After the Second World War, various European locomotive manufacturers began developing diesel-electric locomotives, which began to displace steam traction in the USA. In Sweden, Nydqvist and Holm AB (NoHAB) acquired the license to manufacture diesel locomotives for the Electro-Motive Division (EMD) in 1949. The Americans owned an export version of the F-series, which had a driver's cab at both ends. For the lighter superstructure in Europe, locos were equipped qith six instead of four axles. Customer could choose between six (Co'Co wheel alignment) or four (A1A) (A1A) driven axles. To replace steam locomotives on the main lines, the Danish state railway DSB purchased a total of 59 copies of the 101 t MY between 1954 and 1965. The EMD 16-cylinder engine 567B was set to an output of 1750 hp at 900 rpm in the first four locomotives. All other locomotives received the improved 1900 hp version 567C. The top speed was a uniform 133 km/h. All locomotives carried a steam boiler to heat passenger trains. From the 1970s, the boiler was removed from the machines that were only used in freight transport. A number of locomotives now run on private railways, including in Germany. Different starting processes can be selected with F1: 1x press button = warm start / press button 2x = false start / press button 3x = cold start
F5 enables the heavy load mode: The diesel notch is always one up compared with normal operation. If you want to jump two notches, simply set CV 104 to 170 (instead of 150).
F27 turns on the manual ntoching. Once F28 is on, you can use F28 to notch up and F29 to notch down. F27, F28, and F29 must be turned off to return to normal mode. If F27 is off and you press F28, the prime mover will run to full speed.
F17 will bring the locomotive to full stop.
