PrudHomme - Review of the Prud'Homme criterion for validity with current track technologies especially in very tight curves

The aim of the service is the scientifically substantiated verification of the validity of the the cross-track displacement limit value according to Prud'homme for the roadworthiness approval of rail vehicles rail vehicles, in particular for curves with radii of less than 250m ('test area 5'). With theoretical and experimental proofs, the limit value is compared with the state of the state of the art in track design and maintenance, and its validity is verified. verified. A modification of this limit value corresponding to today's limit value is being developed.
