Principles of Creation of an Optimal Train Motion Trajectory

The main criteria and types of problems of constructing the optimal trajectory of the train are presented. The reasons for the emergence of time reserves for passing track sections by train related to the peculiarities of developing a train schedule are given. The energy efficiency of train speed reducing by decreasing the used running positions of the controller of the driver or switching to idle when there are time reserves in the train schedule is substantiated. The concept of "equivalent energy/fuel consumption" and a methodology for its determination are proposed. The proposed concepts allow to evaluate the reduction in energy consumption when passing the same section with different speed and time. The basic techniques of driving a train, due to which an effective speed reduction is achieved, are considered. The restrictions and particularities of driving trains, which should be taken into account when implementing the methodology and algorithm for determining the optimal trajectory of a train, are given.
