Chennai is the fourth largest metropolitan city in India. In recent years, the population has risen rapidly and thus required the need for reliable and safe transportation. Currently, the city already has multiple modes of transportation including an extensive bus system run by the Chennai MTC. The transportation network is augmented by the Chennai suburban railway network run by the Southern Railway. Furthermore, the Southern Railway runs the Chennai Mass Rapid Transit System, an elevated metropolitan railway system was sanctioned in 1984 to relieve congestion in central Chennai. Despite the improvement measures that were made, traffic congestion has continued to be an issue for both the residents and the city government. As a result, the Chennai Corporation has decided to implement the Chennai Metro project which will provide another mode of transportation for Chennai. Mr K.Rajaraman IAS, 1989 Batch Officer of Tamil Nadu Cadre has been named as the Managing Director of CMRL.
After the success of the Delhi Metro, a similar system has been planned for the city of Chennai by E. Sreedharan of the DMRC to the then Chief Minister of Tamil Nadu Karunanidhi. The plan was later dropped in favour of a highly ambitious monorail network, spread over the whole city during Jayalalitha's tenure. Karunanidhi revived the metro rail project to life once again by including it in the 2007-08 State Government's budget, and an amount of 500 million had been sanctioned for preliminary works which included a Detailed Project Report (DPR) to be prepared by the DMRC Rail Project. The approval for the project was finally given by the state cabinet on 7 November 2007 and is to be executed by a special purpose vehicle, the Chennai Metro Rail Limited (CMRL).
A total of 7 lines have been planned by the DMRC for the Chennai Metro network. Two routes are currently under construction as part of the first phase, with several planned for future phases of the metro network.
|Line 1||Tiruvottiyur||Chennai International Airport||2014||32.1||14.3||11||6||Suburban, MRTS, 2|
|Line 2||Chennai Central||St. Thomas Mount||2014||22||9.7||9||8||Suburban, MRTS, 1|
|Line 3||Mogappair||Tiruvanmiyur||24||10||9||8||4, MRTS|
|Line 4||Porur||Kamarajar Salai||3|
|Line 5||Ring Road||Ring Road|
|Line 6||Radhakrishnan Salai||Kilpauk Medical College||2|
|Line 7||Along NH5 Road||Along NH5 Road|
Several studies and proposals have been made to identify new lines to augment the two lines currently under construction. Two lines have been proposed in the comprehensive transportation study submitted by Wilbur Smith Associates  from Medavakkam to St. Thomas Mount and Pattinambakkam to Lighthouse via Radhakrishnan Salai. A metro line from Thiruvanmiyur to Kottivakkam and beyond via ECR has been proposed by CMRL in the steering committee meeting of the Department of Highways and Minor Ports. But it has been decided to defer construction for the present and resume later. This was proposed as an alternate for the East Coast Elevated Expressway A project study was produced to establish links between Moolakadai and Thirumangalam, Moolakadai and Thiruvanmiyur and Luz and Poonamallee through Iyyappanthangal.
The construction started on 10 June 2009 with the piling work for the elevated viaduct between Koyambedu and Ashok Nagar stretch. Construction is expected to be fully completed by February 2015. The first section to be opened will be on Line 2 between Koyambedu and St. Thomas Mount and this stretch is likely to be in operation by 2013. The construction work on the project was suspended on 9 August 2012, following an accident that killed a worker and injured six others, a day earlier. The work resumed after safety audit across its 32 stations was completed.
The project is estimated to cost around 146 billion (US$2.2 billion) for the two corridors totaling 45 km. However, the previous estimate in 2007 was 95.65 billion (US$1.5 billion). But it is likely to increase by 23% to 180 billion (US$2.8 billion) The Underground tunneling will cost about Rs3 billion per km, whereas Elevated track will cost about Rs1 billion per km. The estimated construction cost of Underground and Elevated Station will be Rs1 billion and Rs3 billion respectively.

Alstom won its first metro rolling stock contract in India to supply 168 cars and 16 additional metro cars to Chennai Metro for €243 million. Alstom will supply Chennai metro's public operator with 42 train-sets composed of four cars each. Each coach costs CMRL Rs.90 million. The stainless steel trains will feature air-conditioned interiors and electrically operated automatic sliding doors, offering comfort and easy access to passengers. They will be equipped with a regenerative braking system ensuring significant energy savings. The cars will operate on 25 KV AC through an overhead catenary system at speeds of up to 80 km/h. The first coach from Alstom Transport for the Chennai Metro Rail project is expected to be launched from the Sri City Special Economic Zone by April 2013. Alstom Transport has set up a metro car manufacturing unit at Sri City SEZ at Tada, Andhra Pradesh, about 90 km from Chennai.
The initial frequency will be every 4.5 minutes in peak hours and every 15 minutes in lean hours, when the Metro Rail is inaugurated. CMRL is planning to increase the frequency to one train every 2.5 minutes once footfalls reach 600,000 passengers a day. The train will have an average speed of 34 km per hour and will halt at every station for about 30 seconds.
Each 4-car train will have a carrying capacity of 1,276 people and each 6-car train can carry 1,580 people. A single trip in a 4-car train is equivalent to a ride in 16 buses, 300 cars, and 600 two-wheelers. By 2016, the number of passengers using the service during peak hours is expected to be around 24,968 in corridor I and 24,324 in corridor II.
Upon its opening, the Chennai Metro is slated to adopt a fare based ticketing structure. The following table is an approximate table for what the preliminary fare scheme will be:
|Distance (km)||Metro Fare ()|
|0 - 2||8.00|
|2 - 4||10.00|
|4 - 6||11.00|
|6 - 9||14.00|
|9 - 12||15.00|
|12 - 15||17.00|
|15 - 18||18.00|
|18 - 21||19.00|
|21 - 24||20.00|
|24 - 27||22.00|
The first car in each train will be first class with tickets costing twice as much as the second class tickets.
A total of 41 stations have been planned along the two lines. As many as 19 stations are underground and 12 are elevated. Of these, the Chennai Central (underground) and Alandur (elevated) are common for both the corridors and serve as interchange stations.
All metro stations are being constructed as disabled friendly and elderly friendly, with automatic fare collection system, automatic announcement system, electronic information display boards, escalators, lifts, and toilets. Elevated stations will have shopping malls and parking space, with additional space for future growth. Wi-Fi facility is also being planned at some of the stations. Underground stations will be air-conditioned and will have boosters to amp up cellphone signals within the premises.
Underground stations will have two levels, namely, a platform level and a concourse level. A mezzazine (additional level) in between the two has been planned where the depth of the station is greater. Platform level of the stations will have space for the commuters to assemble during normal operations, delays and emergency situation. The concourse level will be divided into paid and unpaid area and will also house an automatic fare collection system. The unpaid area provides the commuters with facilities such as access to the station, travel information and tickets counters. Automatic ticket gates with scanners provide access to the platforms, which is a common feature at underground and elevated stations.
The elevated stations will have three levels, namely, street, concourse and platform. Street level of the stations will have entry and exit, service rooms for diesel generators and transformers. Concourse level of the stations will be over 5.65 metres above the street level and will have station control room, ticketing counters, ticket gates. The platform for boarding trains will be around 12.6 meters above the street level.
Of the stations, Chennai Central, spread over 70,000 sq m, will be the largest, followed by St. Thomas Mount, Shenoy Nagar, Gemini and Washermenpet. SIDCO station in Guindy will be the smallest. The Chennai Central metro station is being constructed at a depth of 25 metres and will serve as a nerve centre since the both the corridors of the Metro Rail project converge in the station. St. Thomas Mount station, where MRTS and suburban lines meet, will be the second largest metro station in the city, where metro line and MRTS line will meet at two levels. A separate pathway is being provided for commuters from suburban railway station to walk into the Metro-MRTS station complex.
Parking facilities will be available only in some of the stations, including Chennai Central, Chennai Airport, Alandur, and Washermenpet, while others may not have parking provision due to lack of space.
Completed in job level is completed. in 05.08.2013
The metro system will provide connections with various other transportation modes in the city. They are listed below at the proposed station site:
- Chennai Suburban Railway network: Washermanpet, Chennai Fort, Chennai Park, Chennai Central, Chennai Egmore, Guindy, Meenambakkam and St Thomas Mount.
- Chennai MRTS: Chennai Fort, Park Town and St Thomas Mount.
- Chennai Metropolitan Transport Corporation bus terminuses: Broadway bus terminus, Chennai Central, Chennai Egmore, Anna Nagar, CMBT, Vadapalani, Ashok Nagar, DMS, Saidapet, Guindy and St. Thomas Mount.

- State Express Transport Corporation (Tamil Nadu): CMBT.
- Tamil Nadu State Transport Corporation: CMBT, Vadapalani and Guindy.
- Chennai Contract Carriage Bus Terminus: Koyambedu.
|Chennai Metro Phase II|
Three lines covering a distance of 63 kilometres  have been proposed in the second phase of the network. A detailed project report is to be prepared in a year regarding feasibility of the proposed lines.
Line 3 is envisioned to be a 19 kilometre route with 15 stations from Moolakadai to Thiruvanmiyur. Stations are currently planned at: Moolakadai, Madhavaram, Retteri Junction, Villivakkam Railway Station, Periyar Nagar Bus Terminus, Venus, Perambur, Aynavaram Bus Terminus, Kellys, Purasaiwalkam, KMC Hospital, Egmore, Thousand Lights, Mylapore and Thiruvanmiyur.
This is not yet Confirmed.
Line 4 is envisioned to be a 22 kilometre route with 8 stations from Moolakadai to Thirumangalam Junction. Stations are currently planned at: Moolakadai,Vinayagapuram/Teachers Colony, Surapet, Redhills, Ambattur OT, Maduravoyil Junction,MMM Hospital and Thirumangalam Junction
Line 5 is also envisioned to be a 22 kilometre route with 8 stations from Mylapore to Poonamallee. Stations are currently planned at: Mylapore, Luz, Teynampet, T Nagar, Vadapalani, Saligramam, Iyyapanthangal and Poonamallee
Takeover of MRTS
The MRTS, operated by Southern Railway, is proposed to be taken over by the CMRL thereby bringing all the elevated tracks and underground tracks inside the city under one organization. The Chennai MRTS is a well executed project and is a fully public service oriented enterprise at present. After the merger, it is proposed to replace the current EMUs in the MRTS with air-conditioned coaches with automatic doors.
Parks taken over for construction
As of 2011, four urban parks in the city has been taken over by CMRL for construction-related activities. These have been closed to the public since then. They include Corporation parks at Ashok Nagar, Thiru-Vi-Ka Park in Shenoy Nagar, Nehru Park on Poonamallee High Road, and May Day Park in Chintadripet. At the Ashok Nagar Park, the pillars of the elevated corridor would come up on the edge of the park to provide sufficient turning radius.
Upon completion of the construction work, all the four parks will be renovated at a cost of 20 million.
