Assessment of the safety against derailments of trains of of the historic fleet of Basel Transport (BVB)

 

Customer: Basler Verkehrs-Betriebe (BVB), Switzerland

Project tasks:

  • Recording of vehicle data of the historical fleet 

  • Clustering of the vehicles 

  • Recheck of indentation-stiffness of the Velogleis-rubber by means of measurements on site ;

  • Calculation of guiding forces, using a simplified theoretical approach, considering track twist and re-calculated torsional stiffness of the bogies with their suspensions of leaf-springs, friction in wheel/rail contact and flange parameters;

Technical data:

  • System "velogleis" 

  • Historical fleet 

  • Numerical evaluation model
