Examination of railway track dynamic models capabilities against measured field data

The performance of railway track under dynamic loading is extremely complex due to the interdependent and sometimes non-linear behaviours of track components. Many and varied computer models of train-track dynamics have been developed around the world to try and analyse these behaviours. To compare, test and validate the capabilities and outputs of six available computer models, an evaluation exercise was undertaken to benchmark the participating models against each other and against measured field data collected at a track test site in Victoria, Australia. The outcomes of this paper will assist railway engineers in selecting an appropriate model for their requirements.
