Shivaji Sutar, chief public relations officer of Central Railway (CR), said, “A special 27-hour special traffic and power block will be undertaken on November 19 and 20 [Saturday and Sunday] for the dismantling work.”

“All suburban services on the main central line will be short-terminated/short-originated at Byculla, Parel, Dadar and Kurla stations. The frequency of local train services between Byculla, Parel, Dadar, Kurla, and Thane and beyond will be less. On the harbour line, the suburban services will be short-terminated/short-originated at Wadala. Local trains will be run at less frequency between Wadala and Kurla and beyond,” Sutar added.

The mega block will start at 11 pm on November 19 and end at 2 am on November 21, due to which the schedule of suburban and express trains will get affected during this period, a release by the CR said.

No local trains will ply between the Chhatrapati Shivaji Maharaj Terminus (CSMT) and Wadala station on the Harbour line, and no local as well as long-distance trains will run between CSMT and Byculla on its main line during the special block, Central Railway's chief PRO Shivaji Sutar told PTI.

All six railway lines between CSMT-Masjid Bunder will remain closed for train traffic during the block which will start at 11 pm on November 19 and end at 2 am on November 21.
