RSSB . Loading Requirements for Track Systems
Development, railway construction
Would you approximate an elastically bedded bar with a single-span girder? Probably not!
Nevertheless, in rail track engineering it is common to apply load models developed for the design and assessment of bridges as an approximation of loading regimes for rail tracks. FCP’s client questions the traditional approach and is interested in developing realistic load models for track designers.

„ FCP gets modern track construction off the ground “
Dr.techn. Lukas Moschen
Multi-body dynamic simulations have been performed to model the dynamic interaction of the coupled vehicle-track-soil domain. Comparison of numerical response quantities with readily available data extracted from measurements of the German railway project VDE 8.2 reveals the superior quality of the novel methodology.
Due to the proposed novel load model FCP sets the course for modifications of track construction standards to be able to meet the requirements regarding reliability and availability of public means of transport and traffic of the 21st century.
