September 22nd turned out to be the final day for 25171. Whilst hauling a ten wagon ballast train southbound at Arbroath the train ran out of control and was diverted into the goods yard since both main lines were occupied. It demolished the buffer stops and impacted the retaining wall causing major structural damage to the locomotive, not helped by two of the now derailed ballast wagons demolishing the rear of 25171. The guard and driverís assistant jumped to safety, the driver taking refuge in the engine room.

The No.2 end was leading, with the cab being crushed, the leading bogie was derailed. The No.1 cab was pushed upwards and crushed after being hit by the leading bogie ballast wagon, the second ballast wagon had slid under the leading wagon and been crushed. It is reported the engine was still idling after the collision had occurred.
