铁路编组站中产生的折角车流对车站的咽喉区和运输能力的影响十分明显。丰西枢纽内的北环线由于折角车流的通过,北部咽喉区每天被横切26次之多,严重影响了枢纽能力。丰台西站利用既有设备改造后,对折角车流进行疏解、分流,提高丰台西站整体能力,并为大秦线增运提供一定的能力储备。 Angular traffic generated by the railway marshalling station traffic station on the throat area and transport capacity of the impact is very obvious. The North Ring Road in the Fengxi Pivotal, due to the passing of angled traffic, traverses the throat area in the north by more than 26 times a day, seriously affecting the hub capacity. Fengtai West Railway Station using existing equipment after the transformation, the angle of the car stream to ease, diversion, improve the overall capacity of Fengtai West Station, and provide capacity for the Daqin line to increase transport capacity.
