The numerical model for train track interaction is based on a time domain dynamic finite element model. Due to the unbounded nature of the soil the truncated boundary of the finite element domain is modelled with the scaled boundary finite element method, which is a semi-analytical approach. The application for a heterogeneous track along the track line is exemplified by a track with a bridge structure, where close attention is paid to the wheel-rail contact force. The results indicate that the wheel-rail contact force is not symmetrical around the bridge structure and an optimisation in terms of a backfilling area and under-sleeper-pads can improve such a transition.
