Abstract: Aiming at the problems of limitation of transportation ability, running heavy haul train was studied. The model of train longitudinal force which mainly involved train couplers gap and air resistance was established to study forces of train couplers by using Matlab. The synchronous control capability was evaluated on the simulation, then the Markov strategy was established to optimize the synchronous wireless transmission. The experimental results and data of 1+1+1 ten thousand tons train were compared with the simulation results. The results indicate that they are reasonable and it shows that applying optimized strategy in railway lines is feasible. Synchronous control capability of heavy haul train which contained Markov strategy was greatly optimized. Then the foundation of further improving synchronous control capability is built.

Key words: heavy haul train; mathematical model; simulation model; max forces of train couplers; Markov strategy
