苏联伏尔加河沿岸铁路局为提高单线区段的通过能力,采用了加速放行客、货列车的新方法,即在单线成束追踪运行图模拟的基础上,建议在一定的周期内,先在一个方向上,后在其反方向上,强化正线单方向列车的放行。铺图时,将单线区段分成若干时间带,时间带内列车的运行组织按双线反向行车所采用的原则和安全规定办理。采用这种方法,可保证无交会快速放行列车,或大大减少其交会次数。
In order to improve the capacity of single-lane section, the Soviet Bureau of Railways on the Volga River adopted a new method of accelerating the delivery of passenger and cargo trains. On the basis of the simulation of the single-track bunching tracing diagram, it is suggested that in a certain period, Direction, after the opposite direction, strengthen the positive one-way train release. Shop map, the single-line segment is divided into a number of time zones, the time zone train operation organization by two-lane reverse travel principles and safety regulations apply. In this way, it is guaranteed that the train will be released quickly or the number of rendezvous will be greatly reduced.
