Complete details, drawings and renderings

The elevated local train railway station at Kurla in Mumbai on Central Railway will have three lines, one for CSMT-bound trains, other for Mankhurd-Navi Mumbai bound trains and a central double discharge platform with a dead-end for trains terminating at Kurla. The layout will be similar to that of Parel, the only difference being that all this will be elevated.

The project involves construction of a 1,120m 59-span bridge linked to a central skywalk, linking all other foot bridges. As of today 35pc work is complete.

Rendering of new elevated Kurla harbour line station

The whole idea of taking the harbour lines and the station at an elevated level is two fold. The existing harbour line will then serve as 5th and 6th lines between Kurla and CST for outstation trains to segregate the existing main line traffic. Besides, it will not just add to capacity of the line, but also segregate the Mumbai Port Trust freight line and the Trombay goods line that bypasses the harbour line at Kurla.

Trains between Kurla and Mankhurd used to run till the late 1990s, but the Central Railway had stopped them after development of Navi Mumbai as there was increased traffic and these Kurla trains begun to prove as a hindrance to harbour trains starting from CSMT. After almost two decades now, once this station is ready in the next few years, the Central Railway will reviving the Kurla originating trains to Navi Mumbai.
