Mumbai commuters, brace for major travel disruption this Sunday. Central Railway’s Mumbai Division has announced a mega block on June 15, affecting several suburban train services to facilitate urgent maintenance and engineering work.
According to a statement from Central Railway’s Public Relations Department, services on the CSMT Mumbai–Vidyavihar Up and Down slow lines will be impacted between 10:55 am and 3:55 pm. During this time, Down slow trains from CSMT will be diverted to the Down fast line up to Vidyavihar, halting only at Byculla, Parel, Dadar, Matunga, Sion, and Kurla. Similarly, Up slow services from Ghatkopar will run on the Up fast line to CSMT, stopping at the same stations in reverse.
In addition, a block on the Panvel–Vashi Up and Down Harbour lines will be enforced from 11:05 am to 4:05 pm. Harbour line services between Panvel and CSMT (Up and Down) and Trans-Harbour services between Panvel and Thane during this window will be cancelled. However, special services will run between CSMT and Vashi, and trains will continue to operate between Thane and Nerul/Vashi. Port line operations will remain unaffected.
Railway authorities have appealed for public cooperation, citing that these blocks are vital for safe and efficient train operations. Passengers are urged to check train schedules in advance and plan alternative travel arrangements accordingly.
