Warwick safety device
A safety appliance placed near the upper end of an inclined haulage road to stop a tram running wild down the incline. It consists of a heavy beam longer than the height of the roadway and is normally held up entirely at roof level, but is hinged at the lower end. In the event of a tram running away from above, a haulage hand can pull a rope that releases the upper end of the beam that drops and stops the tram.
