,679.

Occupying a pivotal position, Kolkata acts as a magnet, attracting a multitude from the northeast and surrounding regions. In the grand canvas of Indian geography, it occupies a place of prominence, being one of the most developed urban centers amongst the seven sister states, Sikkim, and Bihar. Kolkata carries the torch of art and literature, upholding Bengal’s legacy as the land of enlightenment.

The scenario of urban mobility paints a picture of burgeoning growth. Vehicle registration has witnessed a staggering 44% increase over the past seven years. Delving into Kolkata’s historical accounts, we find it was the sole city graced with a tram service, operated by the Calcutta Tramways Company. As of 2023, six tram routes diligently serve the city. A robust bus system, a harmonious blend of government and private ownership, keeps Kolkata on the move. Five long-distance railway stations, alongside the metro system – the first of its kind in India – further bolster connectivity.

In conclusion, Kolkata’s urban mobility landscape presents a fascinating account woven with threads of growth and facilitation. Buses, trams, personal vehicles, commuter rails, and the metro – all these elements work in concert to channel the city’s aspirations towards a thriving future. This intricate network strives to create a perpetually evolving urban haven, a livable space for its residents and those drawn to its magnetic charm.

Now, we delve deeper, embarking on a voyage to explore the intricacies of the metro system’s various constituents and extensions. From lines to locations, sustainability to attractiveness, we shall gain a comprehensive understanding of this vital rail-based rapid transit system that keeps the heart of Kolkata beating.

Let’s delve deeper into it.

Kolkata Metro

Weaving its way through the vibrant city of Kolkata, the Kolkata Metro is a speedy transit system that keeps the city moving. Unveiled in 1984, it holds the distinction of being the first metro to zip around India, and remains one of the busiest with over 700,000 daily riders! Owned and operated by a tag team of Metro Railway, Kolkata and Kolkata Metro Rail Corporation, it’s the only metro system in the country to run under the control of Indian Railways.

The Kolkata Metro story began in 1972, with work starting on Line 1. It wasn’t all completed at once though. In October 1984, the first little piece, a 3.4 kilometer stretch between Esplanade and Netaji Bhavan stations, opened its doors. Over the next ten years, they kept building, adding more sections until Line 1 reached a cool 16.45 kilometers long by 1995.

Early Dreams

The seeds for the Kolkata Metro were sown much earlier than its groundbreaking. Intriguingly, the concept can be traced back to 1919 when a committee, set up by W. E. Crum during the Imperial Legislative Council session at Shimla, proposed a metro line for Calcutta (now Kolkata). This visionary plan aimed to connect Bagmari in the east to Benaras Road, Salkia, in Howrah on the west, with a daring passage – a tunnel beneath the Hooghly River! However, the estimated cost of ₹36.4 crore in 1919 proved to be a significant hurdle.

Just two years later, in 1921, renowned engineer Harley Dalrymple-Hay, known for his work on London’s underground railways, proposed a similar east-west metro connection for Kolkata, christened the “East-West Tube Railway.” Unfortunately, this proposal too couldn’t garner the necessary funding and remained unrealized in 1923.

These early proposals, though unfulfilled, showcase the foresight and planning that went into envisioning Kolkata’s future public transport needs. They paved the way for the collaborative efforts that eventually brought the metro to life decades later.

Early Collaboration and Planning

The inception of the Kolkata Metro can be traced back to the visionary efforts of then Chief Minister of West Bengal, Bidhan Chandra Roy, who reconceived the idea of an underground railway for Kolkata as early as 1949. However, concrete progress eluded the project until the early 1970s.

In 1969, recognizing the pressing need for an efficient mass transit system in Kolkata, the Metropolitan Transport Project (MTP) was established. This marked a significant step towards addressing the city’s burgeoning traffic woes. Collaborating with foreign expertise, the MTP sought solutions to Kolkata’s transportation challenges.

A team of French experts conducted an initial survey, but tangible outcomes were elusive. It wasn’t until the MTP engaged Soviet specialists from Lenmetroproekt and East German engineers that substantive progress was made. In 1971, a comprehensive master plan was devised, outlining the construction of five rapid-transit (metro) lines spanning a total length of 97.5 km (60.6 mi).

From this plan, three priority lines emerged:

1. Dum Dum – Tollygunge (Line 1, presently operating from Dakshineswar to New Garia)
2. Bidhannagar – Ramrajatala (Line 2, presently truncated until Howrah Maidan)
3. Dakshineswar – Thakurpukur (Divided into Line 1; Noapara to Dakshineswar and Line 3; Joka to Esplanade)

Given the pressing demand and the crucial north–south corridor’s significance, the Dum Dum to Tollygunge stretch, covering 16.45 km (10.22 mi), was accorded the highest priority. On 1st June 1972, construction work for this pivotal segment was officially sanctioned, heralding the beginning of Kolkata’s journey towards establishing its iconic metro system.

The Purple Line sees around 2,000 people daily, being operational from January 2, 2023.

Challenges faced by Kolkata Metro

1. Ownership and Decision-making: Unlike the autonomous structure of Delhi Metro, Kolkata Metro is owned and operated by Indian Railways. This centralized control often leads to delays and limitations in decision-making, as every aspect, from funding to route realignment, relies solely on Indian Railways.

2. Construction Challenges: In densely populated areas, the absence of free spaces for elevated tracks necessitates the construction of underground systems. However, the construction of underground metro tunnels, as seen in the Bowbazar area, has resulted in structural damages to nearby homes, leading to evacuation and significant project delays.

3. Technical Limitations: Kolkata Metro’s construction in the 1970s introduced technical limitations, such as tunnel dimensions and reliance on Indian Railways infrastructure. The use of Indian meter gauge shells mounted on broad gauge bogies for rolling stock necessitates custom-built rakes, resulting in additional costs and limited options for manufacturers. Additionally, the use of Indian Railways signaling instead of European signaling has contributed to operational snags, delays, and safety concerns.

Introduction

Imagine your travel time getting cut-off by 50% with a bonus of traveling seamlessly and punctually. Yes, you read it right. That’s the USP of the metros in India today that they not only cut-off your travel time but also make ‌traveling seamless and punctual with its rapid lines providing public an unwavering and unparalleled service. Nagpur Metro is nowhere behind in this rapidly running urban transit landscape which is in-turn the driver of growth and development. In this very sequence of development, one major aspect at global as well as national level is sustainable development.

As per the annual reports of Maharashtra Pollution Control Board (MPCB), Nagpur has witnessed a tremendous improvement in its air quality index especially in the PM₁₀ content in its air. Not only the functioning & operations of the Nagpur Metro are unique and future-friendly but even the pre-operational catharsis ranging from planning, monitoring and constructing all were done in a unique and future-oriented model. It holds the title of completing the entire project in record time of 27 months or 2 years & 3 months.

Nagpur, a city consistently lauded for its green spaces, top-ranked public transport, and excellent healthcare, offers an alluring blend of livability and progress. This vibrancy extends to its revered Deekshabhoomi pilgrimage site, home to the world’s largest Buddhist stupa. Now, the Nagpur Metro adds another layer to the city’s allure, revolutionizing urban mobility with headquarter of companies like Haldiram, Vico, Dinshaws & also the prominent technology companies like TCS, Tech Mahindra Infosys, LTI Mindtree, Accenture and many more.

India’s marriage with urban mobility still remains a tightrope walk as we navigate our journey to be in the Top 5 economies of the world. Urban Mobility is an all-encompassing term taking in its loop things from Economic Development to Connectivity & Cultural Integration to Tourism Hotspot. With cities expanding their boundaries beyond, there is a strong need to promote rail based transportation systems into their sprawling geography that promise a punctual, seamless & dedicated public service to sustain the pace that new urban centers demand.

Let’s delve in the journey of a not so normal yet punctual & record-holder metro system of India.

Inception

The story begins with its conceptualisation in the year 2012, when the government of India decided to equip cities having population more than 20 Lakh with metro rail system. This made Nagpur too eligible for a metro railway system. The then Union minister for urban development, Kamal Nath, proposed a metro rail in Nagpur and also instructed the authorities to carry the project further with DPR preparation which was further entrusted to Delhi Metro Rail Corporation (DMRC) in the February 2012 itself with a budget allocation of ₹2.4 crore (equivalent to ₹4.5 crore) from the central ministry.

Further a Special Purpose Vehicle (SPV) named Nagpur Metro Rail Corporation (NMRC) today known as Maharashtra Metro Rail Corporation Limited (MAHA-METRO) came to life with the Government of India & Government of Maharashtra having 50:50 equity. It is the body entrusted with timely completion and successful execution of the project.

DPR & Approval

As the DPR went to DMRC, two routes namely, Automotive square, Kamptee to MIHAN Metro depot and Prajapati Nagar, East Wardhaman Nagar to Lokmanya Nagar, Hingna with 17 stations & 19 stations at an estimated cost of ₹8,680 crore (US$1.1 billion). The length of the metro went initially from 30 Km to 42 Km in July 2012.

Further, to comply with the norms of financial metrics as suggested by the then central government, precisely to keep the IRR above 8%, a realignment of the metro routes in the DPR was proposed. The original alignment of Corridor-I proposed was passing through Khamla Road, Airport Area after Sahakar Nagar before ending at MIHAN.

To avoid extra costs & extra time into property acquisition for the original alignment, the alignment was re-calibrated to reach the Wardha Road only without going on Khamla Road. In the realignment it was decided that the North-South Corridor of the Nagpur Metro will pass through Wardha Road after Congress Nagar Metro Station. To cut down more on costs the underground alignment was also dealt away with and it was decided that after crossing existing intersection point of Wardha Road & Airport Road, the alignment will be shifted to the MIHAN area and alignment in this portion would be at grade running parallel to Wardha Road up to ROB and parallel to railway line thereafter up-to proposed Car Depot.

After long revisions and realignments, the project DPR was finally submitted in November 2013. It was further approved by the central cabinet in August 2014.

While the state government has already approved, the phase 2 of the project at an estimated cost of Rs 6,708 crore.but the DPR for the same lies with the central government with pending approval. The foundation stone for the project has already been laid by the Prime Minister on December 11, 2022.

Construction & Planning.

This way the construction of Nagpur Metro’s Phase 1, a 38.215 kilometer project featuring both elevated and at-grade sections, began in 2015 with the Nagpur Metro authorities employing best-in-class planning & monitoring mechanism in order to achieve the benchmark of best quality work done among all the metro projects in India.

The Nagpur Metro Rail project, with its over 20 major contractors, 30 subsystems, and vast scale, presented a significant management challenge. Timely completion and quality assurance (including 7 tests) were paramount concerns. To address these complexities, Nagpur Metro Rail Corporation Limited (NMRCL) adopted a digital project management approach from the outset. This decision aimed to improve project information flow, minimize cost and schedule overruns, and ensure successful project delivery.

Weekly and quarterly data analysis enabled NMRCL to leverage model-based delay analysis. This provided management with a comprehensive, real-time picture of the project, facilitating efficient decision-making.

Benefits of Model-Based Delay Analysis:

Integrated Project View: Linked the 3D model, schedule, and cost for a holistic project understanding.
Proactive Flaw Detection: Enabled timely rectification of construction sequencing flaws by simulating the schedule with the 3D-model.
Real-Time Progress Monitoring: Facilitated model-based monitoring of construction progress during execution.

Connectivity Through Lines

Connectivity is the key element that defines the cities today. More connectivity translates into more business, more exchange, more integration and most importantly more convenience into the thick and thin of transportation across the city.

Pre-Metro Scenario – A crowded Canvas

Nagpur’s transportation landscape, prior to the metro’s arrival, presented a complex picture with three distinct categories:

Public Transport: This included:
- Mini City Buses (seating 20)
- Large State Transport Buses (seating 50)
- Chartered Buses used by schools and offices
- Buses from neighboring states

This system, while offering various options, often faced limitations.

Intermediate Public Transport (IPT): Dominated by auto-rickshaws, IPT served as a crucial mode of transport despite being a bit more expensive.
Private Vehicles: This category encompassed bicycles, two-wheelers, and cars of all sizes.

A Chaotic Network: The presence of such a diverse range of vehicles vying for limited space on the roads created a congested environment. Traffic intersections were particularly notorious for gridlock. With minimal space between vehicles, average speeds remained a slow 15-20 kilometers per hour. This scenario translated into longer travel times, frustration for commuters, and a strain on the city’s infrastructure.

Some Failed Initiatives: Nagpur’s Pre-Metro Mobility Struggles

Prior to the metro’s arrival, Nagpur authorities grappled with the challenge of improving urban mobility. One such attempt involved subsidizing public bus fares to entice ridership. However, this strategy failed to attract higher and middle-income groups who prioritized speed over cost. Public buses simply couldn’t compete with the convenience of private vehicles.

Another initiative, the Bus Rapid Transit (BRT) system, aimed to create dedicated lanes for public buses, theoretically expediting travel times. However, the implementation lacked the finesse needed to seamlessly integrate the BRT system with the existing public transport network. This resulted in a disjointed user experience, failing to achieve the desired synergy between commuters and the public transport system. Consequently, the objective of achieving an optimal distribution of transportation modes (mode share) remained an elusive dream.

Post- Metro Scenario

Nagpur Metro’s Phase 2 is more than just an extension; it’s a bridge connecting people, places, and opportunities. This exciting expansion will reach a population of over 1 million residing in key areas surrounding Nagpur.

Satellite Cities: Phase 2 stretches its reach to satellite cities like:
- Kapsi: A major transport hub, Kapsi will benefit from a direct connection to Nagpur, improving movement of goods and people.
- Hingna: This rapidly developing town will see a surge in accessibility, attracting residents and businesses alike.
Industrial Powerhouses: The expansion connects to:
- Butibori: The district’s largest industrial estate, Butibori, will witness a significant improvement in worker commutes. Thousands employed in the 750+ units can look forward to a faster and more reliable travel option.
- Hingna: Home to its own industries, Hingna will benefit from a dual advantage – a connected workforce and enhanced business opportunities.
Mining Marvels: The Kanhan route passes through Kamptee, a significant town with residents who frequently travel to Nagpur for work and education. The metro will significantly reduce travel times, making commutes a breeze.

With a total length of 82 km upon completion, Nagpur Metro Phase 2 paints a brighter picture of connectivity, promising a faster, more efficient, and more accessible future for the city and its residents.

Ridership Figures of Nagpur Metro

Nagpur Metro has witnessed a positive trend in ridership. In February, daily ridership surpassed 93,000 passengers, a significant increase. However, this number remains below the level needed for the project to break even.

Prior to the pandemic, ridership even crossed the 1 lakh mark, but it dipped after fare hikes implemented for revenue rationalization.Despite the ridership growth, Nagpur Metro’s first phase still incurs losses. Even after considering non-fare revenue streams, the average monthly loss stands at ₹3.5 crore.

Nagpur Metro: A Marvel of Sustainability

Nagpur Metro isn’t just revolutionizing urban mobility; it’s also spearheading a movement towards a greener future for the city. Here’s how:

Reduced Emissions: Data from Hingna Road, served by Lokmanya Nagar and Bansi Nagar stations, showcases a significant decrease in air pollutant levels since the metro’s inception. Nitrogen Oxide (NOx) emissions have dropped steadily, from 41 in 2019 to 23.43 in 2021. Similarly, Sulphur Dioxide (SO2) levels have dipped from 14 in 2019 to 8.38 in 2021.
Combating Congestion: By offering a fast, reliable alternative to private vehicles, the metro reduces traffic congestion, a major contributor to air pollution. While vehicle registration in Nagpur has increased by 20% in 2022, the metro helps manage this growth by encouraging a shift towards public transport.
Improved Last-Mile Connectivity: Recognizing the importance of seamless last-mile connectivity, authorities have initiated shared auto services at Kasturchand Park and a shuttle bus service linking the airport with the Airport Metro Station. These efforts ensure a smooth transition between metro travel and reaching final destinations.

Challenges Faced by Nagpur Metro

Based on the information provided, here are some of the key challenges faced by the Nagpur Metro:

Financial Sustainability: While ridership is increasing, it hasn’t yet reached the break-even point. This means the metro incurs monthly losses despite non-fare revenue streams.
Last-Mile Connectivity: While initial efforts have been made with shared autos and shuttle services, a more comprehensive feeder network is needed to effectively connect metro stations with surrounding areas. This will encourage more people to use the metro for their entire journey, not just part of it.
Fare Optimization: The balance between attracting ridership and generating revenue through fares needs to be addressed. Fare hikes implemented for revenue rationalization may have deterred some potential riders, particularly those who are cost-conscious.

Competition from Private Vehicles: The convenience of private vehicles remains a challenge, especially for short trips.

Public Awareness: Encouraging a modal shift towards public transport requires ongoing public awareness campaigns highlighting the benefits of the metro, such as reduced travel times and environmental advantages.

Overall, Nagpur Metro faces the challenge of balancing ridership, revenue generation, and service optimization to achieve long-term financial sustainability and become the preferred mode of public transport for Nagpur residents.

Conclusion

Nagpur Metro stands as a testament to India’s growing commitment to sustainable urban mobility solutions. By offering a rapid, reliable, and eco-friendly alternative to private vehicles, the metro is not only transforming the city’s transportation landscape but also paving the way for a cleaner and healthier future. While challenges such as achieving financial sustainability and ensuring seamless last-mile connectivity remain, Nagpur Metro’s unwavering focus on innovation and passenger experience positions it for continued success. As ridership grows and the network expands, Nagpur Metro is poised to become the backbone of a vibrant, connected, and sustainable Nagpur.

Efficient Friction Management and fuel technologies in Railways

Introduction

The history of Indian Railways dates back to over 160 years ago when the first passenger train in India departed for Thane, about 34 kilometers from Bombay’s Bori Bunder station. 400 people traveled on 14 vehicles pulled by three steam engines Sahib, Sindh, and Sultan, that pulled the 14-carriage train. The Great Indian Peninsula Railway was entrusted with the responsibility of running the passenger route. A 1,676 mm (5 ft 6 in) wide gauge track was used to build this train.

In India, there are several types of railway track systems used for passenger and goods transportation. The main types of railway track systems in India are Broad gauge (BG), Meter gauge (MG), Narrow gauge (NG), and Dual Gauge (DG). The major distinctions between these track systems are first, the distance between the tracks, and second the Speed, capacity, and Cost.

The distance between the tracks varies as:

Broad Gauge > Meter Gauge > Narrow Gauge

Broad gauge tracks can accommodate higher speeds compared to meter gauge and Narrow Gauge tracks. This means that trains on broad gauge tracks can travel faster and cover longer distances in a shorter time as compared to the other track types.

Broad gauge tracks have a higher capacity than meter gauge and Narrow Gauge tracks. This means that these can accommodate more passengers and freight, making them more efficient for transporting large volumes of goods and people. The cost of constructing and maintaining different types of railway track systems varies. Broad gauge tracks are generally more expensive to construct and maintain compared to meter gauge and Narrow Gauge tracks.

Overall, the choice of railway track system depends on factors such as the terrain, passenger, and freight traffic, and cost-effectiveness. In India, Broad Gauge tracks are the most commonly used due to their high capacity and ability to accommodate faster speed. The implementation of high-speed railways in India is in its early phases and vast studies are being conducted for the effective implementation of the system based on the specifics of our nation. Maintaining the traction required for efficient operation of trains at high speeds requires the net minimum frictional coefficient to be maintained at the wheel-rail interface across the desired range of axle loads and target speeds of train operation. With the increase in speed, wheels of the train tend to lift-off, effectively reducing the interface friction at the wheel-rail contact.

Railways’ huge efficiency advantage comes primarily from the technology of steel wheels rolling on steel rails. As steel is very hard, the shape of a train’s wheel does not change under load, and the rail-wheel contact area always remains minimal and very small, resulting in very low friction force to come into play. Further, since trains can be very long, typically 250-300 meters to a few kilometers (in case of freight) and can carry hundreds/thousands of passengers and several thousand tons of freight, the air drag force per unit of freight/passenger reduces drastically. All these factors result in huge efficiency gains in favor of Railways.

Railway is considered to efficient mode of transportation in India and elsewhere. As per the National Transport Development Policy Committee (NTDPC) Report of 2010, Railway consumes 75 to 90% less energy for freight and 5 to 21 % less energy for passenger traffic compared to road-based transport. Rail is over 8 to 10 times more efficient than road for passenger and freight transport depending on loads, operating conditions and technologies deployed. In simpler words, a liter of fuel can move 4 -10 units of passenger/freight by train compared to 1 unit by road vehicle.

Fuel efficiency leads to environmental benefits. Efficiency simply defined is “output per unit of input” Output of any railway system. It is commonly measured in terms of Gross Ton Km (GTKM) or Net Ton Km (NTKM) or Passenger Km (PKM) moved over the railway system in a given time frame. Key inputs to a railway system are in the form of fixed infrastructure like track, bridges, signals, traction power supply and distribution network, stations, rolling stock like locomotives, coaches and wagons, manpower like station staff, crew, infrastructure and rolling stock maintainers etc, fuel and materials.

Railway systems are characterized by high fixed costs (track, bridges,etc) and low variable costs (fuel, consumables etc) and so typically for increasing efficiency the fundamental need is to increase throughout in the railway system.In this subsequent content, we will discuss the knitty-gritties of efficient friction management and fuel technologies in Railways. Also, the different ways of improving fuel economy, EV ecosystem and the role of railways into all this.

Efficient Friction Management

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Efficient friction management aims to increase traction or grip and modify lubrication to consequently affect the behavior of passing wheels. These include reduced noise, improved fuel efficiency, protection of rail assets, or extended asset life.

Challenge

The continuous contact between the wheel and the rail surface is less than one square centimeter. Failing to manage the friction between the wheel and the rail reduces the life of wheel and rail that consequently increases the risk of derailment due to flange climb.

Friction at the wheel-rail interfaces in railway operations plays a significant role in maintaining sufficient traction, for running trains with safety and to have the ability to accelerate, decelerate or brake the train at specified locations on the railway track.

Maintaining the traction required for efficient operation of trains at high speeds requires a net minimum frictional coefficient to be maintained at the wheel-rail interface, across the desired range of axle loads and target speeds of train operation. With the increase in speed, wheels of the train tend to lift-off, effectively reducing the interface friction at the wheel-rail contact.

Rail Lubrication Scenario in India & Worldwide

In India, Rail & Flange (R&F) lubricators have been in use for long. These lubricators have a small tank of 1 to 2-liter capacity with a nozzle that oozes out grease as and when a wheel flange presses its actuator. These are not maintenance-free and have mostly gone out of use. The most commonly used method had been the manual application of graphite grease at a weekly or any other predetermined frequency on the gauge face of the outer rail in curves.

Inspired by the benefits reported by world railway systems, IR decided to give a trial to gauge face lubrication by installing Wayside lubricators from tried and tested brands. RDSO took the responsibility of zeroing upon the manufacturer based on Techno economic bids.

Canadian Pacific Railway (CPR) has spent the past 5 years implementing an optimized “100% effective gauge face lubrication” strategy on 3250 km of their 24,000 km network to control friction at the interface between the wheel flange / rail gauge face.

In Britain, lubrication has traditionally been provided as part of the infrastructure. Mechanical and hydraulic lubricators were placed in curves at the point where wheels commenced flanging contact.

Benefits

With an Efficient Friction Management mechanism in place, IR can achieve some of the below mentioned benefits.

Reduced asset whole life cost
Reduced track worker risk profile
Reduced track asset risk profile
Ensured Higher Safety and Smooth Ride
Lesser Noise
Reduced maintenance cost and high efficiency
Reduced centrifugal forces at radius curves
Lesser Derailment Risk at tight curves
Reduced Lateral Stress at flange contact
Reduced carbon footprint

Use of Friction Modifiers and Lubricant solutions

Friction modification is done through the use of lubrication solutions. It reduces the Rail / Wheel Wear (Gauge Face, Flange), rolling contact fatigue (RCF) development, Flange Noise, Derailment Potential (Wheel Climb), Lateral Forces (indirect), corrugations, vehicle hunting. At the same time it improves fuel efficiency and ride quality.

Wheel-Rail Interface Lubrication: Innovative lubrication systems are deployed to reduce friction at the wheel-rail interface. This not only extends the lifespan of these components but also reduces the energy required to overcome rolling resistance.
Condition-Based Maintenance: Using sensors and IoT (Internet of Things) technologies, railways can now monitor the condition of tracks and rolling stock in real-time, optimizing maintenance schedules to ensure minimal friction and wear.
Aerodynamic Design: Reducing air resistance through better design of train bodies also contributes to friction management, albeit indirectly, by improving overall energy efficiency.

Fuel Technology in Railways

Under the flagship programs of the Government, “Advanced Chemistry Cell (ACC) Batteries” and “National Hydrogen Mission”, to cut down on the Green House Gases (GHGs) emission under Paris Climate Agreement 2015 and “Mission Net Zero Carbon Emission Railway” by 2030, Indian Railways is set to run trains on hydrogen fuel-based technology.

Going Electric

Today, 94% of the Indian rail network stands electrified. Indian Railways has become the country’s largest consumer of electricity, and the impact of this shift towards electrification on the country’s energy independence is significant. By 2030, the total energy requirement of the Railways is expected to increase to 8,200 MW, or 8. 2 GW. Out of this, 700 MW or 8.5% will be sourced from Coal Plants due to existing agreements. Remaining 91.5% is planned to be sourced from renewable energy sources like Hydro Power Plant, Solar Energy.

Focus on Non Renewable Source of Energy

We need to focus more on distinct renewable energy sources like Hydro Power Plant, Solar Energy to be converted into mechanical energy through solar plants along with wind Energy, which is also a major source of renewable energy. These will contribute to the Net Zero Carbon Emission goal of Indian Railway as well and making the world a better place eventually.

Indian Railways, in its ambitious move towards sustainability, has significantly ramped up its renewable energy capacity, commissioning about 211 MW of solar plants and around 103 MW of wind power plants as of October 2023. With the expansion of routes and trains every year, the power demand for metro corporations is also increasing at massive speed, which is expected to put tremendous pressure on the country’s urban power supply.

With an aim to increase the renewable energy resources’ contribution in Indian Railways and urban metro system various initiatives have been taken by theIndian Railways. For Indian Railways, which has set the target of the 500MW energy from the solar rooftop, 96.84 MW of solar plants have been installed, and 16 stations have been declared as green railway stations across zones.

We have upgraded our fuel technologies into the 3rd generation namely from Steam Engines to Diesel Engines,Diesel to finally Electricengines. Now the world is moving towards the cleanest type of fuels like Hydrogen, etc. It is already in the testing phase and very soon we will witness a prototype deployed by the Indian Railways for the same.

Hydrogen Fuel-Based Technology

Hydrogen trains use hydrogen fuel cells instead of diesel engines. These cells produce electricity by combining hydrogen and oxygen, which generates electricity which is further used to power the train’s motors.

As per PIB press release dated 3^rd Feb 2023, Minister of Railways, Communications and Electronic & Information Technology, Shri Ashwini Vaishnaw informed Rajya Sabha that Indian Railways (IR) has envisaged running 35 Hydrogen trains under the “Hydrogen for Heritage” initiative.

IR has also awarded a pilot project for retro fitment of Hydrogen Fuel cell on existing Diesel Electric Multiple Unit (DEMU) rake along with ground infrastructure at the cost of ₹ 111.83 crores which is planned to hit the tracks on Jind –Sonipat section of the Northern Railway.

The use of Hydrogen as fuel provides larger benefits in the direction of green transportation technology to support zero carbon emission goals as a clean energy source. It has no adverse environmental impact during operations as the byproducts are simply heat and water. Unlike bio-fuel or hydropower, hydrogen doesn’t require large areas of land to be produced.

Commercial operations of hydrogen-powered trains would take India into an exclusive club of railway systems operating emission-free locomotives. Currently, only Germany operates commercial hydrogen-powered trains, while the same technology remains in the testing phase in the US, the UK, France, and Japan.

Advancements in Fuel Technologies:

Hybrid and Fully Electric Trains: The shift towards hybrid and fully electric trains represents a significant leap in reducing the reliance on fossil fuels. Electric trains offer vastly improved efficiency and lower emissions as compared to their diesel counterparts.
Alternative Fuels: Research into alternative fuels, such as bio-fuels and hydrogen fuel cells, provides promising avenues for reducing the carbon footprint of non-electrified sections of the railway network.
Regenerative Braking Systems: These systems capture energy typically lost during braking and convert it into electrical energy, which can be either used to power the train or fed back into the grid, further improving the overall fuel economy.

Consumption of Fuel/Energy

In Railways, mileage is not measured in kmpl but liters per 1000 GTKM (gross tonnage hauled per km) or specific fuel consumption. Average figure ranges from 4 – 4.5 liters per 1000 GTKM for a passenger train and for goods train it is 2.25 to 2.75 liters per 1000 GTKM.

A tarin consumes roughly 15 units per Gross tonne km (GTKM) for passenger trains like Rajdhani etc and 10 units per gtkm for goods trains.

A WAP-4 locomotive has 6 DC traction motors and 3 auxiliary motors and it consumes around 840–1080 KW in an hour Or 6500 KW-8500 KW in 8 hours. Whereas a 3 Phase locomotives like WAG-9, WAG-9H, WAP-7 have regenerative braking system that saves the consumption of electricity up to 20% . These locomotives consume electricity around 720 KW -840 KW per hour 5760 KW -6720 KW in 8 hours.

The cost of running a diesel locomotive for 1 kilometer in Indian Railways varies depending on a number of factors, including the type of locomotive, the weight of the train, and the distance traveled. However, the average cost is around ₹280 per kilometer.

Improving Fuel Economy

Fuel Economy is measured in terms of SFC (specific fuel consumption). It is the amount of fuel consumed per unit of work done. In Indian Railways SFC is measured both for the engine and the train to assess the performance of the engine as well as the total formation of the train. It is obvious that a lower SFC is the indication of a better Fuel Economy.

CRIS has already developed a fuel management system for Indian Railways. However there is a huge scope for improvement in the fuel economy.

Aerodynamic Enhancements and Lightweight Materials: By investing in research to make trains more aerodynamic and using lightweight materials for construction, railways can significantly reduce energy consumption.
Smart Routing and Scheduling: Advanced algorithms and AI can optimize routes and schedules, reducing idle times and ensuring trains run at speeds that maximize fuel efficiency.

Role of Railways in the EV Ecosystem

In recent years, the development of electric vehicle (EV) infrastructure and efforts to achieve more sustainable transportation systems have increased. The enhanced utilization of EVs will require fast charging systems, which will overload utility power grids and require high-cost additional installations and equipments.

There are 123 redeveloped railway stations in India where NITI Aayog has recommended the installation of EV charging facilities immediately, rather than waiting until 2030. Because of their unique role in the transportation industry, railway stations make an ideal location for installing public charging stations for electric vehicles.

Railway stations can provide a secure and accessible charging infrastructure for city residents, in addition to existing government initiatives. Many Indian Institutes of Technology (IITs) researchers have developed new charging technology for electric vehicles, which is half the price of the current onboard charger technology. Two and four-wheeled electric vehicles can benefit greatly from these.

However, a significant amount of regenerative braking energy (RBE) is available in electric railway systems (ERSs), which needs to be properly stored and accommodated. The integration of ERSs and EV charging stations (EVCS) at strategic points, such as parking areas close to ERS stations or rail freight intermodal terminals where EVs are parked most hours of the day, can be a promising solution to save RBE in the dedicated internal EV batteries.

Budget 2024-25 announcement

Union finance minister Nirmala Sitharaman while presenting the Interim Budget for 2024-25 announced to set up three major railway corridor programmes for energy. The interim budget allocation has bettered that record and assigned Rs 2. 55 trillion to the Indian Railways. It is aimed at addressing congestion and reducing cost of logistics. It is obviously going to to boost economic growth. The announcement is the government’s forward looking financial roadmap focusing on green energy.

The three corridors are poised to significantly boost economic growth and streamline logistics for industries, thereby enhancing overall efficiency. A slew of proposals announced in the budget for startups and electric vehicle ecosystem would also accelerate the sector and encourage entrepreneurship.

Dedicated freight corridors (DFC), with appropriate technology, enables the Indian Railways to regain its market share of freight transport. It also creates additional capacity and assures efficient, reliable, safe, and cheaper options for mobility to customers.

There are many ongoing projects to charge EVs by transferring RBE from ERSs to EVCSs, taking advantage of a combined power management scheme based on stationary hybrid energy storage systems (HESSs) integrated with railway power flow controllers (RPFCs).

EV Charging Stations

Government of India (Gol) has identified promotion of Electric Vehicles (EVs) as a major step towards decarbonization of the transportation sector and reduceing demand for petroleum products, and has taken a slew of initiatives to encourage large scale EV adoption.

Further to promote an accessible and robust network of EV charging infrastructure, the Ministry of Power (MoP)- Gol had issued guidelines on charging infrastructure. The guidelines issued by the MoP has recommended setting up of at least one public EV charging station in a 3X3 km grid in a city and one charging station at every 25 km on both sides of highways or roads.

IR intends to replace its existing fleet of (owned / hired / leased) Internal Combustion Engine (ICE) cars used by IR employees with EVs across the country. Battery Swapping facility is also going to enhance user friendly activities at EV charging stations.

Affordable and accessible charging infrastructure is a prime concern today. IR has started to identify and allocate parking spaces in its office complexes and stations to be used for EV charging facilities. Zonal Railways has also explored the possibility of setting up Battery Swapping Stations (BSS) for E-Vehicles.

Integration of Infra & Services

Charging Infrastructure: Railways can play a pivotal role in developing the EV charging infrastructure. Integration of charging stations at or near railway stations can facilitate the accessibility of the charging points making easy charging for electric vehicles available to all, thus encouraging its use.

Last-Mile Connectivity: Electric trains coupled with EVs for last-mile connectivity can create a seamless &eco-friendly transportation network. This synergy can significantly reduce urban congestion and pollution levels.
Energy Management: Railways can leverage their large, often continuous, demand for electricity to foster renewable energy investments, such as solar or wind power installations along tracks or on unused land. This green energy can power electric trains and EV charging stations, closing the loop on sustainability.

Conclusion

Since 1850s when the first train ran in India and royal families sponsored its expansion to the present-day envious network and 13523 trains running daily, railways has connected India like nothing else. In order to achieve net zero emission and zero carbon footprint, IR has to make continuous sustainable improvements. Technical advancement is the key contributor. Research and Developments need to take place more frequently. Efficient friction management is prime concern for high speed trains and need to be properly addressed. Improvement in fuel economy, fuel technology is urgent requirement. Growing EV Ecosystem demands robust software system and world class infrastructure. All stakeholders including department respective officials, government, policymakers need to gear up for the upcoming challenges.
