The former Director of the closed in 1992 600mm narrow gauge line of Jarocin/ Witaszyce, Eng. Marek Kaniewski, is the head of our draisine manufacture department. Interlok had already sold six original hand pump cars from the 600mm branch of Bialosliwie/Naklo through Mr. Kaniewski. The large demand of international rail enthusiasts led to the fabrication programme, at the beginning in cooperation with the former partner ZNTK and the narrow gauge branch workshop of Bialosliwie.

Our current versions are modernized by implementation of free-of-maintenance roller bearings on the wheels and pump mechanism. Clients may chose how to arrange seats or benches, as well as whether to equip the cars with cogwheel or chain transmission. Wheels are cast in own moulds. The hand pump cars have two independent braking systems, a brake on the pump mechanism and a pedal/ lever brake on the brake shoes. On demand, the vehicles may be equipped with speedometer, lighting or a diesel engine. Height of platform is 650 mm, of pump mechanism 1500 mm over rail. Width of platform is 1300 mm and length including steps - depending on the gauge of the vehicle - between 2200 and 2400 mm. Weight is up to 250 kg. If not agreed otherwise by the client, maximum speed is reduced to 25/30 km/h for security reasons.
