The invention discloses a train punctuality energy-saving operation method based on a dynamic programming algorithm. A train model and an operation environment of the train model are constructed by setting train operation line data and train parameters; train punctuality and train traction energy consumption are taken as optimization objectives; an energy-saving optimization model for train operation is established, constraint conditions such as travel time, speed limitation, train maximum acceleration and deceleration and the like are fully considered, a train operation constraint function, namely the constraint conditions of the energy-saving optimization model, is established, the optimization model is solved by utilizing a dynamic programming algorithm, and an optimal train operation strategy of a train is obtained. According to the method, the train energy-saving optimization precision is effectively improved, the optimization speed is high, the method has the advantage of wide optimal solution search range, and the train energy consumption is reduced.
