The scope of the V/T SIC is defined in its remit and aims to:

  • Define the geometry condition of the wheel/rail interface
  • Set out permitted track geometry, including curve radius, installed cant, vertical curvature
  • Define the permitted track conditions for the type of track, namely Mainline
  • Identify the allowable wheelset parameters, such as gauge, conicity, profile, axle load, for the trains that operate on the network
  • Maintain the wheel/rail interface within the prescribed limits and ensure safety of the railway
  • Implement processes to ensure sustainability of the railway
  • Ensure systems exist for seasonal maintenance activities and revised to account for seasonal variation
  • Utilise systems to monitor the condition at the wheel/rail interface. Data collected by these systems is to be analysed and distributed to the appropriate party for the monitoring of performance and programme rectification activities.
