DF11G Quasi-high Speed Passenger Diesel Locomotive


DF11G double-heading quasi-high speed passenger diesel locomotive is specially developed for grand speedup of railway. It is equipped with 16V280ZJA diesel engine, JF204D synchronous main alternator, ZD106E traction motor, and imported MTU or Cummins auxiliary diesel engine for auxiliary power supply. The running mechanism is quasi-high speed suspension bogie with wheel set and hollow axle. Speed monitoring system is set up for running safety and dynamic brake device is incorporated with full-power self-load function.

   Performance and characteristics: New technology of Lonworks network control is utilized. It has complete functions such as locomotive logic control, network multiple-unit control, fault diagnosis, remote supervision and diagnosis. The locomotive is excellent in both design and manufacture with streamlined body and standard pipeline, as well as power supply functions for passenger cars.
