What have Tilak Nagar, Govandi and Mankhurd been 'harbour'ing? The usual, no secret - piling (number of) passengers. These three stations on Central Railway's Harbour line are the up-and-comers, but only in terms of commuter population, not the required infrastructure. And the limited infrastructure is supposedly due to the fact that Harbour line has only two tracks, and no fast trains.

Also, increase in trains' length - from nine-car ones to 12-car locals - has added to passenger footfall on the network. Go for a stroll at these stations and you'll see the problems in all their glory - unpaved platforms, missing roofs and narrow entry-exit points, to name a few.
