The class MY is a class 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 sourced from within Denmark for several decades.^[4]
