南阳西站通过能力分析与提高措施

Carrying Capacity of Nanyangxi Railway Station and Optimization Measures

根据目前南阳西站的站场布局、线路运用情况结合接发车作业时间标准,对南阳西站到发场现有通过能力进行计算,针对换挂机车作业量大、车流到达不均衡、列车风压不一致、站场设置不完善等影响南阳西站到发场通过能力的因素进行了分析,提出优化机车担当交路、统一列车风压、提高列车接发效率等优化措施。此外,结合宁西线近期货运增量的需求,提出了组织车流均衡运输、优化南阳西站场布局、加强日常作业组织等建议,对提高南阳西站整体作业能力提供了参考。

The current carrying capacity of the receiving-departure yard of Nanyangxi Railway Station was calculated with due consideration given to the current yard layout and line utilization of the station and the time standard for receiving and dispatching operations. Then, this paper analyzed the influencing factors on the carrying capacity of the receiving-departure yard of Nanyangxi Railway Station, namely, a large number of locomotive coupling operations, uneven arrival of the traffic flow, inconsistent traininduced wind pressure, and incomplete yard arrangement. The paper further proposed various optimization measures, including optimizing the routes locomotives undertook, unifying train-induced wind pressure, and improving train receiving and dispatching efficiency. In addition, to meet the recent demand of Nanjing-Xi’an Railway for an increment of freight volume, the paper also put forward a number of suggestions, such as organizing balanced transportation of the traffic flow, optimizing the yard layout of Nanyangxi Railway Station, and strengthening daily operation organization. This paper provides a reference for improving the overall operational capacity of Nanyangxi Railway Station.
