The company of Allrad-Rangiertechnik in North Rhine-Westphalia was a manufacturer of road-rail vehicles which had the distinction that each wheel was powered by a separate hydraulic motor. In the nineties, they also started to offer the DH 440 “cargo-Lok” as a conventional shunting locomotive that also used the same propulsion technology. It had a Deutz diesel engine that provided 370 kW. As many parts as possible had been taken from truck building.
Three prototypes were delivered to Deutsche Bahn, to the Augsburger Localbahn and to the Swiss Varo Energy AG. Due to many problems which were found during testing, no additional locomotives were ordered. The project was cancelled in 1999 when the owner of the company died and Allrad-Rangiertechnik became part of Translok.
