The RUN2RAIL project explores an ensemble of technical developments for future running gear, looking into ways to design trains that are more reliable, lighter, less damaging to the track, more comfortable and less noisy. The project develops across four thematic Work Streams: (1) Innovative sensors & condition monitoring, (2) Optimised materials & manufacturing technologies, (3) Active suspensions & mechatronics, (4) Noise & Vibration. KTH worked in work streams (2) to (4). In (2) the general feasibility of using composite materials was investigated. KTH was leading (3) and mainly developing a concept for an innovative two-axle vehicle with only one suspension step and active vertical and lateral suspension as well as active wheelset steering. We also contributed to a possible future homologation strategy for rail vehicles with active suspension. In (4) KTH mainly worked on theoretical and experimental characterisation of suspension elements with respect to vibration transmission.
