Northbound train service between Newton and Toa Payoh in Singapore was disrupted at around 9.05am today due to a cable which caught fire in the tunnel at the Newton station.

In a statement, train operator SMRT said free bus services were activated immediately between Newton and Toa Payoh.

In addition, bus bridging services were provided for commuters between the Marina Bay and Toa Payoh stations.

At 10am, the northbound service between Marina Bay and Toa Payoh was disrupted as traction power was switched off for the removal of the damaged cable.

It said all northbound trains were turned around at Newton station to head southbound.

Affected passengers can make a transfer at Bishan and Dhoby Ghaut stations to travel along the Circle Line where normal train service is available.

According to the statement, the fire has been put out and SMRT was working closely with the police and Singapore Civil Defence Force to resume train services, estimated in about an hour.
