Trackside Measurements

• Perform and supervise dynamic measurements on passing trains
  – Physical phenomena: Vertical and lateral forces exerted by the wheels on rails, stresses, forces and displacements on track components, structure deflection, accelerations on the rail, sleepers, track bed, etc.
  – Aerodynamic phenomena around the train: Air velocity along the train,pressure in tunnels and in the open air
  – Acquisition and use of data: Identification and characterization of traffic, natural frequencies and damping calculations, automating the acquisition and use of data
  – Remote monitoring of dynamic behaviour
• Perform and supervise measurements of slow phenomena
  – Meteorological parameters
  – Development physical parameters over time – on track or on structures
  – Levelling checks, settlement monitoring
  – Measurement of neutral temperatures of CWR (Continuous Welded Rail) – nondestructive method VERSE
  – Lateral track resistance
  – Remote monitoring of slow phenomena
