DSB Class MY

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.

History

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

MY 1101 was built by NOHAB alone, but all subsequent units had bodies, underbodies and bogies built at Danish manufacturer Frichs in order to limit foreign currency spending. For the same reason, and because of pressure from Danish industry, the electrical systems of MY 1105 and later were sub-supplied by Danish companies Thrige and Titan.

The DSB ordered the first four units which arrived at Helsingør in 1954. The locomotives quickly became very popular among both passengers and crew.

To replace steam on branch lines, a similar but lighter locomotive, the class MX, was developed, incorporating a 12-cylinder 567 engine.

DSB Class MY 1201-1202

DSB MY 1201 og 1202 was two diesel locomotives built by Frichs in Aarhus, Denmark in 1957 and 1960.

The locomotives were built by Frichs with a disel engine produced by Burmeister & Wain, while Thrige-Titan delived the electric equipment. In 1957 the first locomotive, MY 1201, was delivered followed by the second, MY 1202, in 1960. Due to the curved forms of the locomotives the first locomotive was named Marilyn Monroe. The production of the second experienced severe delays and was named My Fair Lady after the opera which also premiered at the time after numerous delays. The locomotives were unstable and error prone and spent longer being serviced than in operation. They were in operation until 1969 after which they were retired in 1969 and scrapped in 1971.
