Metro Railway services were disrupted Wednesday due to a breakdown in power supply to a Kavi Subhash-bound rake, shortly after its departure from Dum Dum station.
Passengers of the train, which halted on the tracks at 1 pm, were immediately evacuated and escorted back to the platform at Dum Dum station by the Railway Protection Force (RPF), Kolkata Police and state disaster management personnel, Metro spokesperson Indrani Banerjee said.
Truncated services were being run between Belgachia station in the north and Kavi Subhash in the southern part of the city owing to the snag.
Banerjee said work was on to rectify the problem and restore normal operation.
