In the late 1960s, the Deutsche Bundesbahn recognized that the standard locomotives of series 140 and 150 were insufficient to meet the growing transportation demands. One was too weak (BR 140), and the other was too slow (BR 150). A new type of locomotive was needed. What the engineers then put on the tracks was, simply put, a six-axle version of the 140. However, the frame and bogies were inspired by the series 103. The new machine was classified as series 151. With 170 units, it became a defining feature of heavy freight trains. Initially, the locomotives sported a beautiful chrome oxide green livery before transitioning to a stylish ocean blue/beige. Eventually, after their phase in signal red, they appeared in bright traffic red with single-arm pantographs instead of the original scissors-type pantographs. In this outfit, they remained actively in service with DB Cargo until the summer of 2024. Model railroaders, on the other hand, can enjoy a significantly longer operational life for the 151. Prototype: Electric locomotive series 151 of Deutsche Bahn AG. Basic color scheme in traffic red. Operating number 151 035-3. Operational condition from 2008. Model: With digital decoder mfx+ and extensive sound functions. Regulated high-performance drive with a centrally mounted flywheel. Each bogie drives two axles via cardan shafts. Traction tires. Direction-dependent three-light front signal and two red tail lights, conventionally operated, digitally switchable. Front signal on locomotive sides 2 and 1 can be separately turned off digitally. Double A-light function. Cab lighting changes with the direction of travel, and engine room lighting is digitally switchable. Additionally, a starting lamp can be digitally controlled based on the direction of travel. Lighting features maintenance-free warm white and red LEDs. With energy storage capacitor. Detailed roof structures with newly designed single-arm pantographs.
