The Chennai Metro (Tamil: சென்னை மெட்ரோ) is a rapid transit system in Chennai, Tamil Nadu, India. The Phase I of the project consisting of two corridors is under construction. The elevated section of the project is scheduled to be operational by 2013 and the entire project is scheduled to be completed by the financial year 2014-2015. About 55% of the corridors in Phase I is underground and the remaining elevated.
Background
Chennai is the 4th largest metropolitan city in India. Chennai often known as the Detroit of Asia is widely known for its presence in the automotive industry and has attracted several global automakers to setup their factories in the city becoming one of the global leaders in the industry. Apart from automobiles, it also has development centres set up by many software companies which contributed 14% of India's total software exports of ₹144,214 crore (US$17 billion) during 2006–07, making it the second-largest exporter of software in the country, behind Bangalore. Based on all these industrial and technological advancements, urban population has risen rapidly, requiring need for faster and safer transportation at all times. The city already has multiple modes of transportation. A bus system is run by the Chennai MTC and is augmented by the Chennai suburban railway network run by the Southern Railway. In addition to this, the Chennai Corporation has also implemented the Chennai MRTS project, an elevated railway system was sanctioned in 1984 to ease congestion in central Chennai. However, traffic congestion was still a big problem for both the citizens as well as the City's governing body. Hence, the Chennai Corporation has decided to implement the Chennai Metro project which will be another alternate transportation mode to a metropolis like Chennai. Mr K.Rajaraman IAS, 1989 Batch Officer of Tamil Nadu cadre is the Managing Director of CMRL.
History
After the success of the Delhi metro, a similar system was mooted for the city of Chennai by E. Sreedharan of the DMRC to the then Chief Minister of Tamil Nadu J. Jayalalitha.[2] The plan was later dropped in favour of a highly ambitious monorail network, spread over the whole city.[3] After being voted out of power soon after, the new CM M. Karunanidhi revived the metro rail project to life once again.
The Metro rail project was included in the 2007-08 State Government's budget, and an amount of 50 crores had been sanctioned for preliminary works which included a Detailed Project Report (DPR) to be prepared by the DMRCRail Project. The approval for the project was finally given by the state cabinet on 7 November 2007[4] and is to be executed by a Special purpose vehicle, the Chennai Metro Rail Limited (CMRL).
Corridors
Master Plan prepared by DMRC
A Total of 7 lines have been planned by the DMRC for Chennai Metro Rail Project.[5]
Line | Termini | Opening Date | Length (km) |
Underground (km) |
Underground stations |

---|---|---|---|---|---|---|---|---|
Line 1 | Tiruvottiyur | Chennai International Airport | 2014 | 32.1 | 14.3 | 11 | 6 | Suburban, MRTS, 2 |
Line 2 | Chennai Central | St. Thomas Mount | 2013 | 22 | 9.7 | 9 | 8 | Suburban, MRTS, 1 |

Corridors proposed in CTS
Two corridors have been proposed in the comprehensive transportation study recently submitted by Wilbur Smith Associates.[6]
Corridor 1: Medavakkam — St. Thomas Mount
Corridor 2: Madhavaram — Lighthouse via Radhakrishnan Salai
Corridors proposed by CMRL
A metro line from Thiruvanmiyur — 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 it for present and take it up later. This was proposed as an alternate for the East Coast Elevated Expressway[7]
Projects in Study
A project study would be taken up to establish links between Moolakadai--Thirumangalam, Moolakadai--Thiruvanmiyur and Luz—Poonamallee through Iyyappanthangal.[8]
Others
Apart from these, there are demands to extend the Metro Rail to Tambaram.[9] State Government is considering extension to Tambaram.[10]
Proposed MRTS take-over by CMRL
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 very poorly executed project and is a loss making enterprise at present. After the merger, it is proposed to replace the current EMUs in the MRTS with air-conditioned coaches with automatic doors.[11]
Phase I
According to the Detailed project report submitted by the DMRC, there are two lines planned:
Line | Termini | Opening Date | Length (km) |
Underground (km) |
Underground stations |
Elevated stations |
Rakes | # of Coaches | Interchange | |
---|---|---|---|---|---|---|---|---|---|---|
Line 1 | Washermanpet | Chennai International Airport | 2014 | 23.1 | 14.3 | 11 | 6 | 23 | 92 | Suburban, MRTS, 2 |
Line 1 Extension | Wimco Nagar | Washermanpet | 2015 | 9 | 2.3 | 1 | 6 | North, West North, West South | ||
Line 2 | Chennai Central | St. Thomas Mount | 2013 | 22 | 9.7 | 9 | 8 | 23 | 92 | Suburban, MRTS, 1 |
- The Corridor 1 is being extended from Washermapet to Thiruvottiyur as it was originally planned. A detailed investigation is being under taken by the announcement of Governor of Tamil Nadu.[12]
- DMRC conducts soil tests in Thiruvottiyur areas for Metro extension.
Cost
The project is estimated to cost around ₹14,600 crore (US$1.7 billion) for the two corridors totaling 45 km. However, the previous estimate in 2007 was ₹9,565 crore (US$1.1 billion).[13] But it is likely to increase by 23% to ₹18,000 crore (US$2.2 billion)[14] The Underground tunneling will cost about Rs 300 crores per km, whereas Elevated track will cost about Rs 100 crores per km. The estimated construction cost of Underground and Elevated Station will be Rs 100 crores and Rs 300 crores respectively.[15]
Finance
The central government has agreed to partly finance the project, similar to the aid extended to the Bangalore metro and Hyderabad Metro.[16] This is in addition to the funds provided by the state government. The JBIC is also expected to fund the project.
Stations
A total of 32 stations have been planned along the two corridors. 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.
Corridor 1
Underground Stations (12):Sathiyamoorthy Nagar,Tiruvottiyur, Washermanpet, Mannadi, High Court, Chennai Central, Tamil Nadu Legislative Assembly, LIC, Thousand Lights, Gemini, Teynampet, and Saidapet
Elevated Stations (6): Little Mount, Guindy, Alandur, Officer's Training Academy, Meenambakkam and Chennai International Airport.
Corridor 2
Underground Stations (9): Chennai Central (Interchange), Egmore, Nehru Park, Kilpauk Medical College, Pachaiyappa's College, Shenoy Nagar, Anna Nagar East, Anna Nagar Tower and Tirumangalam.
Elevated Stations (8): Koyambedu, CMBT, Arumbakkam, Vadapalani, Ashok Nagar-KK Nagar, SIDCO, Alandur (Interchange) and St. Thomas Mount (Parangimalai)
Inter Modal transit facilities
The metro corridors would provide connection with various other transport systems in the city:
- 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.
