Project description

EN 14363:2016 allows to perform complemented simulations for the acceptance of railway vehicles. Track geometry is an important input parameter and the requirements regarding track geometry data depend on the envisaged speed.
Track recording cars are used for maintenance purposes only. No track geometry measurement system in Europe is currently able to meet the demanding requirements for simulations. Therefore, costly, time-consuming and capacity-consuming track geometry recordings have to be carried out specifically for simulation purposes, to fulfill these particular needs.
Opportunities for an extension of the scope and an harmonisation of not only track recordings are investigated, but other on-board measurement systems in order to allow high output recording cars to collect the requested geometry data and other practical measurements on track condition both for maintenance and for simulation purposes. Considering the more and more frequent use of simulation, especially for virtual homologation (still partial) of vehicles, high benefits in term of time, cost and capacity savings are expected, as well as a higher level of reliability of the simulation works.
