The class MY is a series of diesel-electric locomotives built in the years 1954–1965 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 bought inside Denmark for several decades.^[1]

History

In the early 50s the DSB was starting to look for a new type of locomotive that could replace the steam locomotive hauled services in Denmark.

The DSB ordered the first four units which arrived to Elsinore in 1954. The locomotives quickly became very popular among both passengers and crew. The units 1101-1105 and 1145-1159 had a 1700 horsepower engine, whilst the units 1106-1144 had a 1950 horsepower engine.

In their early years, the locomotives worked 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 (which many continues to do for private railways in both Denmark, Norway, Germany and Sweden.

In the 80s 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 - therefore, the DSB still have MY locos in service. The others have either been scrapped or, as mentioned above, sold to diverse private operators in Norway, Germany and Sweden.

A very similar locomotive, the Class MX was equally as popular - and many locomotives similar to the MY in other countries exist. Among these, the following can be mentioned:

• The NSB Class Di 3
• The MÁV Class M61
• The CFL Class 1600
• The NMBS/SNCB Class 52-54

Preservation

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 under the Danish Railway Club (DJK).^[7]
