Service has resumed on the newly-opened Downtown Line 1 after it was disrupted for more than an hour on Friday due to a power fault.

Operator SBS Transit said service on the line was down at about 9pm due to a power fault, and apologised for the breakdown. SBS Transit said 50 passengers on one train were detrained at Bayfront station and that full service resumed at 10.10pm.

The operator deployed free bus bridging services for affected commuters, and buses passing by affected stations were also free.

It is the second breakdown for the six-station, 4.3km line which began operating just five days ago. The line runs from Chinatown to Bugis. On its opening day on Dec 22, service was disrupted for 15 minutes due to a train fault. The problem took place around noon at Bayfront station and delayed services between Bugis and Chinatown. It was quickly resolved and full service resumed not long after.
