German Federal Railways (DB) class 152 (ex-Bavarian EP 5). 4-B-B-4 wheel arrangement. 4 powered drivers. Drivers coupled to allow for better cornering ability. Sprung trucks at each end. Simulated driving rod action. Coupling hooks at each end. Electronic direction control switch. Length over buffers 19.8 cm (7-7/8").
At the beginning of the 1920s, the extensive electrification program in southern Germany was almost finished and the German State Railway, Bavarian division, needed a strong multi-purpose locomotive designed for main line service.
The locomotive had four motors, whose power output was connected to the driving wheels via engine rods. The four motors were actually tandem double motors, with separate sets of drivers. To improve its running ability and to reduce the weight on the drivers, pony and trailing trucks were added.
Until 1924 and 1925, the engines were still in their Bavarian dress with the old numbers EP 5 21 501 - 535. They were then renumbered E 52 01 - 35. The German Federal Railways classified them as the 152.
The maximum speed limit was set at 90 km/h (56 mph). They had an hourly rating of 2,200 kW at a speed of 62.5 km/h (40 mph). It could offer a continued performance of 1,660 kW at 76.3 km/h (48 mph).
From the date of delivery until 1945, all these engines were stationed at either Munich or Garmisch. As the West German electrification program was extended, some engines were reassigned to other divisions such as Regensburg, Nürnberg, Stuttgart, Kaiserslautern, Frankfurt (M), Seelze and Osnabrück.
