CHENNAI (Metro Rail News): Chennai Metro Rail Limited (CMRL) recently awarded a contract to a contractor for the construction of an underground metro line to connect main city areas such as Marina Beach, Mylapore, Alwarpet, Nandanam, and T Nagar.

ITD Cementation India Limited has been awarded contracts to build twin tunnels and ten underground stations between Lighthouse at Marina Beach and the Kodambakkam overpass, according to officials. The 10-kilometre route will be part of the 26.1-kilometre corridor-4 bypass that runs from the Lighthouse to Poonamallee.

Contracts for the entire corridor-4, as well as the Poonamallee depot, have been granted as a result of this. While the new length has a four-year deadline, the 118.9-kilometre phase-2 is projected to be completed by 2026.

R Ramanathan, former CMRL director stated “Once a tender is awarded for an underground stretch, it usually takes an average six months for the construction to begin because the firm has to mobilise machinery and manpower. In case of underground lines, they have to import tunnel boring machines”.

The construction firm was awarded contracts for two underground stretches on corridor-4, from LightHouse to Bharathidasan Road station, spanning a 5.15-kilometer underground line with five stations, according to officials. Light House, Kutchery Road, Alwarpet, and Bharathidasan Road are among them. As part of corridor-3, an interchange station connecting corridors 3 and 4 will be built at Thirumayilai (Mylapore).

A 4.87-kilometer underground line from Boat Club to the Kodambakkam flyover is part of the other contract. Five stations will be located at Boat Club, Nandanam, Panagal Park, Kodambakkam, and the Kodambakkam flyover, as well as a crossover at Panagal Park enabling trains to change tracks.

According to Ramanathan, the diaphragm wall or outer walls of the stations are normally erected by cutting through the soil from the road’s surface before the tunnel construction begins. Then the soil within the four walls will be excavated before tunnel boring machines are assembled and deployed through a shaft cut through the soil. It’s possible that the construction of the walls will take a few more months.

DMRC and Reliance Infra’s DAMEPL summoned by SC to appear before the Delhi HC on January 31

DELHI (Metro Rail News): The Supreme Court on Monday ordered the Delhi Metro Rail Corporation (DMRC) and Delhi Airport Metro Express Pvt Ltd (DAMEPL), a Reliance Infrastructure’s subsidiary, to appear before the Delhi High Court on January 31 and requested that the dispute over the execution of an arbitral award worth over Rs 4,600 crore be heard as soon as possible.

According to a bench of Justices L Nageswara Rao and B R Gavai, the hearing on the execution application cannot be postponed any longer because it is injurious to both parties interests. On September 9, 2021, the Supreme Court upheld DAMEPL’s 2017 arbitration award of roughly Rs 4,600 crore, which was enforceable against the DMRC.

DAMEPL’s senior counsel, Mukul Rohatgi, argued that the corporation is facing a flurry of legal actions. “There is no defence after the apex court has upheld the order. Let them deposit the money. The court can give them a few months, but the execution cannot be stalled for no reason,” he stated.

Senior advocate Parag Tripathi, representing DMRC, stated that it was willing to assume DAMEPL’s liabilities up to the amount of the award money because it would be in a stronger position to bargain with the lender banks. He claimed that they had agreed to the proposal in their conversation.

On the other hand, Rohatgi stated, “I will deal with my creditors myself. Who is he to deal with my creditors?” DAMEPL wrote to DMRC on December 30, 2021, asking whether it was willing to take over its debt, which was to be paid by DAMEPL and Reliance Infrastructure to their lenders, according to Tripathi.

After that, the bench inquired, “What is this? There is an award in their favour, which this court confirms. Now you are saying we will negotiate with your bankers.” Tripathi argued that taking on a sudden obligation would jeopardise public interest, resulting in the closure of metro operations not only in this city but in five others as well.

Tripathi exclaimed, “I am not running away. I have deposited Rs 1,000 crore after the order. All I am saying is permit me to negotiate. We asked what the total dues were.” “Where is the question of negotiating when he says pay me my money,” the Supreme Court ruled. Tripathi said he had stated as much and cited letters to back up his claim.

Tripathi submitted, “I have money for Nagpur, Patna and cities. These are special grants from various authorities, including multilateral loan agencies. If these are attached, it will create a severe problem. I am not running away. I am not a fly by night operator.” “What issue do you have if they are willing to pay the money?” the Supreme Court asked Rohatgi.

Rohatgi responded by saying he was no longer interested in speaking with them. The apex court then ordered the parties to appear in front of the high court on January 31 and requested that the execution application be dismissed without further delay.

“Petitioner’s execution application has been postponed until March 29, 2022.” The HC found that there had been attempts to resolve the issue over payment methods with banks and financial institutions, but these efforts had failed. Therefore, without commenting on either side’s representations, we believe that the hearing on the execution application cannot be further delayed.

In its order, the bench stated that The parties must appear in front of the high court on January 31 and request that the case is heard as soon as possible. Accordingly, we propose that the high court dismiss the execution application without further delay; both the petitioner and respondent will suffer due to the application’s pending status and dismiss DAMEPL’s appeal.

The Delhi High Court had already chastised DAMEPL for playing hide-and-seek with the court and holding out-of-court communications with DMRC to resolve a disagreement over the PSU’s execution of an arbitral award worth over Rs 4,600 crore.

DAMEPL’s argument that the line’s operations were not viable due to structural deficiencies in the bridge over which the train would pass was recognised by the arbitral panel in its May 2017 ruling. DMRC had filed an appeal against a single judge judgement from March 6 last year, upholding the arbitral verdict in DAMEPL’s favour, which a division bench had upheld.

On August 25, 2008, the two parties signed a concession deal. DMRC was to carry out the civil works, except at the depot, and DAMEPL, a joint venture of Rinfra and a Spanish construction company — Construcciones Y Auxiliar De Ferrocarriles — with 95 and 5% shareholdings, was to carry out the remaining works, including the project system works.

After an investment of about Rs 2,885 crore from the DAMEPL promoters’ fund, banks, and financial institutions, the Airport Express line was inaugurated on February 23, 2011.

Resumption of metro services in Chennai, Bangalore and Hyderabad

CHENNAI (Metro Rail News): Thousands of passengers at Wimco Nagar and Chennai Airport will benefit from the project. Hundreds of commuters use the Wimco Nagar suburban railway and Metro stations every day. On the other hand, passengers have always found it challenging to transition from one mode to another since they must walk or take an autorickshaw.

Similarly, numerous travellers and airport employees have requested a buggy service between the terminals and the station at Chennai Airport. According to authorities with the Chennai Metro Rail Limited (CMRL), each station will have two eight-seater vehicles that would run throughout the day.

“We will finalise the contractor shortly, and these vehicles will be available in six months,” an official said. In the increased parking area at Wimco Nagar, there will be a particular lane for these buggies to run between the stations. “Since these vehicles cannot be operated on the road, we will make a separate lane,” the official stated.

Thousands of people exit the station at Vadapalani and proceed to the nearby Forum Mall. They will benefit from this service.
“The largest underground station in the world is the Chennai Central Metro, and many senior folks and others find it difficult to walk from the concourse to the lift point.” “These buggies will only run on the concourse level,” he explained.

BANGALORE (Metro Rail News): By August of this year, the Challaghatta Metro station, which is roughly 2 kilometres from the Kengeri Metro station, will be operational. The Challaghatta station was scheduled to open in March 2022 when the extended Purple Line between Mysuru Road and Kengeri was launched. Ninety per cent of the structural work on this elevated station has been completed, according to senior Bangalore Metro Rail Corporation Limited (BMRCL) officials.

“Along this route, a total of 70 spans have been built, and roof structure construction is currently underway. It will be finished by the end of March. Work on the finishing touches, such as placing stone on the floor, painting, and other outside work, will begin in the first week of February and be completed by July of this year,” a senior official stated.

The official stated that the welding work to join the rails has been completed and that plinths are being installed. “A total of 1,750 metres of rail must be installed, followed by the installation of fixtures around the rails. The power supply third rail will be completed later, “Added the official.

The Baiyappanahalli-Mysuru Road line was extended by 7.5 kilometres up to Kengeri on August 29 of last year. When asked why the delay occurred, an official responded, The most challenging aspect of the project was constructing a 56-meter span above NICE Road.

The second wave of the COVID pandemic, which resulted in a massive labour shortage, further slowed things down. The third wave also has an impact, as many workers are on leave or taking rest due to health concerns.

A small temple stood in the development, causing land acquisition complications. “To finish our work here, we had to finally dismantle it. While the physical work will be completed by July, the inspection and approval by the Commissioner of Metro Rail Safety may take longer. As a result, by the end of August, we’ll be able to run trains here, “added the official.

The Nadaprabhu Kempegowda Layout of the Bangalore Development Authority is also nearby. “An underpass has been suggested to provide communication between Challaghatta station to the layout. BMRCL and the National Highways Authority of India will work together on it. However, it appears improbable that it will be in place at the time of opening of the line.”

AGRA (Metro Rail News): In the last week, Sam India Builtwell achieved two significant milestones on Fatehabad Road’s 4 km Taj East Gate – Taj Mahal Ramp elevated corridor for the Agra Metro Phase 1 project. The final 684 piles for pier foundation construction were installed last week. During a virtual ceremony held by Prime Minister Modi in December 2020, the first ceremonial pile for the 14.25 kilometre Line-1 was drilled.

Then, with the help of Appolo Cranes, Sam’s station team finished installing all 144 double T girders for the platform level of Taj East Gate Station, Basai Station, and Fatehabad Road Station on Sunday. On August 31, 2021, construction on the launch began. Uttar Pradesh Metro Rail Corporation (UPMRC) awarded Sam India Builtwell the Rs. 272.95 crore contract for the 7 km Priority Corridor’s 4 km Package AGCC-01 in October 2020.

Since November 2021, technical offers from seven contractors have been considered for the remaining 3 km underground portion (Package AGCC-02) of the Priority Corridor between Taj Mahal and Jama Masjid stations. However, due to bidding delays, the UPMRC will not be able to complete the 3 km underground section of the Priority Corridor before the 2024 Lok Sabha elections, as planned.

Kothanur Metro depot work to commence soon

BANGALORE (Metro Rail News): The Bangalore Metro Rail Corporation Ltd. (BMRCL) issued a tender notice for the civil construction of the Purple Line’s Challaghatta Depot and Workshop last week. This station will be built on a section of a 40-acre land tract abutting Mysore Road at the southern end of Reach 2B, which is now under construction by Soma Enterprise.

When the old Baiyappanahalli Depot is repurposed to serve the 57 km Blue Line connecting Silkboard – KR Puram – Kempegowda International Airport, Challaghatta Depot, together with the Kadugodi Depot, will become critical in conducting efficient Purple Line operations in the coming years.

Construction of Depot cum Workshop at Challaghatta in Reach-2 Extension of Bangalore Metro Rail Project, Phase-2 is the brief scope. The period estimated for the completion of the project is 2 years with an estimated cost of Rs. 517.44 Cr, and the final submission date would be February 25, 2022, at 3 PM.

STUP Consultants Pvt. Ltd. was granted an Rs. 4.47 crore Detailed Design Consultant (DDC) contract in January 2020. It was supposed to have an Inter Modal Integration Hub (IMIH) at the time, but that has since been dropped. In addition, the depot’s stabling lines were supposed to be on an elevated deck, but that plan was cancelled as well.

The final 1.314 kilometres section of Reach 2B connecting Kengeri Station and Challaghatta Station is expected to open in 2023. The primary priority for BMRCL and their system contractors is to commission the 15.257 km Purple Line Reach 1A & 1B extension to Whitefield, followed by the 3.031 km Green Line Reach 3C extension to Madavar (formerly BIEC). This is the 5th and final depot of the Phase 2 project to be tendered out.

Tender notices for remodelling Baiyappanahalli Depot and constructing Shettigere Depot by Kempegowda Airport are pending for Phases 2A and 2B. The Detailed Design Consultant contract for PADECO Co. Ltd. – Ardanuy India Pvt Ltd. JV was granted in mid-September 2021.

In numerous instances, protests by families who are about to lose their land and homes have hampered the house-by-house survey. As a result, thirty houses will have to be demolished in Payyannur alone. The survey will be conducted in 23 villages in the Kannur district as part of the social impact assessment. In the initial step, surveys would be conducted in 11 villages in the district, ranging from Chirakkal to Payyannur.

In the Kannur district alone, the state government has identified 106.2005 hectares of land for the project. Out of the 530 km rail line from Thiruvananthapuram in the south to Kasaragod in the north, the district would have a 61.7-kilometre segment. The railway line will run through the taluks of Kannur, Payyannur, and Thalassery in the Kannur district.

SilverLine is being hailed as the state’s largest infrastructure project. The journey time between Thiruvananthapuram and Kasaragod is projected to be reduced to roughly four hours. The builder is Kerala Rail Development Corporation Limited (K-Rail). The project is expected to cost more than Rs 63,000 crore.

The number of households to be rehabilitated, the size of the land covered by the project, as well as the number of houses, colonies, and other public areas in the vicinity are all included in the scope of the social impact analysis. The research will also determine whether the land to be purchased is necessary for the project. The cost of compensating for the potential social impact will be calculated during the research.

Over one lakh private vehicles will be replaced by RRTS, reducing CO2 emissions

DELHI (Metro Rail News): The 82-kilometre Rapid Rail Transit Corridor (RRTS) connecting Delhi and Meerut is now under construction, with the 17-kilometre priority section from Ghaziabad to Duhai expected to be completed by 2023. Officials predict that it will reduce CO2 emissions once fully operating by taking about 1.5 lakh private automobiles off the road.

A senior official added that It is anticipated that the corridor will lower total yearly greenhouse gas emissions by 2.5 lakh CO2e, making the city cleaner and a far more excellent place to live. It is also expected to raise the percentage of people who use public transit along the route from 37% to 63%. It will also remove around 1 lakh private automobiles from the road, helping to decongest the NCR, which lacks a public transportation system.

The corridor will run from Sarai Kale Khan in Delhi to Modipuram in Meerut, passing through Ghaziabad. The RRTS, which will be the first of its type in the country, will travel at a speed of 100 km per hour and take commuters to Meerut in 50-60 minutes. Separate business and general coaches will be available on the trains.

The RRTS runs through Delhi for about 14 kilometres, passing through Sarai Kale Khan, Jangpura, Anand Vihar, and New Ashok Nagar. These stations will serve as hubs for Metro stations, ISBTs, and other RRTS corridors.

Of the 14 km stretch, 9.2 km line would be elevated, while the Anand Vihar portion would be underground. “Between New Ashok Nagar and Kondli, foundation work, including piling and pile caps for the elevated section, is in full swing. “A 3-kilometre section is being worked on, with piers being put on portions where foundation work has been finished,” stated a senior NCRTC official.

Work on laying the foundation and pier construction for the Sarai Kale Khan station in Delhi has begun following significant utility shifting/modification. All three RRTS Phase-I corridors – Delhi-Meerut, Delhi-Alwar, and Delhi-SNB – will merge at this station, which will function as an interchange facility for the rapid rail, railway station, metro station, and ISBT.

To get to the railway station or bus stop, people must depart and walk almost a kilometre or take a rickshaw. They will be able to use the interchange facility without having to exit the premises once the RRTS is completed. A four-lane underpass has been built from Mathura Road to the RRTS station in Jangpura to make public access to the station more accessible. Work on the other Delhi stations is also moving very quickly.

The elevated New Ashok Nagar station will provide interchange services with the neighbouring Metro station. According to the official, preparations are underway at Anand Vihar to launch a tunnel boring machine to construct underground portions of the corridor.

In addition, the NCRTC is building a 1.35-kilometre bridge across the Yamuna in Delhi, which will run roughly parallel to the present DND flyway. This will link the RRTS stations of Sarai Kale Khan and New Ashok Nagar. The river bridge will be roughly 626 metres long, with the rest of it being over the khadar area on both sides. It will feature 32 piers with a 44-metre gap between them. The foundation for the bridge is now being laid.

The priority section starting from Sahibabad to Duhai Depot in Ghaziabad will have five stations and are nearing completion. An official exclaimed, “NCRTC has completed about 80% of the foundation work of the elevated section. More than 1,200 piers have been constructed on a 30-km stretch out of 82 km. In addition, about 16-km of the viaduct has been constructed, most of which is located on the priority section.”

ESPO, Finland (Metro Rail News): Nokia stated this week that it would collaborate with Alstom to build a private wireless network for the Delhi to Meerut Regional Rapid Transit System (RRTS) of the National Capital Regional Transport Corporation (NCRTC). In addition, it will enable European Train Control System (ETCS) Level 2 Signaling to ensure commuter safety on the high-speed rail line, which is currently being built.

The Delhi-Meerut RRTS is the first phase of a phased development of a high-speed rail network aimed at enabling sustained economic and social development in Delhi and the neighbouring areas through improved connectivity. The low-emission RRTS, which is expected to be fully operational in 2025, will transport more people at average speeds of 100 kmph, reducing travel time and road congestion.

The fully redundant private network, which will span the 82 km rail route with 25 stations, will be built on Nokia’s Modular Private Wirelesssolution (MPW), which includes the latest AirScale radios, Air Frame-based evolved packet core capabilities, the 7250 IXR IP/MPLS backhaul routers, Group Communication platform for mission-critical push to talk/video (MCx/GC), and Network Services Platform (NSP) management.

The private network will feature ETCS Level 2 and 3 signalling and automated operation (ATO), allowing trains to use radio signals to continuously receive movement authorities and report their exact direction and position to ensure the safety of all passengers on board. For railway operators, introducing LTE/4.9G technology for ETCS is a significant benefit that will pave the way for a smooth transition to FRMCS (Future Railway Communication System).

Chennai Metro is working to minimise noise during metro train riding

CHENNAI (Metro Rail News): Many commuters may have experienced a screeching noise in metro trains, generated mainly by train-track friction, which frequently occurs on tight curves. The Chennai Metro Rail Limited (CMRL) will shortly commence track maintenance, including the use of rail grinding equipment to smooth out rails worn down by train operations, minimise noise, and increase the life of the rails.

According to a metro rail official, work would be completed in 90 days over the 54-kilometre line from Wimco Nagar to Airport and from Central Metro to St Thomas Mount. “We’ll probably start working in February.” According to the official, the work will be done between midnight and 4.30 a.m.

“The grinding will improve rail-wheel interaction in addition to lowering noise,” the official stated. According to officials, the rail grinding machine, which resembles a diesel locomotive, is expected to be rented from the Bangaluru metro and operated by a foreign specialist. CMRL has issued a tender for the machine’s transportation, loading, and unloading.

Due to friction produced by train movements and exposure to the environment, the ballastless rails experience corrugation and in some cases, corrosion. This frequently results in rail squeals, a screeching noise made by trains as they navigate sharp curves or straight stretches, as well as shocks and vibrations.

As a result, the rails must be ground regularly. Rail grinding began shortly after its establishment in 2015, and it will continue in 2019, 2020, and 2021. “The primary concern that occurs from failing to grind the rails is the harm that the undulation and pit marks on the train wheels may cause.”

“The rails are constructed of hard steel, while the train wheels are made of soft steel, both of which are imported from Europe and are costly to replace if they are broken,” one official explained. With the 118.9 km phase-2 taking shape, CMRL officials said a procurement process for rail grinding equipment has begun, which might cost roughly Rs 50 crore and take nearly 2.5 years to complete.
