On Wednesday 21 March 2007, passenger express Train 200 collided with the rear of stationary passenger express Train 201 during a planned setback manoeuvre at National Park when radio communication failed.
One passenger travelling in the rear passenger carriage on Train 200 received a minor injury. The buffer at the rear of the train was damaged.
A safety issue identified was the reliance, during the setback movement, on a single line of communication between the locomotive engineer and the train manager piloting the train from the rear carriage. Safety actions have been taken to address the safety issue.
