• Focus on new materials (WP4) will investigate whether new material and manufacturing techniques are able to improve performance.
  • Optimisation of wheel/rail interface (WP4) will minimise wear, and hence resulting noise.
  • Validation of design concepts (WP6) will ensure that the solutions are practicable.
  • Evaluation of design integrated design (WP7) will quantify the impact (economic, performance, etc.).
