SINGAPORE - An artificial intelligence-based system that is able to identify issues that disrupt rail operations, like train doors not closing properly, will be introduced on the North-South and East-West MRT lines by the end of 2024.
In the first quarter of 2023, the CCL clocked 1.47 million train-km before a delay of more than five minutes, compared with 1.84 million train-km for the whole of 2022. This was calculated using a 12-month moving average of mean kilometre between failure Developed by SMRT’s subsidiary Strides Engineering, Overwatch applies AI to interpret the data feed from an existing overview display system, which shows the real-time data visualisation of the operations on the CCL.
She noted that the AI system will alert SMRT staff if it detects any anomalies, so they can take pre-emptive action to address the faults. A ticking timer appears above a train in the system’s visualisation of the network when it has stopped for an abnormally long period. The colour of the timer changes as the delays are prolonged, to signal urgency. In a disruption where multiple trains are stalled, this visual cue helps the controller prioritise the recovery effort among the affected trains.
When Overwatch is implemented across the other MRT lines operated by SMRT, the system will give SMRT staff a real-time overview of the condition of all trains in operation across multiple lines.
