Like many others, Baureihe (Class) 150 is a fruit of Deutsche Bundesbahn's early-1950s program calling for development of several new electric locomotive types. What makes this freight-service locomotive stand out among the likes of the 110, 140 etc. is that it's got six axles to make for higher friction weight to deal with steep grades or very long and heavy trains. Just look at the incredible maximum traction it can deliver -- 420 kN!.

150s were built from 1957 through 1973 by AEG, Krauss-Maffei, Krupp, and Siemens. Not many are still in service; they mostly worked as pushers on steep ramps in the end and may well have been phased out completely by now.

  • Traction: 420 kN maximum, 198 kN sustained
  • Top speed: 100 km/h
  • Total weight: 125 or 128 tonnes depending on date built (20.83 resp. 21.33 tonnes per axle)
  • Length: 19.49 m
  • Width: 3.13 m
  • Height: 4.62 m
  • Distance between axles in bogie: 2.25 m
  • Distance between bogies: 9.7 m
