3 February 1925 was the day when Indian Railways began its journey of electrification. After 100 years, today this journey is nearing completion. Railway electrification now stands as a major component in Indian Railways’ strategy to lower its carbon footprint. As of August 2025, approximately 99.1% of the broad-gauge network has been electrified, which covers 69,154 route kilometres out of a total of 69,800. This rapid progress reflects an accelerated pace of electrification, which has increased from 1.42 kilometres per day during 2004–2014 to 19.7 kilometres per day in 2023–2024.
The transition from diesel to electric traction offers multiple advantages. It reduces greenhouse gas emissions, increases energy efficiency, and decreases operational costs in the long run. Moreover, electrified railways facilitate the integration of renewable energy sources, which aligns with India’s broader goal to achieve sustainable development. Indian Railways plans to meet its projected traction power requirement of 10,000 MW by 2030 through a diversified energy mix, including solar, wind, and nuclear power. This comprehensive approach outlines the critical role of electrification in India’s journey toward a low-carbon future.
In this article, we will delve into the technical aspects of railway electrification, examine its environmental and economic benefits, and assess its impact on the decarbonisation of railways.
Key Factors of Railway Electrification and the Transition from Diesel Locomotives
Railway electrification in India commenced in 1925 with the commissioning of a 16 km section in Mumbai. This was the first operational use of electric traction in the country, which laid the foundation for energy-efficient and higher-capacity rail transport.
Between 1947 and the early 21st century, electrification progressed in a phased and strategic manner, and focused on high-density commuter corridors, key intercity routes, and freight-heavy sections. These initiatives were integrated into Indian Railways’ five-year planning cycles, which necessitated systematic expansion, operational efficiency, and the adoption of technological standards for electric traction.
Many financial, technical, operational, and environmental factors have driven the transition from diesel locomotives to electric traction. These factors include:
Dependence on Oil Imports
The first diesel locomotive was introduced in India in 1954. Despite this, steam locomotives, powered by domestic coal reserves, continued to dominate operations until the 1980s. The large-scale adoption of diesel traction modernised the railway network but also increased dependence on imported crude oil. India sources nearly 80% of its petroleum requirements from abroad. This dependence exposed railway operations to fluctuations in international oil prices, creating pressure to manage operational costs while keeping fares and freight charges affordable. In response to the oil crisis, Indian Railways began to accelerate its electrification programs from the 1980s onward.
Note: Indian Railways reduced traction fuel consumption by 136 crore litresbetween the 2018–19 and 2023–24 fiscal years. This reduction is largely due to the ongoing “Mission 100% Electrification” initiative, which has accelerated the transition from diesel to electric traction across the network.
Higher Energy Efficiency
Electric locomotives use energy more efficiently than diesel engines. About 95% of the electricity generated is converted into motion at the wheels, while diesel engines only use around 30% of the fuel energy. This means electric trains consume less energy and cost less to run, which makes them more economical and effective for the railway system. Modern electric locomotives can also use regenerative braking, saving an additional 15–20% of energy.
Greenhouse Gas Emissions
Diesel locomotives produced high levels of greenhouse gas emissions. In 2017–18, diesel combustion alone contributed over 7.5 million tons of carbon dioxide equivalent, accounting for more than 90% of the railway network’s total emissions. Studies by the IEA and UIC in 2015 reported that Indian Railways emitted approximately 11.5 grams of CO₂ per passenger-kilometre and 9.5 grams of CO₂ per ton-kilometre of freight. The high level of emissions has been one of the critical factors that has accelerated the pace of electrification.
The Pace of Railway Electrification in India Over a Century
India electrified 45% of its railway network in just five years. Between 2014 and 2019, Indian Railways electrified approximately 30,000 route kilometres.
In January 2015, a major shift occurred when the National Railway Board established an Environment Directorate to coordinate environmental and sustainability initiatives across the Indian Railways network. At that time, the railway network operated a mix of diesel and electric locomotives, with approximately 45% of routes electrified.
The centralised investment and planning through the Environment Directorate accelerated electrification. Between 2019 and 2023, the network was electrified at a rate of 16 route kilometres per day, nearly double the rate of the previous five-year period and nine times faster than earlier efforts.
Electrification Rate of Indian Railways (Average Route Kilometres per Day, RKM/Day)
Since 2014, about 40,000 km of railway lines have been electrified in India, compared to 21,801 km electrified in all the years before 2014. This shows that the pace of railway electrification has been the fastest in the last 15 years. Between 2011 and 2020, around 20,000 route kilometres (rkm) were electrified. This progress has continued steadily, with another 20,000 rkm electrified between 2020 and November 2023.
Current Status of Railway Electrification
As of August 2025, Indian Railways has electrified 69,154 route kilometres out of a total of 69,800 km, achieving a 99.01% electrification of its broad gauge network. A total of 646 Route Kilometres (RKM) remains unelectrified, which lies in five states: Assam, Rajasthan, Karnataka, Tamil Nadu, and Goa. Assam has the highest proportion of unelectrified tracks, with 269 RKM, which constitutes nearly 10% of its total railway network. Rajasthan follows with 93 RKM, which is less than 1% of its overall network pending electrification.
The Impact of Railway Electrification
Decarbonisation of Railways
Electrification of railway lines is a central component of the Indian Railways’ long-term strategy to modernise its infrastructure and reduce environmental externalities associated with diesel traction. The Indian Railways operates one of the largest transport networks in the world. A portion of this operation is still dependent on diesel locomotives, which generate considerable quantities of carbon dioxide (CO₂), nitrogen oxides (NOₓ), particulate matter (PM), and other pollutants. The transition to electrification directly addresses these issues by shifting to electric traction, which not only lowers greenhouse gas emissions but also improves efficiency of operations, given that electric locomotives provide higher power-to-weight ratios and faster acceleration.
A main driver for railway electrification is India’s stated objective of achieving net-zero carbon emissions from the railway sector by 2030. This target requires a comprehensive approach, where complete electrification is a prerequisite. When Electric locomotives are powered by grid electricity, which is sourced from renewable energy, they have negligible direct emissions. Electric traction systems achieve efficiency levels above 90%, which directly reduces energy demand per unit of transport service delivered. This efficiency results in less primary energy consumption, lower operational costs, and a substantial decline in the overall carbon footprint of railway operations.
Integration of Renewable Energy
Another critical dimension of electrification’s role in decarbonisation is its integration with India’s renewable energy sector, particularly solar power. The Government of India is scaling up renewable capacity nationwide, and Indian Railways has aligned its energy strategy to directly source clean electricity for traction and non-traction purposes. Installed solar capacity across the railway network has already crossed 4,500 MW, combining both rooftop and land-based installations. IR has commissioned rooftop solar panels at 2,427 stations, 1,295 service buildings, and 673 residential quarters, which contribute to a cumulative 236 MW of generation capacity.
An additional 224 MW of rooftop capacity is under implementation. To ensure a reliable supply of renewable power for its high-demand operations, Indian Railways is also deploying 2,301 MW of round-the-clock renewable energy (RE-RTC) capacity in Rajasthan and Maharashtra. These measures enable the electrified railway network to progressively decouple from coal-based power generation and transition to a cleaner, more stable energy mix. The integration of solar energy with electrification not only reduces the system’s dependence on fossil fuels but also enhances long-term energy security by lowering exposure to fluctuations in global fuel markets while simultaneously reducing the carbon footprint of railway operations.
Limitations of Electrification: The Gaps in Net-Zero Carbon Emission Pathway
Electrification Alone Does Not Equal Decarbonisation
Even if Indian Railways achieves 100% electrification in the coming months, this milestone will not in itself result in full decarbonisation of operations. Electrification primarily eliminates the direct use of diesel traction but does not automatically address the carbon intensity of the electricity that powers the railway network. At present, a proportion of India’s grid electricity is still generated from coal-based thermal plants, which remain the dominant source in the national energy mix. As a result, while the shift from diesel to electric traction reduces local air pollution and improves energy efficiency, the overall carbon footprint of the railway system continues to be linked to fossil-fuel-based electricity generation.
This creates a gap between electrification and decarbonisation. Electrification represents the transition of traction power supply from internal combustion to electric systems, but true decarbonisation requires that the electricity used be sourced from non-fossil-fuel-based renewable energy such as solar and wind. Without this transition, the indirect emissions associated with coal-based power generation persist, thereby limiting the environmental gains of electrification.
Increase in Balancing Costs The Climate Policy Initiative’s study (2017) on the decarbonisation of Indian Railways highlights this gap clearly. The study found that full decarbonisation of traction power by sourcing electricity from renewable energy could be 26–28% cheaper than the business-as-usual pathway by 2030. However, this transition requires more than just connecting to the grid; it demands a deliberate shift in sourcing electricity from coal-based supply to a diversified renewable mix. The report highlights that relying solely on solar power would make the system heavily dependent on balancing mechanisms, which will increase the balancing costs to as much as 63–78% of the total cost. An optimal mix of wind and solar, where wind capacity is nearly 8 times greater than solar, can limit balancing costs to just 5–8% by 2030 and ensure a better match between supply and demand.
Renewable Integration and Balancing Challenges
Source: CPI Study
This brings out a second gap. Decarbonisation is not simply about installing solar panels or building wind farms, but about ensuring uninterrupted supply reliability. Wind and solar power are variable, with generation depending on time of day and seasonal patterns. The CPI study mentions that Indian Railways would require renewable capacity about 6 times its electricity demand, as well as power banking or energy storage mechanisms, to manage variability. Without these systems, the Railways would remain dependent on coal-heavy grid supply to cover shortfalls, which would undermine its decarbonisation goal.
Policy and Regulatory Barriers
Another gap is in policy and rules. The CPI study pointed out that current laws and regulations make it harder for Indian Railways to use renewable energy. Some states do not recognise the Railways’ rights to transmit and distribute electricity, which slows down the creation of a national system to balance electricity supply. It is also difficult for the Railways to set up affordable storage or power banking to manage changes in renewable energy supply. These problems make it harder for Railways to buy renewable electricity and keep a steady power supply.
Conclusion
The electrification of the railway network is not an isolated infrastructure upgrade but a systemic intervention that closely aligns with the broader climate and sustainability objectives of Indian Railways and the nation. Currently, 69,154 route kilometres out of a total of 69,800 km of the broad gauge rail network have been electrified, which accounts for 99.1% of the network. The strategy to electrify the railway network forms the backbone for decarbonisation, as it provides multifaceted benefits such as a reduction in carbon emissions and lower operational and maintenance costs. In addition, the transition to electric traction from diesel will ease the burden of crude oil imports and make the Railways economically sustainable.
Although electrification is important, it is not enough. To really reduce carbon emissions, Indian Railways needs to source large amounts of renewable energy, use an optimal mix of wind and solar power, invest in storage and backup systems, and address policy and regulatory barriers. Only when these gaps are filled can electrification lead to real decarbonisation and help Railways reach net-zero carbon emissions by 2030.

Braking systems form one of the most critical subsystems in railway engineering. They directly influence the safety, reliability, and operational efficiency of train operations. The ability to control train speed and ensure a predictable stop within a defined braking distance is fundamental for both passenger and freight operations. As the demand grows for high-speed train operations, traditional braking methods such as vacuum and conventional pneumatic brakes have proven inadequate in meeting modern performance and safety requirements.
Modern rail vehicles now rely on advanced braking technologies that combine mechanical, pneumatic, and electrical principles to deliver better responsiveness, energy efficiency, and fail-safe operations. These systems not only reduce stopping distances but also integrate with train control and protection mechanisms, such as Automatic Train Protection (ATP) and India’s indigenous Kavach system, to prevent accidents arising from human error or equipment failure.
Additionally, energy recovery through regenerative braking, widespread adoption of disc-based systems, and the use of contactless braking solutions such as eddy current and magnetic track brakes have converted braking into a multi-functional system that ensure safety while contributing to sustainability.
This paper explores the critical role of modern braking systems in enhancing the safety, efficiency, and reliability of rail transit operations. As metro rail, high-speed rail, and suburban transit systems expand globally, the demand for advanced braking technologies is increasing proportionally. Modern brakes are no longer limited to mechanical stopping functions, as they now incorporate regenerative energy recovery and electronic control. They are aligning with the industry’s push for efficiency and sustainability.
Along with technical improvements, the development of modern braking systems is also creating business opportunities for manufacturers. Investments in new metro and high-speed rail projects, the replacement of older rolling stock, and the enforcement of stricter safety standards are increasing the demand for reliable and efficient braking solutions. This paper looks at both the technical side of braking systems and the market potential.
Evolution of Railway Braking Systems
The development of railway braking technology has been closely linked to the increase in train speeds, axle loads, and passenger safety requirements over the last century. Early railways primarily relied on hand-operated mechanical brakes, which were applied by guards or brakemen stationed in individual wagons. This system was highly inefficient, inconsistent, and unsafe, particularly for long freight trains.
To overcome the limitations of mechanical brakes, vacuum brakes were introduced in the mid-1860s. Vacuum brakes, while simpler in construction, suffered from limited braking force and slower response times, especially on long rakes. Their performance under adverse weather conditions and at higher speeds also created challenges.
The invention of the compressed air brake by George Westinghouse between 1869 and 1872, turned out to be a major technological leap. Pneumatic air brakes allowed for simultaneous braking across the entire train. This reduced stopping distances and improved safety. Over time, this system evolved into electro-pneumatic (E-P) brakes, which use electrical signals for faster actuation and more uniform brake application.
As the modern rolling stock entered operations, further innovations were introduced. Disc brakes provided superior performance compared to tread brakes, especially at higher speeds, while regenerative and rheostatic braking systems enabled energy recovery and reduced wear on mechanical components. In parallel, contactless technologies such as eddy current and magnetic track brakes were developed to provide additional emergency braking capacity, particularly for high-speed rail applications.
This gradual progression from manual to highly automated, multi-modal braking systems reflects the increasing emphasis on reliability, safety, and efficiency in modern railway operations.
Types of Modern Brake Systems
Modern rail vehicles employ a combination of mechanical, pneumatic, and electrical braking technologies to meet the demands of higher speeds, improved safety, and operational efficiency. The main systems in use today include:
Electro-Pneumatic Brakes
Electro-pneumatic (E-P) brakes are an improved form of the conventional air brake. They were first used in the United States on the New York Subway in 1909 and later on the London Underground in 1916.
In this system, the main braking power still comes from compressed air acting on the brake cylinders, but the control of the brakes is done electrically. Instead of relying on air pressure changes to travel through the brake pipe, electrical signals are sent along the train. These signals reach electro-pneumatic valves on each vehicle, which then allow compressed air from the reservoirs to enter the brake cylinders. This makes the brakes apply and release almost instantly and at the same time across the whole train.
E-P brakes are mainly used in multiple-unit passenger trains and metro systems, where quick and reliable braking is required. Their main benefit is faster response compared to conventional air brakes, which improves train handling, reduces stopping distance, and allows closer train spacing. The system is also suitable for use with automatic train operation (ATO) and train protection systems.
For safety, the conventional pneumatic brake system is usually kept as a backup. If the electrical control fails, the air brake still works to bring the train to a stop in an emergency situation.
Regenerative and Rheostatic Braking
Modern rail systems increasingly rely on energy-efficient braking technologies that not only slow the train but also recover or dissipate energy. Regenerative braking captures the kinetic energy of a moving train and converts it into electrical energy, which can be fed back into the power supply system or reused.
Working Principle: During braking, the train’s traction motors operate as generators. The kinetic energy of the train is converted into electrical energy, which flows back into the traction power network if the infrastructure allows. If the network cannot absorb all the generated energy, it is dissipated as heat through rheostatic braking, where resistors onboard the train convert the energy into thermal energy. Rheostatic braking ensures that braking remains effective even when regeneration is not possible, such as during low power demand or network faults.
Many metro systems, including the Delhi Metro, Kolkata Metro, Pune Metro (Metro Line 3), and Indore Metro, utilise regenerative braking technology to convert the train’s kinetic energy into electricity.
Disc Brakes
As the speed of rail transportation increased with technological progress, the demands on braking systems also grew. Higher speeds mean greater kinetic energy, which must be converted into heat during braking. Traditional block (or tread) brakes, which press brake blocks directly against the wheel tread, were adequate for lower speeds but became less effective as trains got faster and heavier.
Disc brakes emerged as a response to these challenges. In a disc brake system, friction pads press against a disc mounted on the wheel or axle, rather than directly on the wheel tread. This design allows better heat dissipation, consistent braking performance, and reduced wear on wheels.
The practical applications appeared in the 1930s. In the United States, the Budd Company introduced disc brakes on the General Pershing Zephyr, which was a passenger train built in 1938 and placed into service in 1939. By the 1950s, disc brakes had become standard on new-generation passenger coaches and were later essential for high-speed trains such as the Shinkansen and TGV.
Modern Applications of Disc Brakes
Metro and EMU Systems
Disc brakes are widely used in modern metro trains and electric multiple units (EMUs), where frequent stops and starts demand reliable and consistent braking. In these systems, disc brakes are often combined with regenerative braking to recover energy and reduce wear on mechanical components.
LHB Coaches in India
In India, LHB (Linke-Hofmann-Busch) coaches have replaced older ICF coaches, which used traditional tread brakes. LHB coaches employ disc brakes to handle higher speeds
Eddy Current Brakes
Eddy current brakes are a type of non-contact braking system that uses electromagnetic induction to slow down a train without physical friction. They are commonly used in high-speed trains, magnetic levitation (maglev) systems, and as supplementary braking systems where conventional mechanical brakes are less effective.
Working Principle of Eddy Current Brakes
Eddy current brakes operate on the principle of electromagnetism and provide contactless braking. A conductive disc is mounted on the axle, with electromagnets positioned near it. When the driver applies the brakes, the electromagnets are energised, creating a magnetic field. As the disc rotates through this field, eddy currents are induced in the disc. These currents generate an opposing magnetic field according to Lenz’s Law and produce a resistive force that slows the train without any physical contact.
Because braking is achieved through electromagnetic forces rather than friction, there is no wear on the wheels or brake pads. This makes the system especially suitable for high-speed trains and maglev vehicles. Eddy current brakes are generally used as supplementary brakes alongside mechanical brakes, particularly at high speeds where conventional brakes may overheat or become less effective.
Eddy current brakes offer several advantages, especially for high-speed rail applications. Since they operate without physical contact, there is no wear on wheels, brake pads, or discs, which reduces maintenance requirements. They perform efficiently at high speeds and provide smooth and consistent braking even when mechanical brakes might overheat. Additionally, because no friction is involved, the system operates quietly and vibration-free.
However, the Eddie Currentbrake system has some limitations. Eddy current braking force decreases at low speeds, so mechanical brakes are still needed for final stopping. Unlike regenerative braking, the energy is dissipated as heat and not reused in this system.
Magnetic Track Brake
Magnetic track brakes are a type of electromagnetic braking system commonly used in metros, light rail, and trams to provide rapid and reliable stopping, particularly in emergency situations. Unlike conventional brakes that act on wheels, magnetic track brakes act directly on the rail itself. MTBs are not the primary braking system but serve as a powerful, supplementary brake during emergencies or when adhesion between the wheel and rail is low.
Magnetic Track Brakes (MTBs) can deliver adhesion forces of up to 100 kN, which makes them effective even under challenging conditions. Modern MTBs are designed with a low profile, as small as 130 mm in height, to minimise space requirements and integrate easily into vehicle bogies. They are used as supplementary braking systems in high-speed trains, such as Germany’s ICE, where they operate alongside disc and regenerative brakes to ensure safe and reliable deceleration. MTBs are also extensively employed in metro and tram systems for emergency stops or rapid deceleration. Primary examples include the Delhi Metro, London Docklands Light Railway (DLR), and Munich U-Bahn, where they provide consistent braking performance even on wet or slippery tracks.
Integration with Safety and Train Control Systems
Modern braking systems do not operate in isolation. They are closely integrated with train safety and control mechanisms to ensure predictable and fail-safe operations. This integration allows braking systems to respond automatically to potential hazards to avoid any human error.
Automatic Train Protection (ATP) and Automatic Train Operation (ATO):
ATP systems continuously monitor train speed, track conditions, and signal aspects. If a train exceeds the permitted speed or approaches a danger point, the ATP system automatically triggers braking to prevent collisions.
ATO systems, used in metros and high-speed rail, control train acceleration and deceleration, including braking, to optimise schedules and maintain safe headways. Electro-pneumatic brakes and regenerative systems are particularly suited for ATO due to their fast response and precise control.
Indigenous Safety System in India:
India’s Kavach system integrates with braking mechanisms to enhance train safety. If the driver fails to respond to a signal or an obstacle is detected on the track, Kavach can automatically activate the brakes, including E-P and disc brakes, to ensure that the train stops within a safe distance.
Limitations of Modern Braking Systems
Electro-Pneumatic (E-P) Brakes E-P brakes rely on electrical signals to achieve fast and uniform braking across the train. This dependence on electricity makes them vulnerable to power failures or faults in the control wiring. While conventional pneumatic brakes serve as a backup, any malfunction in the electrical system can affect responsiveness, leading to a threat to safety.
Disc Brakes Disc brakes perform well at higher speeds and provide consistent braking, but prolonged use generates heat that can lead to thermal stress and potential brake fade. In metro and suburban operations with frequent stops, friction pads experience accelerated wear, necessitating periodic replacement. Noise and vibration may also occur under certain conditions, although modern materials mitigate these issues to some extent.
Eddy Current Brakes
Eddy current brakes are highly effective at high speeds but lose efficiency at low speeds makes it necessary to rely on supplementary mechanical brakes for final stopping. The energy generated is dissipated as heat rather than recovered, which limits overall energy efficiency.
Magnetic Track Brakes (MTBs) MTBs are designed primarily for emergency or supplementary braking rather than continuous service braking. They require high electrical power to achieve strong magnetic adhesion and, if they are used frequently, they can cause localised wear or damage to the rail surface.
Regenerative and Rheostatic Brakes: Regenerative braking efficiency depends on the ability of the power network to absorb returned energy. When regeneration is not possible, rheostatic braking dissipates energy as heat, which creates thermal stress on resistors. Both systems require careful coordination with mechanical brakes to ensure safe stopping distances, particularly at low speeds or during emergency braking situations.

The main reasons for this increase are urbanisation, population growth, and government investment in railway infrastructure. Large projects such as high-speed rail, Dedicated Freight Corridors, and the rapid growth of metro networks in many cities are creating more demand for modern braking systems.
Older technologies, such as tread brakes on ICF coaches, are being replaced with disc brakes and electro-pneumatic brakes in LHB coaches and metro trains. At the same time, there is a move toward regenerative braking and integration with Automatic Train Operation (ATO) in new systems.
The focus on safety, efficiency, and reliability is influencing the market. India is gradually adopting braking systems that match international standards. This market trend creates opportunities for brake system manufacturers, suppliers, and rail operators to adopt and provide modern braking solutions across different regions.
Conclusion

Over time, brakes have moved from manual and vacuum systems to electro-pneumatic, disc, regenerative, eddy current, and magnetic track brakes. These changes have come with the need for higher train speeds, heavier loads, and stricter safety requirements. Modern systems also work with train protection and control systems, and in some cases, recover energy, which makes them more efficient than older brakes.
