SINGAPORE - Train service on the East-West line experienced delays during the evening rush hour on Tuesday due to track faults at two stations. It resumed at 7.06pm.

In a tweet at 5.44pm, SMRT said there would be an estimated 20 minutes of additional travelling time from Tanjong Pagar to Jurong East towards Joo Koon.

In a statement to the media, the train operator said track faults at Clementi and Lakeside stations caused trains to travel at slower speed from Queenstown to Boon Lay. A free bus service between both stations was activated.

"Commuters are advised to add 20 mins traveling time for train service between Bugis and Jurong East stations in both directions," SMRT said in the Facebook post.

The incident came hours after train service between Labrador Park and Harbour Front on the Circle line was disrupted for about 15 minutes on Tuesday morning due to a signal fault.

"We apologise for the inconvenience caused and we are committed to improving the North-South, East-West Line's rail service reliability through the on-going track renewal and re-signalling programmes," said SMRT's managing director of trains Lee Ling Wee.
