This paper presents a three dimensional numerical model which is can be used to
investigate the effects on the track and in its vicinity due to a train passage. 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.
