Central line (Mumbai Suburban Railway)


The Central line of the Mumbai Suburban Railway is a public transit system serving Mumbai, Maharashtra, India. It consists of 24 stations from Chhatrapati Shivaji Maharaj Terminus to Kalyan Junction. The entire line is at grade. It has section of quadruple track starting from Chhatrapati Shivaji Maharaj Terminus and ends at Kasara, Roha, Uran and Khopoli in Maharashtra.
The Central line in Mumbai consists of three major corridors, which bifurcate as they run into suburban satellite towns.
Two corridors on Central Railway run from CSMT to Kalyan Junction, from where it bifurcates into two lines – one running up to Kasara in the north-east and the other running up to Khopoli in the south-east. These two corridors constitute the 'Main' Line. The Central main line shares one station with the Western line at Dadar. They consist of a fleet of DC as well as dual-powered EMUs.
The major car sheds on this line are at Kurla and Kalva. There are fast and slow locals here for suburban service. Slow locals halt at every station, while fast locals halts vary between Byculla, Dadar, Kurla, Ghatkopar, Vikhroli, Bhandup, Mulund, Thane, Diva, Dombivli and Kalyan Junction. All services plying beyond this junction run slow. Trains usually start from and terminate at important stations.

Electrification

CR converted the Central line from the previously used 1500 V DC electrification to 25,000 V AC on 5 May 2013 from Kalyan to Khopoli and Kalyan to Kasara. Electrification on the Lokmanya Tilak Terminus-Thane-Kalyan section was completed on 12 January 2014. The entire route between CSMT to Thane was converted from 1500 V DC electrification to 25,000 V AC on 8 June 2015; thus completing the entire Central line search.
The conversion was expected to reduce maintenance-related failures The AC electrification system needs lighter overhead wires than that of DC, which has thicker and heavier contact wires and pantographs that are prone to fast wear and tear. The railway is estimated to save around 120 crore annually from reduced transmission loss and regenerative braking, and conserve 33% energy as a result of the conversion.

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. 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.
