Railway bridge dynamics: development of a new high-speed train load model for dynamic analyses of train crossing

In 2019, the German Federal Railway Authority commissioned the consortium TU Darmstadt, KULeuven, AIT-Austrian Institute of Technology and REVOTEC to develop a new dynamic load modelfor high-speed railway bridges. It aims to cover the envelopes of the dynamic train signatures andacceleration responses for all currently operating trains and the current HSLM (high-speed loadmodel), given in the Eurocode. In addition, the development of the new load model should alsoinclude possible configurations of fast freight trains and future train configurations. An overview ofthe planned content of the research project and selected results of the current work will bepresented.
