"Runaway" engines can be a problem next to a turntable pit. This even happened at an operating session on Steve Shores' HO scale model railroad on May 23, 2026. Fortunately, nobody was hurt and there was no damage to equipment. Amazingly, the headlight and engine sounds stayed on, even after the derailment!
