A power failure around lunch time on Monday knocked out part of the North East Line train services, causing 4 stations, HarbourFront, Outram Park, Chinatown and Clarke Quay, to be closed to the public. 100 passengers had to be evacuated from a stalled train just after Outram Park Station. The problem started at 12.45pm when a southbound NEL train stalled in the tunnel some 200 metres after leaving the Outram Park Station. Outside the affected stations, things quickly got busier as the breakdown stretched into the evening rush hour.
Investigations showed a wire which supplies traction power to the trains had come loose. Monday's transit breakdown is one of the longest in Singapore's history. The last such breakdown was in 1993 when there was an SMRT train accident and service was only resumed the following day.
