In an update on Facebook at 9.55pm, SMRT said that had to end passenger service at 10pm for urgent repair works.
“Our engineers have assessed the situation. We need to end passenger service earlier at 10pm between Choa Chu Kang and Bukit Panjang stations for urgent repair works.
“Train service on the loop side between Bukit Panjang and Senja stations remain available via Service B,” it said.
Free regular bus services between Choa Chu Kang and Bukit Panjang will also be available throughout the rest of Tuesday evening, added SMRT.
In an update on Facebook at about 11.45pm, SMRT said staff had begun operations to haul the faulty train back to the depot after all commuters safely got off at Teck Whye station.
“While en route, a tyre on the faulty train deflated, causing the train to sag on one end. This led to a bar underneath the carriage to make contact with the power rail,” it added.
“To prevent further damage to both the train and the power rail, we will jack up the train, replace the deflated tyre, and restore the train to its correct height before hauling it back to the depot tonight.”
It added that engineers and technicians will work through the night to restore services as soon as possible.
