This study compares the two-layer model and three-layer model in the coupling analysis of the vehicle–rail–viaduct systems, especially for the vertical vibration investigation. This study applies dynamic flexibility in establishing the dynamic model of vehicle–rail–viaduct in frequency domain through the wheel–rail interaction and interaction model between rails and viaducts. By simplifying the subsystems of vehicles, rails, and viaducts in order to obtain two-layer model and three-layer model, the dynamic responses are hereinafter analyzed for the influences of subsystems to the final vibration responses. The results shall suggest the prediction of dynamic responses for the vehicles, rails, and viaducts.
