近年来,苏联在开行重载货物列车运输方面发展很快。据1983年统计,重载货物运输在苏联货运中所占比例已增长到8～10％。其牵引吨位的增长也超出预料,目前已达6000～10000t。1984年还进行了30000t运煤重载列车的运行试验。根据苏联铁道运输发展规划,预计今后牵引吨位还会提高。机车车辆制动装置的技术性能对铁路运营工作指标具有重大影响。在重载货物列车的制动方面,苏联不仅积累了丰富的经验,采取了较先进的技术,而且已将开行重载列车的制动机整备和操纵经验制订成文,
In recent years, the Soviet Union has been developing rapidly in the transport of heavy-haul freight trains. According to 1983 statistics, the proportion of the heavy-haul freight transport in the Soviet Union has increased to 8-10%. Its traction tonnage growth also exceeded expectations, has now reached 6000 ~ 10000t. In 1984, 30,000 tons of coal heavy haul trains were also tested. According to the Soviet Union’s railway transport development plan, it is expected that the towing tonnage will increase in the future. The technical performance of the locomotive and vehicle brake device has a significant impact on the railway operation indicator. Regarding the braking of heavy goods trains, the Soviet Union not only accumulated rich experience and adopted more advanced technologies, but also formulated the experience in the preparation and handling of braking machines for heavy-haul trains.
