History

After having great success with the MY locos, DSB started to search for a lighter locomotive for some of the smaller stretches on which the MYs were too heavy to run.

The first unit, 1001 arrived to Denmark in 1960 and got just as popular as its big-brothers in short time - the first 20 units (1001–1020) produced 1,425 horsepower (1,063 kW) whilst the last units, 1020-1045 produced 1,445 horsepower (1,078 kW).

Many of the MXs have been sold to Danish private railways, but some have also been sold to Sweden and some other countries. In Sweden they are called TMX, as diesel locomotive class designations usually begin with T there. Informally nicknamed Gammel Dansk referring to the popular herbal liquor associated with Denmark, whilst also being a popular name as it means "Old Danish" literally translated.
