阐述我国70吨级新型铁路货车的技术参数及优势,对未来全路货车更新换代情况进行预测。以兰新线嘉峪关—乌鲁木齐段为例,分析验证了在车站到发线有效长为850 m的条件下,采用70吨级新型货车按预测货流构成比例混编的列车开行5 000 t货物列车的可行性,提出采用70吨级新型货车可以提高货物列车牵引质量、提高运输效率、降低运输成本。
The technical parameters and advantages of the new 70-ton railway freight wagon in China are expounded, and the forecast of the whole truck wagon replacement will be predicted. Taking Jiayuguan-Urumqi section of Lanxin Line as an example, it is verified that the 5 000 t freight trains are operated on the basis of the predicted mix proportion of the new 70-ton freight wagons under the condition that the effective length of the departure line of the station is 850 m The feasibility of using a new 70-ton truck can improve the quality of cargo train traction, improve transport efficiency and reduce transportation costs.
