To carry out maintenance work of tracks, signalling and overhead equipment, a jumbo block of five hours will be taken on the UP and Down fast lines between Churchgate and Mumbai Central (local) stations from 10.35 am to 15.35 pm on Sunday, the Western Railway informed.

During the block period, all the local trains operating on the fast line will run on slow lines between Churchgate and Mumbai Central. 

Due to the block, some suburban trains will remain cancelled while some Churchgate-bound trains will be short-terminated/reversed at Bandra/Dadar stations.
