Research in the field of train-bridge interaction is reviewed, with a particular focus on the vertical dynamic response of the bridge. The most influential system parameters are identified and discussed, providing a basis from which to establish an appropriate degree of complexity in train and track modelling. A two-level factorial experiment is presented. This is used to highlight the relative influence of train-bridge interaction in the train-bridge model, compared with variations in other key parameters. We distinguish those parameter combinations in the train-bridge system that lead to a significant reduction in bridge response due to the train-bridge interaction. The present survey fills an important gap in our existing knowledge by synthesising conclusions from the vast literature on train-bridge interaction. Moreover, the knowledge is related to the European design code's guidelines for dynamic bridge analysis. The conclusions are summarised to give a rough guidance on modelling choices for train-bridge interaction systems.
