Central Railway’s Mumbai Division will operate a mega block on its suburban network on Sunday, September 21, 2025, to carry out essential engineering and maintenance works.
On the Main Line, Up and Down fast services between Thane and Kalyan will be affected from 10:40 hrs to 15:40 hrs. Fast and semi-fast locals departing from CSMT and Kalyan during this period will be diverted to the slow line between Thane and Kalyan. These trains will make additional halts at Kalva, Mumbra, and Diva and are expected to reach their destinations approximately 10 minutes late. Additionally, certain mail and express trains will be diverted via the 5th and 6th lines.
On the Harbour Line, services between Panvel and Vashi (excluding the Port line) will remain suspended from 11:05 hrs to 16:05 hrs. This suspension affects Harbour Line services between CSMT and Panvel/Belapur, as well as Trans-Harbour services between Thane and Panvel.
During the block, special local trains will run between CSMT and Vashi. Trans-Harbour services will continue to operate between Thane and Vashi/Nerul. Port line services will run as usual without any interruption.
Railway officials emphasized that these mega blocks are necessary for infrastructure upkeep and passenger safety. They have requested passengers to cooperate with the administration during this period.
