Disclosed in the present invention are a heavy-haul train and a longitudinal dynamics traction operation optimization control system and method thereof. A model prediction function is added to a locomotive wireless double heading system so as to suppress large longitudinal impulse that is likely to be generated when the operation speed of the heavy-haul combined train is regulated, especially when the heavy-haul train is switched at a grade change point working condition, and the major potential safety hazard that affects the safe and stable operation of the heavy-haul combined train is avoided. In a distributed dynamic marshalling mode of the heavy-haul combined train, the requirements for the difference between the tractive force and the regenerative braking force of a master locomotive and slave locomotives of a multi-locomotive under the same working condition are predicted by the model, the amplitude of the power for the traction and the regenerative braking of the master locomotive and the slave locomotives is reasonably adjusted, and asynchronous control of the train under different working conditions is gradually achieved, so that the purposes of optimizing the dynamics performance of the heavy-haul combined train and reducing the longitudinal impulse of the heavy-haul train are achieved, and the operation of the train is guaranteed.
