在幅员辽阔、资源丰富的国家,铁路货运列车趋向拉得多。多拉的重要技术条件之一是车站到发线的有效长度(以下简称站线长度)。从铁路发展的历史过程看,随着列车的不断加重和加长,车站的站线长度相应地由短到长。到了近代,在不同国家和地区的铁路系统,各条铁路线的运输要求、技术装备和组织方法不尽相同,车站站线长度扩大了差异。北美铁路列车拉得最多,站线长度往往长达2公里以上,而无统一标准。一些线路区间铺设无作业的会车线,类似双线插入段,长度不一。澳大利亚、巴西、南非等国原有路网的
In a vast and resource-rich country, rail freight trains tend to be much more advanced. Dora one of the important technical conditions is the effective length of the line to the station (hereinafter referred to as the station line length). From the historical process of railway development, as the train continuously aggravates and lengthens, the station’s station line length is correspondingly short to long. In the modern times, the transportation requirements, technical equipment and organization methods of railway lines in different countries and regions varied in length, and the length of the station line had widened. North American railway train pulled up, the station line length is often up to 2 km or more, but no uniform standard. Laying some lines of non-operating session of the car line, similar to the two-lane insertion section, the length of different.
