In 1958 Belgian State Railway NMBS ordered 55 samples of four-axle diesel electric loco from manufacturer Cockerill-Sambre. The locos had been numbered for 201.001-055 (later 5901-5955). The BLW 8-608A motor is an American design and develops 1750 hp. The locos reached a maximum speed of 120 km/h and were used in passenger and freight service till 1988.
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.
