In the early morning of 19 January it suddenly started backing out of the depot on its own. It went up a quarter mile away, crashed into state bus which caught fire went it smashed into an electric feeder box and a water tap. Tramways sources explained that power supply to the overhead wires at the siding had been switched off for some repair work. There was presumably, some defect in the reversal handle of the tram and its main switch had not been put off.
