由于货运量的增加使波兰铁路的货车构成发生了变化,首先是转向架货车部分的增加,如下表所示。除了象棚车、敞车和平车等标准型通用货车之外,还要增加大量的专用货车。由于货车构成的改变、车辆数量的增加和使用的强化,必须在改善车辆修理组织和工艺的同时,对货车修理工厂进行扩建和现代化。 Due to the increase in freight volume, the composition of the Polish railway truck has changed. The first is the increase in the part of the bogie truck, as shown in the following table. In addition to standard general cargo vehicles such as box cars, gondolas and peace vehicles, a large number of special purpose trucks have to be added. Due to changes in the composition of trucks, the increase of the number of vehicles and the enhancement of their use, it is necessary to expand and modernize the truck repair factory while improving the organization and technology of vehicle repairs.
