On the morning of 3 May 2017, Downtown line (DTL) train services towards Chinatown were disrupted for 7 hours due to a platform screen door (PSD) malfunction at Botanic Gardens MRT. This, as stated by SBS Transit, the line's operator, was due to a signalling-related fault. This resulted in the doors being unable to open automatically, which meant that staff had to manually operate them whenever a train arrived at the station, which took some time and thus caused delays in train services.
