The Pasir Ris rail accident was a train accident that occurred on 22 March 2016, at the track switch on the East West MRT Line. A C151 train ran into two SMRT Trains trainee track workers at around 60 km/h, which resulted in their deaths. The two deceased workers were working on a track signalling issue at that time as part of a team of 15 track personnel. This incident was "the worst train accident" in Singapore MRT's history.
