7 1/4 inch gauge battery electric 0-4-0 with driving truck

A scratch-built 0-4-0 battery electric locomotive, 24 volt Parkside controller with hand-held controller, powered by a pair of batteries in the braked driving truck. Steel chassis with wooden superstructure, it's been carefully thought out such that the outfit is easy to transport and couple together, with a quick-detach trailer type plug and socket connecting locomotive and driving truck.
