Planning and construction

edit

Phase I

edit

In 2006, a modern metro rail system was planned for Chennai modeled after the Delhi Metro.[1][2] Delhi Metro Rail Corporation (DMRC) was tasked with preparing a detailed project report on the implementation of metro system in Chennai.[2] Based on the report, the Government of Tamil Nadu approved the first phase of the project in November 2007.[3] The first phase was planned with two lines covering 45.1 km (28.0 mi) with 25 km (16 mi) being underground. The first corridor would connect Washermanpet with Chennai International Airport extending for 23.1 km (14.4 mi) with 14.3 km (8.9 mi) being underground.[2] In December 2007, Chennai Metro Rail Limited (CMRL) was incorporated and the Government of India gave approval for the project in January 2009.[4][3]

The construction started in June 2009.[5] In August 2010, the contract for supplying rolling stock was awarded to Alstom.[6][7] Test and trial runs happened on the Green line in 2013 and early 2014.[8][9][10] After approvals from RDSO and the Commissioner of Metro Rail Safety, commercial operations started between Alandur and Koyambedu stations on the green line in June 2015.[11][12][13] On 21 September 2016, commercial operations commenced between Airport and Little Mount on the blue line.[14] In May 2018, the blue line was extended between Saidapet and AG-DMS.[15] On 10 February 2019, the underground stretch from AG-DMS to Washermanpet of blue line was opened, completing the first phase of the metro.[16]

The trains are operated on 1,435 mm (4 ft 8+1⁄2 in) standard gauge double-tracked lines.[25] The average speed of operation is 85 kilometres per hour (53 mph) and maximum speed is 120 kilometres per hour (75 mph).[26] Alstom supplies the rolling stock for the trains operated on the line.[27] The trains are air-conditioned with electrically operated automatic sliding doors and have a first-class compartment with a dedicated section reserved for women.[28]

The trains operate on 25 kV AC traction catenary system.[29] 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.[30] The electricity is supplied by Tamil Nadu Electricity Board.[31]

A total of 26 stations are operational along the blue line with 13 underground stations.
