Study On Operation Scheme Of Night Trains On Beijing-Guangzhou High-speed Railway

With the overall construction of the high-speed railways in our country, the transport for a long distance of high speed railways will gradually increase. The operation of night trains will lighten the transportation pressure on the existed main lines and high-speed railways, save the passengers’ travel-time and increase the social operation efficiency. So it has the great significance for the great-leap-forward development of the railways.Operation scheme is an important part in passenger transportation operation. But the high-speed railways in our country are still in the first stage and there is lack of systematic and feasible in the research on the operation scheme of night trains. At the same time, there is also lack of adequate reference in construction and operation organization of the Chinese high-speed railways. The high-speed railways in some developed countries are developed very well no matter on the technique or the theory about the high-speed railway. So the paper deeply studied the operation scheme of the developed countries and then does the research about the operation scheme in China.In order to establish the scientific and reasonable high-speed railway operation scheme of night trains, the paper analyses each factor influencing the operation scheme of night trains. On base of that, integrated and optimal model is built up after considering the two factors which are railway department gains and travelers expenditures. On the base of predicted OD passenger flow of Beijing-Guangzhou high-speed railway, the paper makes the final scheme by using the model. Combining with the confirmation car scheme of Beijing-Guangzhou high-speed railway scheme, the paper draws the night trains operation diagram in different comprehensive maintenance windows. Finally, the paper establishes the comprehensive evaluation index system of night trains operation scheme and takes the optimum operation scheme and operation diagram by using the method of the program evaluation and selection.Theory of making the plan and technical condition is provided for the high-speed railways and future high-speed railway network.
