Objectives
  • Increase the transport capacity of existing
    bridges by allowing axle loads up to 33 tons for
    freight traffic with moderate speeds
  • Increase the residual lifetime of existing
    bridges with up to 25
  • Increase the capacity for passenger traffic with
    low axle loads by increasing the maximum speeds
    to up to 350 km/hour
  • Enhance strengthening and repair systems
