SINGAPORE - A Wednesday morning slowdown on MRT train service on the East-West line was caused by a door fault, said SMRT.

In response to queries, SMRT said technicians retrieved an earring and two beads that caused the door to jam at 8am on an east-bound train travelling from Joo Koon to Dover.

It added that trains travelled at slower speeds, and that passengers at Chinese Garden MRT station were asked to alight and told to board two additionally deployed trains instead.

Earlier, commuters had vented their frustration on social media, with a photo making the rounds purportedly showing a screen announcing an additional 10 minutes of travelling time between Joo Koon and Clementi stations on the East-West Line towards Pasir Ris. Others tweeted pictures of long queues at MRT stations. SMRT did not issue any reaction on its Facebook or Twitter pages.
