DR 137 283 bis 287

The railcars 137 283 to 287 were a series built for the Deutsche Reichsbahn as fast railcars for the Ruhr express service. They were made alongside the five two-part Ruhr railcars as a comparison variant, so that cars with hydraulic power transmission could be tried in that service. Westwaggon built them and they were delivered in the second half of 1939, but the Ruhr traffic they were meant for was no longer possible, so they were given to the Dresden directorate and hardly used. Each was a three-part unit with two end cars and a middle car on unpowered Jacobs bogies, driven by a diesel-hydraulic plant with Voith two-converter transmission. The first three had the Maybach GO 56 engine, and the last two had the Mercedes-Benz OM 86. Two cars stayed with the Reichsbahn after 1945 and two went to the ČSD; the last three-part Ruhr railcar was retired in 1970.
