Wayside Brake Disc Profile Measurement System

The Trimble® BrakeView®-Disc automatic wayside brake disc inspection system operates on passing trains at mainline operational speeds. It is a machine vision system which uses a high-speed digital imaging system to acquire images of every brake disc for inspection and measurement.

The system is fully automated and can operate in extreme conditions—indoors and out. BrakeView-Disc is installed on a steel tie (sleeper) provided by Trimble. Cameras and illumination systems are installed in sealed enclosures installed on the system tie.

  • Disc profile measurement
  • Disc thickness for up to 4 discs per axle
  • Alarm on disc thickness levels
  • Alarms on unequal wear of discs
  • Visual image of the disc and surrounding area

Dramatic time and cost savings, versus manual inspections

Automate and complete brake wear profile, detection, cracks and breakage, retainer key presence, and height inspections quicker, minimizing time taken, costs, and issues that disrupt service.

Rolling stock stays in service for longer

With accurate measurements at mainline operational speeds there is minimal disruption to rolling stock schedules.

Limits risk to personnel, works 24/7, even in tough environments

BrakeView works in even the toughest environments and at night so field workers are not in unpleasant or unsafe working conditions thereby reducing the risk to their safety.

Digital accurate records, with automated alerts of issues

Providing digital records that are usable across operations and maintenance BrakeView reduces manual and paper-based workflows saving time and money. Critical issues are flagged and reported automatically so that corrective actions can be taken with less impact on service.

Easy to install system minimizes disruption and cost

BrakeView requires no track structure modification for ease of installation.
