The upgradation of power supply on the western line is expected to be complete by June this year. The power conversion would mean that the flow of electricity supply to trains would improve, making their run smoother, faster and consume less electricity. This would also mean removal of the remaining old trains, which run on DC power supply.
Kul Bhushan, general manager, Central Railway who also holds charge of the Western Railway, said, "Our first priority would be conversion from DC to AC till Churchgate. We would then convert all trains from nine-car to 12-car."
A nine-car train carries around 4,100 commuters during peak hours. Of the total 76 trains on the WR, there are 14 nine-car trains, one 15-car train and remaining 12-car trains. There are 11 nine-car trains on the main line of the CR while there are 35 nine-car trains on the Harbour line and four trains on the Trans-Harbour line.
