description: "Train a model on the agency own track images, taken from inspection vehicles or walking patrols, so it can mark frames that likely show broken or worn ties, missing or loose fasteners, ballast problems, vegetation on the track, or debris. Each mark carries the line, track and milepost or location from the image, so a qualified track inspector can review the frame and decide what follow-up is needed. The model only sorts images and points people to the ones worth a look; it never clears track for service or replaces the inspections that rules require, and all track work follows the existing safety and access rules."

# How can a railroad or transit agency use computer vision to review track inspection images?

Train a model on the agency own track images, taken from inspection vehicles or walking patrols, so it can mark frames that likely show broken or worn ties, missing or loose fasteners, ballast problems, vegetation on the track, or debris. Each mark carries the line, track and milepost or location from the image, so a qualified track inspector can review the frame and decide what follow-up is needed. The model only sorts images and points people to the ones worth a look; it never clears track for service or replaces the inspections that rules require, and all track work follows the existing safety and access rules.

## What this means in practice

- Collect past track images that qualified inspectors have already reviewed, across seasons and lighting
- Label the conditions the inspection program tracks, plus clean track sections for comparison
- Run new images through the model and list flagged frames by line, track and location
- Have a qualified track inspector review each flagged frame and record the decision
- Add reviewed frames back into training so the model fits the agency track types and territory

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
