SINGAPORE – The authorities and rail operator SMRT are evaluating a new backup MRT signalling system that will allow trains to continue running if the onboard signalling equipment fails, after the completion of tests in July.
This new system – known as the smart automatic train control system – can provide an “additional layer of resilience” for train operations, said SMRT on Aug 25, in response to queries.
“In the rare event of the train-borne signalling system coming to a complete failure, train movement may not be possible, potentially leading to significant service disruption,” it added.
SMRT said the trial is linked to recommendations made by a task force in February to explore more back-up or bypass solutions that can help sustain or restore rail operations during disruptions.
Besides more backup solutions, other areas of improvement flagged by the task force include prioritising the renewal of trains, and signalling and power systems, as well as more comprehensive and standardised condition monitoring across the rail network.
The backup system that underwent tests is not intended to replace the existing communications-based train control signalling system – which is the main train control system supporting the safe and efficient operation of trains.
