5 faults in 9 days
Train services between Yew Tee and Kranji on the North-South Line were disrupted for four hours and 38 minutes.
This was due to a damaged power collecting device on the train that affected the third rail, which supplies power to the trains.
The Bukit Panjang LRT service was disrupted at midday because a power and signal collecting assembly on an LRT train got dislodged, hitting a signal rail and causing a power trip.
Train services between Yew Tee and Jurong East MRT stations were disrupted in both directions due to a "track intrusion". A man was seen walking on the viaduct between Choa Chu Kang and Bukit Gombak MRT stations.
Circle Line trains between HarbourFront and Haw Par Villa stations were stalled during the morning peak hour because of a signalling fault.
In the afternoon, trains slowed down from Queenstown to Boon Lay on the East-West Line due to track faults at Clementi and Lakeside stations.
