Technology

Plasser InertialTrackGeometry

To assess the quality of the track geometry produced following maintenance, the inertial measurement unit (IMU) records and analyses the most important track parameters. The unit is integrated into the machine and ensures the track geometry is completely measured.

The non-contacting track geometry measuring system records the actual track geometry by means of 3D space curves. As a result, deviations are immediately visible.

This modularly expandable system is already in operation on more than 80 track inspection vehicles and tamping machines around the globe, allowing for optimal integration into your worksite logistics.

Added value

Plasser InertialTrackGeometry

  • Precision and quality
    • Track geometry measurement in conformity with EN 13848
    • Highest accuracy irrespective of the direction of travel and speed
    • GPS ensures the highest precision for locating measuring data
    • Highly accurate measurement under real conditions (with real axle load)
    • Completely replaces the mechanical recorder chord
    • Records track geometry faults of the following wavelength ranges reliably: D1 (up to 25 m), D2 (25 m up to 70 m), D3 (70 m to 150 m longitudinal level or 200 m lateral position – only with the high-speed system)
  • Efficiency and flexibility
    • Can be used during regular train operation at up to 160 km/h without track possessions
    • Can be used on different carrier vehicles (track inspection vehicle, maintenance machine)

    • A carrier vehicle can fulfil several tasks:

      • Pre-measuring

      • Work documentation
      • Inspection run
    • Can be used on plain-line tracks and in turnouts without interruptions
    • The machine can synchronize recorded track geometry data directly and automatically with the cloud (tmOS) (no need for manual data transmission).
  • Expandable system
    • Possible to integrate the Plasser ReferencedTrackGeometry

    • The measuring values can be transferred directly to the SmartALC Automatic Guiding Computer to generate working parameters

    • Interfaces to many modern planning tools allow track geometry data to be processed optimally.
  • Cost efficiency
    • The IMU system doesn’t require servicing

    • The IMU system doesn’t need to be recalibrated

    • There are low costs throughout the entire life cycle
