On this day …….. 21st of July 1952
On the morning of July 20, 1952, the wheels of a Mosman tram locked. Despite the best efforts of the driver, the tram skidded more than a kilometre and a half downhill – at an estimated speed of over 70km/h – until it crashed through the blocks at the end of the rails, tore up almost 10 metres of road, and shot off the embankment, hurtling 18 metres through the air, onto rocks, and then into the harbour. The driver and conductor both suffered head injuries when they abandoned the tram during its descent. The two passengers left on board were also injured.
