Despite major repair works and long preparation for the monsoon during the lockdown period, Mumbai's lifeline had to be suspended at various locations on both Central Railway (CR) and Western Railway (WR) due to waterlogging and other flooding-related issues. For the major part of the day, trains were stopped on both harbour and main lines of CR, while services on WR remained suspended between Churchgate and Andheri till late afternoon.

With the city locked down due to the COVID-19 outbreak and only a few trains running, both CR and WR had conducted uninterrupted preparations for the monsoon. But with the massive rainfall overnight, most parts of the city were flooded, disrupting railway services.
