"The earlier examples used mainly timber frames, whereas aluminium or durallium were used more often for the frames in the late '70s and '80s."
Motor trolleys were used by "inspectors of the Permanent Way" (track inspectors), track gangers and maintenance staff and, in some cases, station masters.
Although most commonly used for inspection purposes, they could also be used to transport small amounts of materials and tools to a remote worksite, including towing a material trolley if required.
"Due to the small size and light weight of motor trolleys, they were very useful to travel along, and get equipment into, remote areas where the track was damaged by minor slips or washouts and could not take the weight of a locomotive until repaired," Mr Pound said.
Jigger rides will be available between 10am and 4pm on Monday. Rides cost $2 (cash only) and refreshments will be available.
