In 1989, MaK (vehicle part) and ABB (electrical part) developed the DE 1024 diesel-electric series with three-phase power transmission for demonstration purposes. The MaK 12M282 diesel engine developed 2650 kW at 1000 rpm and generated the power for the six traction motors. Since the locomotive with its maximum speed of 160 km/h was also to be used in heavy passenger train service, it was fitted with a train heating system. The Deutsche Bundesbahn DB rented the three prototypes on a long-term basis, but because of the large numbers of DR diesel locomotives in the 130-142 series that were available after reunification, no series orders were placed. MaK finally sold the three prototypes to the Colonian HGK. In 2021 the last DE 1024 was scrapped. 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.
