The class MY is a class of diesel-electric locomotives built in the years 1954–65 by NOHAB. A total of 59 units, numbered 1101–1159, were delivered to the Danish State Railways. Powered by GM-EMD engines, the locomotives represented a significant change in rolling stock policy — motive power had largely been sourced from within Denmark for several decades.[1]

History[edit]

In the early 50s the DSB was starting to look for a new type of motive power that could replace steam locomotives in Denmark.

The DSB ordered the first four units which arrived at Helsingør in 1954. The locomotives quickly became very popular among both passengers and crew. Units 1101–1105 and 1145–1159, known as class MV, had a 1,700 horsepower (1,300 kilowatts), whilst units 1106–1144 had a 1,950 horsepower (1,450 kilowatts).

In their early years the locomotives hauled express trains (later known as InterCity) and heavy freight services, but in their later years they were transferred to smaller regional and light freight services.

In the 1980s and 90s the DSB began to have less and less need for them, and the last ordinary MY-hauled train ran in 2001. One unit however, 1135, is now a special service locomotive which runs special trains, so DSB still has MY locos in service. The others have either been scrapped or sold to diverse private operators in Norway, Germany and Sweden, who now use them on light freight duties.

A very similar locomotive, the Class MX was equally popular, and many locomotives similar to the MY survive in other countries. They include:

Preservation[edit]

DSB 1112 in the Danish Railway Museum.

A handful of the MY locomotives have been preserved, several in working order. MY 1101, in original maroon livery,[2] and 1159, in red/black,[3] are both preserved in running order by DSB Museumstog. MY 1112, having one side cut open, and one cab of 1129,[4] are on exhibition in the Danish Railway Museum. MY 1104 was preserved for a number of years by GM-Gruppen in Norway, but is now in the railway museum in Struer.[5][6] 1126, in special decorative livery, is under the care of Jysk Veterantog for the Danish Railway Club (DJK).[7] MY 1138 was transferred to Germany in 1999 and is still in working order, mostly used as a backup locomotive for freight trains.
