description DB Class 120 Overview
The DB Class 120 is a German electric locomotive introduced by Deutsche Bundesbahn in 1979, notable as the world's first production locomotive to use three-phase AC drive technology with regenerative braking. It was designed as a universal mixed-traffic locomotive capable of pulling heavy InterCity passenger trains at speeds up to 200 km/h. This advanced power electronics technology pioneered by the Class 120 became the foundation for modern high-speed trains like the ICE 1.
help DB Class 120 FAQ
Why is the DB Class 120 important in electric-locomotive history?
It was the first production locomotive class to combine high-power three-phase asynchronous traction motors with electronic control for universal service. The technology influenced later German trains, including the ICE generation.
Could the DB Class 120 haul both passenger and freight trains?
Yes, Deutsche Bundesbahn conceived it as a universal locomotive capable of fast intercity work and heavy freight service. Its electronic three-phase drive provided the flexible speed and tractive characteristics needed for both roles.
What was the difference between Class 120.0 and Class 120.1?
The 120.0 designation covered the five prototype locomotives introduced from 1979. The 120.1 series comprised the production machines delivered during the late 1980s.
What replaced the DB Class 120 in regular service?
More specialized locomotives and multiple units gradually took over its work, including DB Class 101 locomotives on Intercity trains and ICE trainsets on high-speed services. Deutsche Bahn withdrew the last Class 120 locomotives from regular service in the early 2020s.
