The Class 85 was a German goods train tank engine and standard locomotive (Einheitslok) with the Deutsche Reichsbahn.

History

In 1931, the DRG ordered ten locomotives from the firm of Henschel that were taken into the fleet as numbers 85 001–010. The Class 85 was intended for hauling passenger and goods trains. They were however also employed as pusher locomotives on the Höllentalbahn in the Black Forest. Thanks to this engine, the Höllental Railway could do away with rack railway operations from 1933. The running gear and the superheated system were taken from the Class 44. The boiler, with a few minor alterations, was the same as that of the Class 62. All the locomotives were stabled at the Freiburg shed. Apart from number 85 004, which was lost in the Second World War, all the engines were in operation in the Black Forest until 1961, the year the route was converted from experimental electrical operations with 20 kV/50 Hz lines to the usual Deutsche Bundesbahn standard of 15 kV/16 2/3 Hz. One engine, number 85 007, was still in service in Wuppertal until the end of the year, but they were all retired by the beginning of the next year.

Preserved Locomotives

Number 85 007 belongs to the town of Freiburg im Breisgau. It is not operational, but is maintained by the Bahn-Sozialwerk-Gruppe. The engine is housed in the former locomotive shed.
