The Central Railway on Thursday announced a 27-hour 'block' from the night of November 19 for dismantling the British-era Carnac Bridge between CSMT and Masjid Bunder on its suburban line in Mumbai.

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.
