By the end of next year, no four-coach train will run on Delhi Metro's Line 2 and Line 3/4. Only six coach and eight coach trains will run on the two longest and busiest corridors.
DMRC chief Mangu Singh said on Line 2 (Jahangirpuri-Gurgaon), of a total of 60 trains, more than 50% will be converted to eight coach trains, while remaining will be six coach trains. Similarly, on Line 3/ 4 (Dwarka-Noida/ Vaishali), of the 71 trains 50% would be converted to eight coach trains, while the rest will be six coach trains.
By June 2015, all trains plying on Line 3/4 will be eight coach trains and also all four-coach trains plying on Line 1 will be converted to six-coach trains.
Singh said the new coaches will start arriving next month immediately after which eight coach trains will be introduced.
To ensure commuters' convenience, Delhi Metro has also decided to change the signalling system in the stations so that the first coach stops at a single point.
