SINGAPORE - Train services on the East-West Line (EWL) were delayed just as the evening peak hour set in on Friday (May 18).

SMRT alerted commuters to the delay, which it attributed to a train fault, at 5.10pm.

The transport operator advised commuters to add 20 minutes to their travel time from Boon Lay to Queenstown, towards Pasir Ris.

According to an alert in the Land Transport Authority's MyTransport mobile application, the train fault occurred at Clementi Station and resulted in trains moving at a slower speed.

Service resumed shortly after, with SMRT saying it was cleared at 5.37pm.

"Trains are progressively returning back to normal speed," it said. "We apologise for any inconvenience caused."

The delay came a day after travel was disrupted due to a platform screen door fault on the North-South Line during Thursday's evening peak.

The disruption was first flagged at 6.06pm, and resumed at 8.23pm, more than two hours later.
