<p>The safe driving and operation of trains is a necessary condition for ensuring the safe operation of trains. In particular, heavy-haul trains are characterized by the difficulty in driving and operation. Considering the uncertainties in train driving and operation, this paper analyzes the relationship between the safety of heavy-haul electric locomotive-hauled trains and driving and operation. It studies the auxiliary intelligent driving safety operation control methods. Through <i>K</i>-means to identify the characteristics of drivers’ driving manipulation, the hidden Markov model adaptively adjusts the train driving and operation sequence, and conducts auxiliary driving reconstruction for heavy-haul locomotive driving and operation. Based on the train running curve and the locomotive traction/braking characteristics, it smoothly controls the exertion of the traction/braking force of heavy-haul locomotives, thereby optimizing the driving safety control of heavy-haul trains in the vehicle-environment-track system. Finally, the train operation simulation and optimized driving verification are carried out by simulating some track sections. The results show that the proposed method can correct and pre-optimize driving operations, improving the smoothness of heavy-haul trains by approximately 10%. It verifies the effectiveness of the proposed train assisted driving control reconstruction method, facilitating the smooth and safe operation of heavy-haul trains.</p>
