The Chinese qinghai-tibet railway, which opened in 2006, has had the highest train tracks in the world for more than a century in the andes mountains of South America. The highest point of the qinghai-tibet railway lies at tanggula mountain pass, 5,072 meters above sea level. Previously, the lager line traction task is completed by the United States imported NJ2 locomotive.




At 11:00 am on June 11, the passenger train Z6801 arrived at Lhasa station, accompanied by the clear whistle of HXN30311 locomotive, marking that the china-made plateau locomotive officially took over the passenger train traction task on the line guela (lasa-golmu) of the qinghai-tibet railway.

HXN3 plateau locomotive, which is responsible for the grain-line traction task, is a high-power ac drive diesel locomotive developed by CRRC dalian company according to the special geographical environment in the plateau area of China. With a maximum speed of 120km/h and rated power of 3100kW, the locomotive is featured with large power, simple structure, high reliability and small maintenance workload. Locomotive diesel engine adopts plateau type supercharger, when altitude and ambient temperature change, the output power of diesel engine will be automatically corrected.



Car in dalian company to cooperate to golmud locomotives, try using type NJ2 locomotive with HXN3 control to achieve gamla line passenger traction locomotive reconnection, after-sales service group cooperate with locomotives in two kinds of locomotive after comparison and analysis, test, on June 10th for the first time in the form of controlled by NJ20030 + HXN30311 locomotive reconnection, locomotive traction passenger Z6801 times mission (is NJ2 and HXN3 hand in hand to do a task), the group of locomotive on June 11 to Lhasa, the locomotive running in good condition.


Up to now, HXN3 locomotives running back and forth on the gray-line are all towed in this way, officially undertaking the daily towing task of 12 pairs of passenger trains running back and forth on the gray-line.




This time, the big locomotive's "tough guy" HXN3




Not only greatly alleviated the locomotive power tension situation




It also provides locomotive power guarantee for the next phase of passenger and freight trains




We believe that the full localization of the qinghai-tibet railway is just around the corner




Are you looking forward to it?
