Over and above the fact that South Mumbai is experiencing unusual waterlogging this year, the Churchgate station got flooded on Thursday with water entering the tracks and even the heritage building. While underground Metro work has been going on for a while now, railway officials and transport experts feel that the Coastal Road work might be leading to the current situation.

Requesting anonymity, a senior permanent way maintainer said, "The tracks were waterlogged till the buffer ends. This has not happened in recent memory despite heavy rainfall." "It took some time for the water to recede, but this indicates that the water egress system has been disturbed," he added.
