Barring delay of a few minutes, trains were on schedule.

On the CR, the mega block was between 11.30am and 3.30pm. While the block on the main line was between Kalyan-Thane on the up-line on the fast-track, on the harbour line services between Vadala-Mahim and the up-line between Kurla-CST were suspended. Overcrowded trains on the main line were behind schedule. On the harbour line , services towards Bandra and Andheri were also suspended and CST-bound services were diverted to the main line. Passengers complained that slow line services were behind scheduled till 5pm.
