 At about 7.45am, on 19 November 1946, the front two carriages of the 7.08 Liverpool to Wynyard service jumped the points and diverted onto the Sydney Abattoirs branch line, near Rookwood station.Both carriages derailed, and the second car began to topple, but hit a steel stanchion, which was bent into the "shape of a boomerang" by the impact.Somehow the stanchion held and prevented the carriage from falling over completely.
