As-built track survey at its best.

Extension of a revolutionary measuring principle

  • Long-chord method with only one measurement trolley for as-built survey
  • Combined survey of relative and absolute track geometry
  • Unrivalled survey performance up to 5000 m/h
  • Repeat accuracy ± 1 mm
  • Up to 90% cost savings compared to traditional methods
  • Unlimited use during day and night, rain and bright sunshine – no line of sight requirements
  • Measurement of objects close to track

Modular system design

  • Measuring trolley consisting of precision sensors for gauge, superelevation and distance and ruggedized notebook
  • AMU 1030 (Amberg Measuring Unit) for unrivalled kinematic measurement precision
  • Two different control point measuring devices:
    • Total station (IMS 1000, fully automatic measurement)
    • Profiler 110 FX (IMS 3000)
  • Modular system upgrading possibilities

Global 3D topographic track survey

  • Measuring performance up to 4000 m/h, typically 2500 m/h
  • Absolute 3D control points given in global coordinate grid and used as transformation references
  • Distance between CP measurements up to 500 m
  • Fully compatible with other geodetic 3D survey data

Local 3D topographic track survey

  • Measuring performance up to 4000 m/h, typically 2500 m/h
  • Setup and survey of control points during initial track survey
  • Track data available in local 3D coordinate grid
  • Determination of local 3D coordinates for established control points
  • Results can be used for local track design and track works as well as monitoring purposes

Relative track geometry survey

  • Measuring performance up to 5000 m/h, typically 3500 m/h
  • Stationing plates as references
  • Measurement and calculation of track parameters horizontal versines (variable chord length), vertical versines (variable chord length), gauge, superelevation and twist
  • Presentation and analysis of track data with sophisticated
  • Track Geometry Record (TGR)
