The Class 151 is an electric heavy freight locomotive built for German Federal Railways between 1972 and 1978.

They were built as a replacement for the ageing Class 150, in order to cope with the increased requirements of this type of locomotive, in particular the desire of a 120 km/h (75 mph) top speed.

[citation needed] Originally the Class 151 locomotives were also suitable for passenger service, however it is not possible anymore due to the lack of required safety equipment.

[citation needed] Deutsche Bahn's Class 151 fleet was sold to leasing company Railpool in 2017.

Two of them operate on freight services with torpedo cars, while one locomotive serves as a spare parts donor.
