The power outage in Mumbai Metropolitan Region during peak hours led to the cancellation of 40 train services on Central Railway (CR) and 46 on Western Railway (WR).
As trains ground to a halt, and with no clarity on when power supply would resume, thousands of passengers scrambled off the trains and began trudging to their destinations.
Power supply disruption forced CR and WR each to reschedule five long-distance trains.
Mukesh Kamlashkar, who was among those walked on the tracks to reach Parel station, had boarded the train at Titwala. The biotech engineer was on way to KEM hospital.
