Usually, when the MRT train doors are about to close, there is a ringing sound and an announcement to warn commuters.

However, last Friday evening, as I was boarding the train at Jurong East on the North-South Line, the doors closed without any warning.

I was about to step onto the train but managed to withdraw my leg in time.

There was an SMRT attendant present and I asked her why she gave the signal for the train to leave when it was not full and passengers were still boarding.

She replied that the closing of the doors was done by computer.

A fellow commuter told me that this is not the first time the doors closed without warning.

This is a very dangerous problem.

I hope SMRT will address it before a serious accident happens.
