## History

The first passenger train in India from Chhatrapati Shivaji Terminus in Mumbai to Thane ran on 16 April 1853 on the track laid by the Great Indian Peninsula Railway. The GIPR line was extended to Kalyan in 1854 and then on the north-east side to Igatpuri and the south-east side to Khopoli via Palasdari railway station at the foot of the Western Ghats in 1856.

## Electrification

Railway electrification in India began with the first electric train, between Bombay Victoria Terminus and Kurla by the Great Indian Peninsula Railway (GIPR) on 3 February 1925, on 1.5 kV DC. The Kalyan–Pune section was electrified with 1.5 kV DC overhead system in 1930.
The previously used 1.5 kV DC was converted to 25 kV AC on 5 May 2013 from Kalyan to Khopoli and Kalyan to Kasara. Conversion from 1.5 kV DC to 25 kV AC on the Lokmanya Tilak Terminus-Thane-Kalyan section was completed on 12 January 2014. The CSMT to LTT section was converted from 1.5 kV DC to 25 kV AC on 8 June 2015.

## Services

Since November 2011, all services on the Central line have been running on 12 cars. In preparation for introducing 15 car services, CR extended platforms at Byculla, Kurla, Ghatkopar, Bhandup, Mulund and Dombivli stations, from the current 270 metres to 330 metres, in order to accommodate 15 coach trains. The total cost of the work was estimated at ₹37.5 million (US$430,000). The first 15-car service, on the Central line, departed from Chhatrapati Shivaji Terminus to Kalyan at 7:33 pm on 16 October 2012.
As of March 2014, 75 rakes operate 825 services on the Central line daily, of which 809 are 12-car and 16 are 15-car services.
