Central Railway will operate a 10-hour special traffic and power block on Mumbai suburban sections between the Mulund–Thane and Diva–Dombivli lines from midnight to 10 am on Sunday, March 22, to facilitate platform extension works at Thane and Dombivli stations for accommodating 15-coach trains.
According to a press release issued by Central Railway on Saturday, the block will be carried out on the UP and DOWN Slow lines between Mulund–Thane and Diva–Dombivli, impacting Mumbai local as well as mail and express services.
The suburban services will remain cancelled intermittently during the block period. Several DOWN Slow services from Parel and Chhatrapati Shivaji Maharaj Terminus (CSMT) between late Saturday night and Sunday morning will be diverted on the Fast line at Mulund and later re-diverted to the Slow line at Thane.
These trains will also skip halts at Kopar and Thakurli stations after being diverted via Diva.
Similarly, UP Slow services departing Kalyan between late Saturday night and Sunday morning will be diverted on the Fast line and will not halt at Thakurli and Kopar stations. They will be re-diverted between Diva and Thane, and further between Thane and Mulund.
During the block period, fast trains in both directions will make additional halts at Kalva, Mumbra, and Diva stations.
All local train services between Mulund–Thane and Diva–Kalyan will remain suspended during the block window. Additionally, all services originating from or terminating at Dombivali will remain cancelled on Sunday.
Mail and express trains will also be affected. DOWN trains departing CSMT or Dadar will be diverted via the fifth line between Vidyavihar/Thane and Kalyan, while UP trains heading towards CSMT/Dadar will be diverted via the sixth line between Kalyan and Thane/Vidyavihar.
The railway administration said the block is essential for infrastructure upgrades and passenger safety, and has appealed to commuters to bear with the inconvenience.
