German Federal Railway class 82
Germany 1950 41 produced
The first new acquisition by the Bundesbahn was a powerful shunting locomotive that should also be able to be used in line service. It was intended to replace the class 87 with the vulnerable Luttermöller drive and ten-coupled Länderbahn tank locomotives. In the new class 82, only the third axle was fixed and two outer axles on each side were combined in Beugniot bogies. This meant that the locomotives could be approved for 70 km/h and were used not only on large marshalling yards but also on steep ramps.
