铁路货车是铁路货物运输的核心装备,重载、快捷是当今世界铁路货物运输的重要标志和趋势,也是提高铁路货运能力的有效手段。2000年以来,我国铁路货车技术水平迅速提升,综合技术水平已达到了国际先进,但既有提速重载技术难以满足社会对铁路货运快速增长的需要,创新重载快捷技术成为我国铁路货运发展的必然
Railway freight wagons are the core equipment of railway freight transportation. Overloading and expediting are the important signs and trends of railway freight transportation in the world at present. They are also an effective means to improve the railway freight transport capacity.
