Abstract： [Purposes] Heavy-haul trains are prone to safety accidents due to complex railway lines and significant fluctuations in longitudinal forces.By combining a longitudinal dynamics model with reinforcement learning algorithms，this paper proposes a reinforcement learning-based operation optimization algorithm for heavy-haul trains to reduce longitudinal force fluctuations and improve operational safety and efciency.[Methods] The longitudinal force constraints were considered and abstracted as a reinforcement learning problem. The state space was defined to include speed， position，time，accumulated brake release time，and the control forces from the previous two stages.The action space included train control force and air brake decisions.Aiming to improve transportation eficiency and reduce energy consumption while ensuring longitudinal forces and operational safety meet requirements，a Qlearning algorithm was employed to design an inteligent operation strategy optimization method for heavy-haul trains.[Findings] Simulation results demonstrate the effectiveness of the proposed longitudinalforce evaluation model.In the optimization of long downhillsections，the optimized strategy with longitudinal force constraints significantly reduced the maximum coupler force while maintaining high transportation efficiency.[Conclusions] The reinforcement learning-based operation optimization algorithm for heavy-haul trains proposed in this paper achieves safe and efficient train operation under longitudinal force constraints.
