With the development of high-speed railways in the last decade, the dynamic behavior of trains and bridges has been studied more thoroughly. However, it is difficult to find papers in the scientific literature about the lateral response of highspeed trains travel over long viaducts with high piers. In order to evaluate the riding comfort or vehicle dynamic response of a train over this kind of bridges, an efficient numerical dynamic interaction model of the train-bridge system was developed and checked. In that model, a three-dimensional multi-body train and a finite element bridge system are considered. Track irregularities and wheel-hunting movement are taken into account as the system lateral excitation. In this paper, the influence of pier height on the response of train and bridge is also studied. Continuous bridges, straight and constant section deck viaducts with variable height and tapered piers are studied. The height of the viaduct tested range between 40 and 100 metres.
