Full scale train laser scanning & inspection

Trimble® TrainView®-LS is an automatic full scale train laser scanning inspection system that uses 3D data to inspect each car (wagon) in a train at mainline operational speeds.

Inspection of the outside of railcars, using 3D data, at mainline speeds

Full scale train laser scanning & inspection

Trimble TrainView-LS is an automatic full scale train laser scanning inspection system that uses 3D data to inspect each car (wagon) in a train at mainline operational speeds.

The system is designed to provide 3D shape of all externally visible components of a car. The data are then assigned to individual cars based on the AEI data so that car components can be analyzed as needed. The system uses multiple sensors and algorithms to pinpoint axle position, car beginning and car end positions and car components. Typical system applications are structural gauge and high-wide load detection, car load profile, load carry back detection and more.

Sophisticated image processing with alarms that alert to issues

Benefits to rail operators includes assisting with the visual inspection process and providing timely maintenance alerts for cases such as high-wide loads. The inspection process is fully automated and the date from TrainView-LS can be combined with the images from TrainView to create a composite 3D image data for improved car inspection results. This can be achieved within the Trimble TrainWatch™ train viewing software to perform a complete virtual train visual inspection.

TrainView-LS is also of relevance in the security industry where the detection of foreign objects on trains is becoming a critical issue for the rail transportation industry.

Dramatic savings in personnel time and costs, versus manual inspections

Full scale train laser scanning & inspection. Complete inspections quicker and minimize 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

TrainView-LS 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 TrainView-LS 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.

Inspections & Measurements

Trimble TrainView-LS system inspections and measurements include:

  • Car (wagon) structural gauge and profile.
  • High-wide detection.
  • Car (wagon) load profile.
  • Load carry back.
  • Car (wagon) orientation detection (leaning cars).
  • Side walls inspection.

Depending on the rolling stock types and requirements, the system’s imaging, inspection, and measurement outputs may require optimization or customization.

Many other measurements, inspections, and detections are possible, though may require the development of further Machine Vision Algorithms (MVAs) depending on requirements.
