Bukit Panjang LRT: SMRT to 'bypass' burnt circuit breaker

SINGAPORE - Rail operator SMRT Corp has decided to bypass a circuit breaker that burst into flames yesterday evening.

According to Transport Minister Lui Tuck Yew's Facebook post on Tuesday, the tie-breaker - a type of electrical circuit breaker - that burst into flames was a new one that was installed just on Sunday to address "arcing" problems in the previous one.

But the new breaker caught fire on Monday evening, disrupting service for thousands of commuters.

Mr Lui said on Facebook that SMRT has completed a "bypass" of the affected tie-breaker in the LRT's inner loop.

The Straits Times understands this would allow the inner loop to power up without a circuit breaker. The Bukit Panjang LRT system has resumed service on its outer loop, some 18 hours after a fire disrupted operation.

Full service is expected by the evening peak period.

Investigations are still under way on how and why the fire occurred.
