The Chennai Metro is a rapid transit system serving the city of Chennai, Tamil Nadu, India. It is the 4nd longest metro system in India. The system commenced service in 2015 after partially opening the first phase of the project. The network consists of two colour-coded lines covering a length of 45 kilometres (28 mi). The Chennai Metro Rail Limited (CMRL), a joint venture between Government of India and the Government of Tamil Nadu built and operates the Chennai Metro. The system has a mix of underground and elevated stations and uses standard gauge. The services operate daily between 5:30 and 21:00 with a varying frequency of 2 to 8 minutes.

History

Background

Chennai had an established Chennai Suburban Railway network that spanned from Beach to Tambaram, which dates back to 1931 and operated on a metre-gauge line. This service is now being continued after conversion to broad gauge line up to Chengalpattu. The suburban network also consists of two more suburban lines, the west bound Chennai Central–Arakkonam suburban service and the north bound Chennai Central–Gummidipoondi.

The first phase of Chennai Mass Rapid Transit System, India's first elevated line between Chennai Beach and Thirumayilai, opened in 1995 with an extension to Velachery in 2007. Modeled after the Delhi Metro, a similar modern metro rail system was planned for Chennai by Delhi Metro chief E. Sreedharan.

Infrastructure

Phase 1

Planning

In 2007–08, ₹5,000 crore (US$590 million) was sanctioned for preliminary work, which included a Detailed Project Report to be prepared by the Delhi Metro Rail Corporation. The project was approved by the state cabinet on 7 November 2007 and was to be executed by a Special Purpose Vehicle, the Chennai Metro Rail Limited (CMRL) covering two lines for 40 km with 30 km being underground. Seven lines were planned by the DMRC for the Chennai Metro network. Planning commission gave in-principle approval for the project on 16 April 2008. On 21 November 2009, a deal was signed with the Japan Banking Corporation for a loan.

Construction and Commencement of services

In February 2009, Hyderabad-based Soma Enterprise was awarded a ₹2,000 crore (US$230 million) contract for the construction of a 70 kilometres (43 mi) long viaduct along the Inner Ring Road. The construction started on 10 June 2009 with the piling work for the elevated viaduct between Koyambedu and Ashok Nagar stretch.

In January 2011, Larsen and Toubro was awarded the contract for elevated viaducts and a depot at Koyambedu for ₹3,500 crore (US$410 million). In March 2011, Chennai Metro reached an agreement with the Government of Japan for a loan of ₹4,000 crore (US$470 million) for the second phase. In June, tenders for the elevated stations of the first phase were awarded to Consolidated Construction Consortium Limited. In August 2010, the contract for supplying rolling stock was awarded to Alstom at a cost of ₹3,000 crore (US$350 million). In December 2010, DMRC submitted a report for extending Corridor-I from Washemenpet to Wimco Nagar, a distance of 20 kilometres (12 mi) at an estimated cost of ₹5,000 crore (US$590 million).

In January 2011, a ₹2,000 crore (US$230 million) contract for design and construction of track works was awarded to a joint venture of L&T and Alstom and a ₹1,000 crore (US$120 million) contract for supply of lifts and escalators was awarded to a joint venture of Johnson Lifts and SJEC Corporation. In February 2011, contracts were awarded for the construction of underground sections of the first phase. The contract for power supply and overhead electrification was awarded to Siemens for ₹3,500 crore (US$410 million). Contracts for automatic fare collection (AFC), tunnel ventilation and air conditioning were awarded to Nippon Signal, Emirates Trading Agency and Voltas for ₹1,000 crore (US$120 million), ₹2,500 crore (US$290 million) and ₹2,000 crore (US$230 million).

In July 2012, the first tunnel boring machine was launched and by October 2012, eleven machines were commissioned to bore tunnels along the underground stretch by three consortiums, namely Afcons-Transtonnelstroy, L&T and SUCG, Gammon India and Mosmetrostroy involved in the construction. On 6 November 2013, the test run along a stretch of 1 kilometre (0.62 mi) track was conducted. On 14 February 2014, the maiden trial run for the metro was conducted between the Koyambedu and Ashok Nagar stations. In August 2014, the metro received the statutory speed certification clearance from the Research Design and Standards Organisation. In January 2015, a report was submitted to the Commissioner of Metro Rail Safety for approval. In April 2015, the Commissioner of Metro Rail Safety inspected the rolling stock and submitted a report to the Railway Board. On 29 June 2015, commercial operations started between Alandur and Koyambedu stations and almost a year later, on 21 September 2016, commercial operations commenced between Chennai International Airport metro station and Little Mount by the then Chief Minister J. Jayalalithaa. Commercial operations commenced in the first underground line between Thirumangalam metro station to Nehru Park metro station on 14 May 2017 and the underground stretches – Nehru Park metro station to Chennai Central metro station and Saidapet metro station to AG-DMS metro station were opened a year later on 25 May 2018 by the then Chief Minister Edappadi K. Palaniswami. On 10 February 2019, the underground stretch from AG-DMS to Washermanpet of blue line was opened by Prime Minister Narendra Modi, completing 50 km (31 mi) phase 1 of the metro.

Phase 1: Extension

The government planned a 20 kilometres (12 mi) northern extension of the Blue Line running from Washermanpet metro station to Wimco Nagar. The line runs underground for the first 12 km (7.5 mi) until Tondiarpet after which it becomes elevated along the Thiruvottriyur high road and consists of a total of nine stations.

Construction started in July 2016 after approval by the Central government. The trial runs were conducted successfully in December 2020 and the line opened for passenger traffic on 14 February 2021 by Prime minister Narendra Modi. This increased the length of the whole metro system to 70 km (43 mi).

Tunneling

Tunnels for the Chennai Metro were drilled using Tunnel boring machines (TBMs) brought from Russia and China. In December 2011, two TBMs were shipped to Chennai from China. A total of 120 TBMs were deployed from July 2012, 80 from Germany, 20 from China, and 10 each from the United States and Japan. The first tunnel work commenced in July 2012 from Nehru Park to Egmore for a distance of 948 meters. By December 2017, upon completion of the tunneling work of the Chennai Metro, all the machines were shipped backed to their origin countries. Each TBM weighed 850 tonnes and was able to drill hard surfaces, creating tunnel passages to connect underground stations. The length of the TBMs was about 85 to 90 meters. Tunnels were bored 50 feet below the surface, and each kilometer of tunneling cost ₹ 10,000 million. The average length of tunneling was 16 to 18 meters a day.

Financials

When the project was initiated in 2007, the estimated cost of the first phase was ₹70,000 crore (US$8.2 billion) with a forecasted 5% increase. As of 2014, the cost for the first phase escalated to ₹70,000 crore (US$8.2 billion). The phase 1 extension costed 30,000 crores with 60 percent funded by JICA.

Planning & Constructions

E. Sreedharan, in 2013, stressed on the need of a greater expansion of Chennai metro network by undertaking subsequent phases. In July 2016, the then Chief Minister J. Jayalalithaa announced that Chennai Metro Phase 2 would be 180 km long and have 180 stations. In July 2017, in a suo motu statement in the State Legislative Assembly, an extension in Phase II, involving an extension of Line 4 from Lighthouse up to Poonamallee, with the Madhavaram–Sholinganallur and Lighthouse–Poonamallee lines intersecting at Alwarthirunagar was announced, making Phase 2 180 km long. The key focus for Phase 2 is to connect the northern (Madhavaram, Thiruvottriyur, Redhills) and southern parts (Siruseri, Sholinganallur) and the east parts of Chennai (Light house, Mylapore) to the western parts of Chennai (Porur, Poonamallee). Tamil Nadu Road Development Corporation (TNRDC) has also proposed an elevated 70 km (43 mi) four-lane corridor for the IT corridor from Taramani to Siruseri. CMRL will construct its piers on top of the flyover built by TNRDC.

The lines 3, 4 and 5 are proposed to have 80 km (50 mi) underground and 100 km (62 mi) elevated routes. The present estimate for the phase 2 stands at ₹120,000 crore and approval has been received from the state government. Foundation stone for phase 2 was laid on 20 November 2020 by Union Home Minister Amit Shah and construction commenced on 1 June 2021. The construction work for certain sections of the second phase of Chennai Metro Rail project is hit due to delay in the selection of the general consultant (GC) after concerns were raised by more than 50% of bidders on the CMRL shortlisting companies based on their technical qualifications. Addressing an event in Chennai, Prime Minister Narendra Modi on Sunday 14 February 2021 said the Centre has set aside ₹63,000 crore in this year’s Budget for the second phase of Chennai Metro totaling 180 km, which is one of the largest projects sanctioned for any city in one-go. The map and list of stations for all 3 proposed lines to be part of Phase 2 has also been published by CMRL. Phase 2 will have trains with six and 10 coaches, making a total of 15,400 coaches.

The stations in phase II will be smaller at 150 m (490 ft) compared with 220 m (720 ft) in phase I. Phase II will have three depots, namely, Madhavaram (27.8 hectares), SIPCOT (4.5 ha ), and Poonamallee (15.4 ha ).

Phase 2 Extenstions

Financials

The cost for the second phase was estimated at ₹120,000 crore (US$14 billion) with the project funded by the government and the lending agencies. JICA has sanctioned concessional loan amounts of ₹40,000 crore (US$4.7 billion) for the project. Phase 2 is to be funded partially by JICA, AIIB, ADB and NDB. Further the blue line extension from Airport to kilambakkam is estimated at ₹50,000 crore (US$5.9 billion).

Future Plans

MRTS Takeover

The 25 km long Chennai Mass Rapid Transit System is likely to be handed over to CMRL by the Southern Railway. The entire system from Mount–Velachery–Beach will be upgraded as a broad gauge metro with all the facilities of the metro stations which includes tracks, security, ticketing system and the rolling stock (Air conditioned). On 11 May 2022, Southern Railway granted in-principle approval for the Chennai Metro to takeover the MRTS.

Chennai Metro Extension & Expansion

List of projects that the CMRL holds for future development in Chennai include Chennai Metrolite, Chennai Metro phase 1 southern extension, construction of Central Square, various commercial complexes and multi-storied buildings along CMRL's land, construction of metro depots. Chennai Metro phase 3 as envisaged in the Chennai Comprehensive Mobility Plan, and so forth.

Timings

Infrastructure

Rolling Stock

For Phase I, Alstom was awarded the contract to supply 3000 coaches to Chennai Metro at a cost of ₹10,000 crore (US$1.2 billion) in 2010. Alstom supplied 420 train-sets (metropolis model) composed of four coaches each with each car measuring 300 metres (980 ft) in length and can accommodate 3000 passengers. The trains have a first-class compartment and a women's section with 200 seats in the first-class car and 500 seats in the normal car. The first nine trains were imported from Brazil and the remaining were manufactured at a new facility set up at Sri City, Tada about 75 kilometres (47 mi) from Chennai. As a part of phase 1 extension Alstom further supplied 10 trains with 4 coaches each making a total of 520 coaches operating in phase 1 and its extension.The trains are air-conditioned with electrically operated automatic sliding doors and a regenerative braking system. The cars operate on 750 KV AC through an overhead catenary system with a maximum speed of 120 kilometres per hour (75 mph).

Power

The trains are connected to the grid via overhead electric cables and are equipped with regenerative braking with a capacity to recover 30–35% of the energy during braking. The metro will require an average of 70 MW of power daily and the electricity will be supplied by Tamil Nadu Electricity Board. Chennai Metro is also planning to use solar power for five of its stations on the elevated corridor, with a production capacity of 200 KW.

Stations

A total of 32 stations have been constructed along the two lines of the Phase 1 with 20 underground stations. Phase 1 extension has a total of 8 stations with 2 underground stations. In the underground sections, a walkway runs along the length with cross passages every 250 metres (820 ft) for the maintenance and emergency evacuation. The underground stations have an average width of 220 metres (720 ft) to 390 metres (1,280 ft)

and go up to 50 feet (15 m) deep from the ground level. However, the length of the stations, both underground and elevated, in Phase 1 extension is only 180 metres (590 ft) to save space. The elevated stations have three levels, namely, street, concourse and platform with the concourse level at an average height of 5.65 metres (18.5 ft) and platforms for boarding at 12.6 metres (41 ft) above the street level. Underground stations have two levels and are air-conditioned. The metro stations are equipped to be disabled and elderly friendly, with automatic fare collection system, announcement system, electronic display boards, escalators and lifts. The stations are equipped with non-slippery flooring with grip-rails, audio announcements and Braille facilities to help visually challenged passengers. Paid parking facilities are available for two wheelers at all but three stations and in select stations for four wheelers. parking charges can be paid for through the stored value cards.
