摘　　要：研究目的:客运专线建设成网后将承担主要的旅客运输任务,实现客货分线运输,既有线的运能紧张局势将得到缓解,因此,有必要调整既有线运输组织以适应变化趋势。本文特对既有线客货运输产品的定位进行探讨。研究结论:客运专线建设成网后,既有线上大量客运站、客货运站的客运作业量减少或转变为货运站。既有线线路上的货物运输能力释放,且线路上列车种类减少、列车间速度差减小,货物列车的旅行速度提高,旅客列车的扣除系数也有一定程度减小,既有线应该根据变化情况充分发掘既有线运输能力,以适应运输需求增长的趋势。同时,既有线也要协调好与客运专线的关系,调整传统的运输组织原则,对既有线的各种基础设施进行改造,加强对货物运输服务质量的重视。此外,既有线铁路应该抓住发展机遇,发挥自身优势,准确把握市场目标,发展特色客、货运输产品,提高竞争力,适应运输发展的要求。Research purposes： The Passenger dedicated line （PDL） mainly undertakes the passenger traffic to realize separating the passenger traffic and freight traffic into different railway lines and relieve the situation of the insufficient transport capacity of the existing railway line, so it is necessary to adjust the traffic organization mode of the existing line to adapt to this change trend. This paper discusses the orientation of the passenger and freight traffic products of the existing line. Research conclusions： After the passenger dedicated line network is formed, the passenger traffic service of the existing lines will reduced much, and plenty of passenger stations and mixed passenger and freight service stations will he changed into freight stations. In that case, the freight traffic capacity of the existing line will enhance, the train type on the line will reduce, the speed difference between trains will lower, the travel speed of train will enhance, and the coefficient of removal for scheduling one passenger train will reduce, so based on this situation, the existing line should explore its traffic capacity to meet the increasing traffic demand. At the same time, the existing line should well coordinate the relation between it and the passenger dedicated line, adjust its traffic organization principle, upgrade its infrastructure, pay more attention to the quality of freight traffic, grasp the development chance, full give play to its advantages, accurately aim at the market target, and develop its characteristic passenger and freight traffic products to enhance its competition capacity for meeting the increasing traffic demand.
