As the first serious drizzles hit Mumbai, the train services on both Central and Western railways collapsed. Amongst the two, CR was in severe trouble especially during evening peak hours.

All local train services came to a standstill on various locations along the CR route. The problem began at around 8.15 pm when the overhead wire on the section between Sion and Matunga could not hold the power due to which the wire saw sparks and trains had to be shut down on the slow line. This happened when the drizzles fell on the wires carrying 25000-volt.
