CORRail 2000

HaslerRail has been supplying speed indicators and data recording systems to the rail industry since 1887. Today, HaslerRail’s optical and contact-free CORRail 2000 speed sensor is unparalleled in terms of accuracy, precision and availability.

Features / Benefits

  • Speed sensing is unaffected by wheel slip / slide
  • Track-independent, dynamic measurement on railhead
  • Availability > 99.5%
  • Measurement range of 0.2 km/h to 600 km/h
  • Direction detection
  • Standstill detection (< 0.2 km/h)
  • No calibration is required as sensing is independent of wheel diameter
  • Robust design for mounting on bogie
  • Low maintenance and service costs
  • Splash guard protection extends cleaning interval to greater than six months

HaslerRail developed the optical and contact-free CORRail 2000 speed sensor to deliver track-bed independent direct measurement of a rail vehicle’s speed and direction. The technology behind the CORRail 2000 is known as Spatial Filtering Velocimetry and is neither affected by slip & slide effects nor by the wearing of the wheels as pulse generators are.

Using the railhead as reference makes the CORRail 2000 speed sensor outperforming microwave based sensors (= no calibration shift due to changing surfaces on the track-bed). By scanning the railhead’s microstructure with its high resolution the CORRail 2000 speed sensor’s accuracy and precision are unrivalled in its class.

The patented splash guard assures reliable results even under the harshest environmental conditions. The CORRail 2000 is proven in use: Availabilities of >99.5% are reached even the CORRail 2000 is being in operation for months.

The CORRail 2000 is designed to deliver an objective measurement of longitudinal dynamics for the following applications:

– Signaling Systems e.g. ETCS, ATO
– Propulsion Systems: True speed over ground for wheel slip slide control
– Measurement of braking distance: Navigation/Positioning
