提高货物列车平均重量是改善铁路运营工作的主要任务之一。这在如今实行经济核算和自负盈亏,铁路技术作业过程日益繁重情况下特别重要。列车重量和长度的增加将促使运量增长,列车运行次数减少,货物送达加速,并推迟线路改造的基建投资。但实践表明,如今货物列车的平均重量增长较为缓慢,这就影响了许多货运繁忙干线货 Improving the average weight of freight trains is one of the major tasks of improving railway operations. This is of particular importance in the context of the ongoing economic accounting and self-financing, as well as the increasingly heavy workload of railway technology. Increasing the weight and length of trains will result in an increase in traffic volume, a decrease in the number of trains operating, an acceleration of service delivery, and a delay in infrastructure investment in route alteration. However, practice shows that the average weight of freight trains nowadays grow more slowly, which affects many busy cargo lines
