DB Class 151

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.

Production

On 21 November 1972 the first locomotive, 151001, was delivered by AEG and Krupp. It was followed by 11 further pilot locomotives, which were extensively tested before the main order was built. Altogether 170 locomotives were ordered, which were based at first in Hagen and Nuremberg.

Variations

Originally the Class 151 was also suitable for passenger service, however it is now not possible due to not having required safety equipment. Some engines were fitted with automatic coupling (type unicupler AK69e) to haul heavy ore-trains.
