【摘 要】近年来随着运输任务的增加,介西线介休至万安间单线区段的瓶颈限制愈发突出,已影响到介休站畅通。为释放通道能力,建议修建南同蒲线义安站至介西线万安站联络线,或对介休至万安站间进行复线改造,重新部署介休站與孝西站发挥作用,调整南同蒲线机车交路,提高介西线通道能力,实现介休支点运输均衡。

【Abstract】In recent years, with the increase of transportation task, the bottleneck limit of the single line section of Jiexiu to Wan ' an in JieXi railway is becoming more and more prominent, which has affected the smooth operation of Jiexiu station. To release the channel capacity, it is recommended to construct the connecting line from the Yian station in South TongPu railway to Wanan station in JieXi railway, or reconstruct the section from Jiexiu station to Wanan station, to redeploy Jiexiu station and Xiaoxi station, to make them play a role, then adjust the locomotive routing of south TongPu railway, to improve the channel ability of JieXi railway, so as to realize the equilibrium transportation of JieXiu pivot.

1 引言

介西线、孝柳线作为太原局集团公司的重要战略装车线,同时也是集团公司重要的空车储备基地,运输任务较为繁忙,但受介休站至万安站间单线区段以及介休站技检、接发能力的限制,通道能力不能满足出入列车的需求,造成介休站与介西线交换车流线等现象较为严重。为解决影响运输的瓶颈,提出修建义安站至万安站间联络线或对介休至万安进行复线改造的构思,达到提高介西线通道能力和保证南同蒲线畅通的目的。

2 既有线路布局

目前,介休站与万安站间为单线区间,两站间设四公里线路所,四公里线路所除连接介休站、介休工业站外,还通过义万疏解线连接南同蒲线义棠站,义棠站与万安站间通过义万联络线连接(如图)。在此布局下,南同蒲线中段向介西线排空效率最高,介西线装重后无论介休上行还是南同蒲下行列车均需经过四公里线路所,受介休站至万安站间单线区段限制严重,造成介西线出重能力严重受限。……
