With the expanding scale of China's high-speed railway network, the increase of new lines, and the increase of train density, the existing layout, and maintenance capabilities of the EMU operation depot have been difficult to meet the operational needs of the high-speed railway network, so it is necessary to combine the network planning of high-speed railways to optimize the layout of new EMUs in advance. In this paper, the influence of new lines and exiting lines on the layout is analyzed and a multi maintenance spots optimization model for EMU operation and maintenance are built by applying multi-depots vehicle routing problem (MDVRP) with resource constraints. Then, taking the high-speed railway network in a certain area as an example, this paper designs two layout schemes for the operation depot, and finally the recommended layout scheme of EMU for this region is given by calculating and comparing the use of EMU in the short and long term.
