Simulation algorithm for multi-train movement with Fixed Automatic-Block System

This paper analyzes the characteristics of the trains under Fixed Automatic Block System in detail. Based on the model of the single train, the model of multi-train operation with precise train dynamic calculation is founded. The model can clearly describe the running state of the proceeding train and the impact of the signal change on the following train´s control strategy. New algorithm is discussed about how to determine the control modes and handles through considering dynamic variation of signal aspect and corresponding speed limits. At last, it gives some simulation results to show that the simulation methods of the multi-train operation can efficiently reflect the moving interference between successive trains and singling system.
