A new moving train–track interaction model is shown in the paper to accurately and efficiently determine long-term high-speed train–track interaction dynamic response. In this model, the rail is represented with a reduced beam model (RBM) and the slabs mainly affected by the train–track interaction are modeled with four-node Kirchhoff-Love plate elements. The fastenings are modeled with spring-damper elements and the Concrete Asphalt (CA) layer is modeled with a Winkler foundation. Since only a small part of the rail and a few slabs from the whole slab track are included, the present model has fewer degrees of freedom than the traditional model using the modal superposition method and the simulation time is significantly decreased. The present model is validated by a long-term train–track interaction case where the results are compared with those from the traditional method. The simulation results show that the present model is accurate and efficient and has great advantages in solving high-speed train–track interaction problems.
