在现有站线长度及允许的列车最大编组重量的前提下,采用大吨位货车是提高铁路运输能力的有效手段之一。全苏铁路运输科学研究院对货车轴重提高到250千牛的可行性进行了广泛的试验以及技术和经济分析。从长远看,这种轴重适应于煤炭运输,能提高运输效率,特别是当使用T限界车辆时的运输效率。为检验这种货车的动力性能及其对线路的影响,乌拉尔车辆制造厂试制了载重为750千牛的敞车的样车。该车采用轴重为250千牛的二轴转向架(图号为546.00.000.080),自重为25吨,车体容积为85米~3,每延米载荷为70.18千
Under the premise of the length of the existing station line and the maximum weight of the train allowed, adopting a large tonnage truck is one of the effective means to improve the railway transport capacity. The All-Su-Tuk Railway Academy conducted extensive tests and technical and economic analyzes on the feasibility of raising the axle load of a truck to 250 kN. In the long run, this kind of axle load is adapted to coal transportation, which can improve the transportation efficiency, especially when T vehicles are used. To test the power performance of the truck and its impact on the route, the Ural car factory prototyped a prototype of a gondola for a 750-kiloton gondola. The car with a shaft weight of 250 kN biaxial bogie (drawing number 546.00.000.080), weight 25 tons, the body volume of 85 m ~ 3, the load per meter was 70.18 thousand
