Central Railway’s plan to increase the number of 15-car suburban train services has encountered delays due to limited space at Chhatrapati Shivaji Maharaj Terminus (CSMT). Although 54 such services were introduced on August 15, only Platform 7 currently accommodates the longer trains.
To support additional 15-car services, platforms 5 and 6 need to be lengthened by approximately 45–50 metres. However, the expansion requires significant engineering work, including track realignment and modifications to signalling systems, potentially affecting train movements near the terminus.
“The biggest concern is that the extension could force trains approaching CSMT to slow down, with speed restrictions potentially increasing from the existing 40 kmph to 20-25 kmph due to changes in track alignment and the positioning of points and signals,” said a CR official.
The official explained that the project would involve relocating railway tracks and points at 10–12 locations, adjusting signal positions and straightening sections of track by up to seven degrees.
“There are 10-12 track points at CSMT that would need to be shifted. This will enable us to extend the length of platforms by 45-50 meters. However, the impact will be seen towards Masjid as the tracks will have to be shifted further north leaving little space for trains between the two stations,” the official explained.
The official further warned that lower speed limits could disrupt operations on the already congested approach to CSMT. Careful scheduling would also be necessary to minimise interference with fast local services entering the station.
Railway sources indicated that the extension work is expected to begin after Diwali. Preliminary activity is already underway at the ends of platforms 5 and 6, where concrete slabs have been stacked.
The proposed upgrades are essential for expanding the Main Line’s 15-car services. Once completed, Central Railway could potentially increase their number from 54 to around 150, improving passenger capacity on routes connecting CSMT with Kasara, Karjat and Khopoli.
However, the project’s progress will depend on resolving engineering challenges while maintaining safe and efficient suburban train operations.
