When two or more lines of urban rail transit share the same train depot and the train types are compatible, the sharing of train depot provides a basis for the preparation of a unified train turnover plan of multiple lines. There are some differences in the directional characteristics of passenger flow on urban rail transit lines, which provides an optimization opportunity for the coordination and complementation of train utilization between lines. In order to improve the utilization rate of urban rail transit train stocks and reduce the operation cost, we makes use of the difference in the direction of urban rail transit passenger flow under the premise of sharing train depots, takes the minimum number of train stocks required as the optimization objective, compiles a unified multi-line train stocks turnover plan. Then we calculates the number of saved trains, so as to reflect the sharing effect of train depot. Finally, the effectiveness of the optimization method and algorithm is verified by a specific example. The results show that: when the two lines connected by the shared depot run non-paired diagram, some trains can go to another line through the depot to continue to perform the task, so as to save train stocks, and the more obvious the imbalance of passenger flow in different directions, the more trains can be saved.
