The Class 150 is an electric heavy freight locomotive built for German Federal Railways between 1957 and 1973. They were built as heavy freight movers to be used on the increasingly electrified main lines of the DB, where they were set to replace the steam traction.

E50 091, rebuilt to the state as it was originally delivered from the factory (museum's locomotive)

In 1957 the first locomotive, 150 001, was delivered by AEG and Krupp. Altogether 194 locomotives were ordered and delivered.

Originally the Class 150 was also suitable for passenger service, however it did not have any steam or electric heating capability for the passenger coaches.

To date, the Class 150's starting tractive effort of 450 kN (100,000 lb_f) remains unparalleled on German rails - in fact it was very close to the breaking force of the chain couplings used at the time of its production. Some engines were therefore fitted with automatic coupling (type unicupler AK69e) to haul heavy ore-trains.
