ABSTRACT: In view of the waste of transport capacity caused by a single train formation mode due to the uneven temporal and spatial distribution of passenger flow in the early stage of intercity railway opening, starting from the train operation cost, the operation schemes of large and small marshalling trains with various stop modes are studied. Taking the minimization of train operation cost as the objective function, taking the number of running trains and parking scheme of large and small marshalling trains as decision variables, and comprehensively considering the constraints such as train section full load rate and OD service frequency, the operation scheme model of large and small marshalling trains is constructed. The genetic algorithm is used to solve the problem, and the operation scheme of large and small marshalling trains in the whole day is obtained. Taking Guangqing intercity railway and Guangzhou east ring intercity railway as an example, compared with the current train operation scheme, the large and small marshalling train operation scheme with multi stop mode can reduce the train operation cost by 59%, and the average daily section load ratio can be increased from 0.2888 to 0.8665, which shows that the large and small marshalling train operation scheme with multi stop mode can effectively reduce the train operation cost and improve the section full load rate.
