A door on a Singapore MRT train carriage remained open even though it had started moving off from the train station.

That was the situation presented in a video uploaded on Reddit Singapore by u/novajimster on Monday, March 11, 2019.

Here is the video.

From the videos, the train appears to have been on the North-South line, travelling from Ang Mo Kio to Yio Chu Kang.

The gaping door was secured by what appears to be a staff member who appeared in both videos.

This isn't the first time train doors have opened mid-journey.

In January 2016, the doors of an LRT train opened mid-journey while going from Bukit Panjang to Senja.

The cause for that particular incident was a signalling fault, which forced staff to override the system so they could drive it manually.

Statement

Responding to Mothership's queries, SMRT Vice President of Corporate Communications Margaret Teo said:

"On 11 Mar at around 7:30pm, a northbound train at Ang Mo Kio MRT station left the station with one of its doors still open. The station manager was inside the train and at the door handling a train door fault when the train moved off. He immediately kept all commuters away from the door. In-train announcements were made to tell commuters to keep clear of the door area and hold on to grip poles.

The train stopped shortly after travelling around 200m and returned to Ang Mo Kio station, where all commuters disembarked safely. The train was immediately withdrawn from service. Initial investigations showed that the station manager had made an error that allowed the train to move with a door still open. We have suspended the station manager with immediate effect. Safety is our top priority. We are sorry that this incident happened."
