为满足油菜花季旅游客流需求,兰新第二双线门源站需增加列车折返作业功能。文章基于现行规范及作业时间标准,对车站到发线、咽喉的全日与高峰小时能力进行了分析检算。经检算,在不增设立折线情况下,采用正接反发的方式,车站到发线与咽喉道岔能力,均能满足列车开行方案需要。

In order to meet the demand for tourist flow in the rapeseed flower season,Menyuan station of Lanzhou-Urumchi high speed railway needs to add train turn-back operation function.Based on the current norms and operating time standards,the full-day and peak-hour capacity of arrival-departure line and throat of the station is analyzed and calculated.It has been calculated that the capacity of the station arrival-departure line and the throat turnout can meet the needs of the train operation plan without the use of return lines.
