铁路编组站由于调车驼峰广泛采用机械化、自动化等新技术后解体能力有很大提高,调车场尾部的编组能力就成为控制整个编组站改编能力的关键。为解决这个问题,各国采取了不少办法,如考虑调车场部分股道直接发车,以减少尾部牵出线的转线作业。但这种方式必须在单组列车多,列车重量小,行程短的情况下才比较有利,英国采 The marshalling yard in railroad marshalling maneuvering system has been greatly improved in disassembly ability due to extensive use of mechanization and automation of shunting maneuvers. The marshaling ability at the tail of yard yard has become the key to controlling the maneuvering ability of the entire marshalling yard. To solve this problem, many countries have taken many measures, such as considering the yard part of the shares of the road direct departure to reduce the tail pull line transfer operations. However, this approach must be more than a single train, the train weight is small, the trip is relatively favorable circumstances, mining
