Research project for an innovative concrete sleeper

Customer: Swiss Federal Office for the Environment, Switzerland

Project tasks

  • Experimental modal analysis on different concrete sleepers
  • Computational modal analysis FEM
  • Measurements in specially built test track
  • Measurements of TOR and sound radiation
  • Design and analysis of two sleeper types
  • Manufacture of sleepers by project partners

Our Approach

The new concrete sleepers were developed in cooperation with the Swiss concrete element manufacturer Vigier Rail. The existing sleeper types were first examined and analyzed using measurement technology and the parameters influencing the acoustics were analyzed.

Customer benefit

With this research project on an essential element of the track superstructure, PROSE wants to advance the industry – with less noise and simultaneously low wear and tear or lower life cycle costs. This benefit both the affected residents and the infrastructure contractors.
