Central Railway, while announcing its Mumbai local train updates, said it will operate a mega block on Sunday, August 23, on suburban sections of the Main and Harbour lines to carry out engineering and maintenance work, affecting several local train services.
On the Main Line, a block will be imposed on the CSMT - Vidyavihar UP and DOWN slow lines from 10.55 am to 3.55 pm.
During the block, DOWN slow services departing CSMT between 10.48 am and 3.45 pm will be diverted to the DOWN fast line between CSMT and Vidyavihar. These trains will halt at Byculla, Parel, Dadar, Matunga, Sion and Kurla before being diverted back to the slow line at Vidyavihar.
Similarly, UP slow services departing Ghatkopar between 10.19 am and 3.52 pm will run on the UP fast line between Vidyavihar and CSMT, with halts at Kurla, Sion, Matunga, Dadar, Parel and Byculla.
On the Harbour Line, the Kurla - Vashi UP and DOWN lines will remain under block from 11.10 am to 4.10 pm.
Harbour Line services between CSMT and Vashi, Belapur and Panvel will remain suspended during specified hours. Special services will operate between CSMT - Kurla - CSMT and Panvel - Vashi - Panvel.
Passengers will also be permitted to travel via Thane - Vashi/Nerul between 10 am and 6 pm during the block.
Meanwhile, Central Railway on Friday said that it will operate a special traffic and power block at Diva station on three consecutive nights to facilitate the construction of the Kalyan End Foot Over Bridge (FOB).
According to an official statement, the block will be carried out from 1.20 am to 3.20 am, for two hours, on the nights of August 21-22, August 22-23 and August 23-24, 2026.
The special block will be undertaken on the UP and DOWN slow lines between Kalva and Dombivli.
The work involves construction of the Kalyan End FOB at km 42/128-130 at Diva station. The traffic and power block has been planned to allow the required infrastructure work to be carried out safely.
During the block, two late-night suburban services will be diverted.
The train departing from CSMT at 12.08 am for Kasara and the train departing from CSMT at 12.12 am for Karjat will be diverted on the Down fast lines between Thane and Kalyan stations.
As a result, these services will not halt at Thakurli and Kopar stations during the affected period.
