NKS Trolley Motor Transporting Box A wooden box used for transporting the engines of the Gangers trolleys between the line in use and the Workshops at Spotswood. Engines were often changed over due to mechanical failure or being required for a service. Rather than send the complete trolley in for work, the engine was removed and transported. These boxes may have arrived at a location with an engine in it, to replace the one returning to the Workshops, cutting down the time that the trolley may have been out of use.
