while the first train was being detrained and the automatic platform doors were opened, a separate protection module was activated to block off the entire length of the platform at joo koon station. the module notified the second train's signalling computer that the joo koon station's westbound platform was occupied and to stay clear of the platform. the second train stopped at the correct distance behind the first train while the automatic platform doors were open. however, once the doors were closed, the platform length protection module was removed. when the signalling on the second train detected the first train as only three cars instead of six, it started moving to close the perceived gap between both trains for the distance of three cars, thus allowing the acceleration of the second train and the rear-end collision with the first train. smrt later explained that when the first train was detraining at the platform, a signal was given off to show that the platform was occupied. however, when the platform screen doors closed, the protection was then removed, allowing the second train to hit the first.
