This was also the case recently in Switzerland. The Rhaetian Railway makes railway hearts beat faster. The track is one of the most beautiful in the world, and the Bernina and Albula lines are even UNESCO World Heritage Sites. In addition to the picturesque landscape, the technical requirements are fascinating. Typical for the metre gauge track are curves up to 45 m radius and gradients up to 70 &permil;. The Allegra multiple-unit train made by Stadler AG, which is used on this line in various vehicle configurations, is perfectly tailored to these high line requirements. In order to test the running characteristics of different train compositions under special operating conditions, PJM was commissioned with running tests.<\/p>\n<p>The project was carried out in several parts by the experienced system specialist from Austria:<\/p>\n<ul>\n<li>In the preliminary stage, the wheel-rail forces as well as occurring buffer forces were determined by simulations. In this way, critical conditions or constellations could be resolved computationally. Another advantage is that this keeps the metrological effort to a minimum.<\/li>\n<li>Instrumented wheel sets, accelerators, transducers as well as measuring buffers were prepared in the usual way at the company's location in Graz and then installed on the test vehicle at the RhB main workshop in Landquart.<\/li>\n<li>The measurement campaign was carried out on the track between Poschiavo and Alp Gr&uuml;m. In real operation, the running behaviour was tested under increased operating forces. The test runs took place in November 2022. The data analysis and report were recently completed.<\/li>\n<\/ul>\n<p>Further information in the media release: <a
