In a viral video, the doors of a train departing from Ang Mo Kio station were fully open. The train moved 200m away from the station before it stopped and moved back to Ang Mo Kio station.
SMRT said that a station manager had made an error which allowed the train to move off from the station without the doors closing. The station manager was in the train and kept commuters away from the door. In-train announcements were also made to tell commuters to keep away from the doors and grab onto the hand poles.
Fortunately, none of the commuters were hurt. But they did get away from the incident feeling shocked.
