Safe operation of the train under draughting mechanics was probed into. A simulation system for safe operation under different running conditions and train parameters was developed. The system structure and the calculation model for locomotive working between given stations and its elicitation were emphatically discussed. The heuristic algorithm for determining the control handles and braking the train at each time step was described in detail. Based on characteristic data for electrical locomotive, a case analysis on given background was given. Preliminary result has been achieved on train operation under confirm route condition. With the aid of simulator, the algorithm could provide fast simulation results and expediently human interference in practice.
