"The original vehicles were used by British railways in the nineteen fifties to transport goods to and from railway goods depots. The number of these vehicles used by British Railways must have been quite small compared to the Scammell mechanical horse of various types that swarmed around almost every goods depot throughout the UK at that time . Almost certainly this battery/electric would have been used only in city centres. It is thought that none of the Hindle Smart Jen-Helecs BR vehicles survived in service beyond the nineteen fifties.
The original vehicle was not battery/electric but powered with an Austin petrol engine and was built by Jensen Motors, who later on became well know as builders of luxury sports cars. They called the small articulated vehicle the Jen-Tug and it first appeared in the post war years. In 1949 Jensen made an agreement with Hindle Smart of Manchester to produce and market a battery / electric version of the vehicle, this vehicle was know as the Jen-Helecs. The boxes made of wood on each side of the chassis , contained the lead/zinc batteries. The vehicles were generally all known as Jen-Tugs. Meccano usually named their Dinky Toys after the manufacturer so called their model a Hindle Smart rather than a Jen-Helec ."
This little truck was in the Dinky catalogue from 1952 to 1959. It was originally released as 30w and switched to 421 and individually boxed from 1954 onwards. It is only found in the maroon livery of British Rail with a BR logo on the front of the cab above the windscreen. Hubs can be maroon or red, however I've only seen references to maroon hubs on the earlier 30w models.
