怀衡铁路运营合理分工与旅客列车开行方案优化设计

怀衡铁路是2008年12月开通客运运营的快速铁路，优化运输组织对提高其运营效益有重要作用。在对怀衡铁路的线路情况、路网位置和沿线地区经济社会状况分析的基础上，论述了怀衡铁路的路网分工和列车开行方案优化的原则与方法，结合路网已有关联旅客列车开行情况与沿线客流条件，从跨线列车、半跨线列车、本线列车三个层次优化设计了相应的列车开行方案，优化方案符合怀衡铁路的客流实际，部分结论已应用到新制定的列车运行图中。最后，对进一步提升怀衡铁路的运营效益提出了相应的建议。

Reasonable Division and Optimal Plan of Passenger Trains Operation of Huai-Heng Railway

Huai-heng railway is an express railway which opened passenger transport in December 2018. Optimizing transport organization plays an important role in improving its operation efficiency. Based on analysis of the location in railway network and technical conditions of the line, the regional economic and social situation along the railway line, optimizing principle and method of the line operation division and train plan are discussed. Combined with associated passenger trains and passenger flows, the optimal scheme of crossing trains, part-crossing trains and line trains are hierarchically designed, the optimization trains scheme accords with passenger demands, and the results have been partly applied to the new trains diagram. Finally, some suggestions are put forward to further improve the operation efficiency of huai-heng railway.
