PROSE at the XIX International Wheelset Congress
PROSE has participated at the XIX International Wheelset Congress, which took place between the 16-20th of June in Venice, Italy. The IWC, held every three years, is the leading technology interchange event for the world railway industry. The congress was attended by delegates worldwide and was an opportunity for us to share experience as well as knowledge on the various topics discussed.
During this 19th edition, we also had to the opportunity to hold a presentation about a feasibility study carried out on noise and weight reduction. Dr. Rolf Paradies, Engineer Simulation FEA at PROSE, in fact presented the study “Towards Noise and Weight Reduction by Application of FRP wheelsets for Freight Cars”.
Railway noise is often a nuisance to people living near railway lines. In particular, the operation of freight wagons at night causes significant disturbance, which is a major problem in the development of rail freight transport. The dominant source is mostly the rolling noise, which is generated by the roughness at the wheel-rail interface and is radiated in addition to rails and sleepers in particular by the wheel.
Therefore, PROSE proposed to the Swiss Federal Office for the Environment FOEN (Bafu) a research project investigating the possibility of noise reduction in freight wagons through the use of Carbon fibre reinforced composite (CFRP) wheelsets. PROSE suggested this material because of its experience in implementing FRP materials in railway structures. You can find more information about this on our factsheet.

Montreux Berner Oberland Bahn AG (MOB) commissions PROSE for the development of gauge-changing facility in Zweisimmen
Montreux Berner Oberland Bahn AG (MOB) commissioned PROSE for the development of this gauge-changing facility. PROSE’s tasks included the mechanical and control engineering development of the plant, the design with preparation of manufacturing documents and supplier specifications, the strength calculation, the development of the software including tests and RAMS analysis for the ramp control, the supply of a control cabinet, tests of the complete assembly with the signal box and the hydraulic system as well as the support in supplier management and approval issues.
