Rolling stock and rail structures

Checking the compliance of rolling stock movements on rails structures: bridges and tunnels of a given route for type approval purposes.

Tests objectives

Determine running and clearance gauge conditions of a new rolling stock or new rolling stock configurations in relation to the structures (bridges and tunnels) on a particular ailway network.

Tests facilities

  • Tools for calculating the loads exerted by new rolling stock on rail structures – static and dynamic
  • Measuring systems used at tunnel oportals and for geometric studies (Elise)
  • Instruments installed on structures to assess the impact of passing trains (under test or not)

Testing norms

NF EN 15528 – Line categories for managing the interface between load limits of vehicles and infrastructure

Eurocode 1 – Part 2 and Annex A2
