为了使运能适应运量不断增长的要求,目前我国某些以煤运为主以及通过能力紧张的双线铁路上,开行了两列合并的组合列车,并已从试运转逐步列为图定列车的组成部分,成为目前和今后“扩能”的重要途径。为了搞清开行组合列车对区间通过能力和输送能力的影响,正确评价开行组合列车的经济效益,本文拟就双线铁路开行组合列车的扣除系数、区间通过能力和输送能力的计算方法及其影响因素,提出一些初浅看法,愿与同行专家商讨。一、列车追踪间隔时间的确定目前我国开行组合列车的区段,均采取客货混跑、组货与普货并存、组合列车的运行速 In order to enable the transport capacity to meet the growing demand for transportation, some of the combined railway trains that are mainly coal-based and through two-lane railways with limited capacity have been gradually listed from commissioning to plans As part of the train, it has become an important way for “expansion” at present and in the future. In order to find out the influence of the combined train on the passing capacity and transport capacity of the train, and to correctly evaluate the economic benefits of the combined train, this paper proposes to calculate the deduction coefficient, the method of calculating the passing capacity and the conveying capacity of the combined train on the two- Factors, put forward some initial ideas, is willing to discuss with peer experts. First, the train tracking interval to determine At present, China’s opening combined train section, take the mixed fleet, group cargo and general cargo coexist, combined train speed
