title: "How to check railcars at a yard with computer vision"
description: "Cameras beside the track at the gate or the plant spur take photos of each car as it rolls past. A model trained on the site own images reads the car number from the side, logs the time and the order of cars, and marks likely visible issues such as open or damaged doors, open hatches or loose covers, leaks or stains on the outside, missing placards and debris on the car. The car list goes to the yard team so they can match it against the expected cars and plan unloading, and each flag keeps its photo for the inbound inspection. Aim cameras at the cars, and blur any person who appears. Yard staff review the list and the flags and decide what to unload, hold or report. The model does not replace the required mechanical and safety inspections, placard rules or the railroad records, and people make every safety and acceptance call."

# How can a plant, terminal or short line use computer vision to log railcars and spot visible issues as they arrive?
Cameras beside the track at the gate or the plant spur take photos of each car as it rolls past. A model trained on the site own images reads the car number from the side, logs the time and the order of cars, and marks likely visible issues such as open or damaged doors, open hatches or loose covers, leaks or stains on the outside, missing placards and debris on the car. The car list goes to the yard team so they can match it against the expected cars and plan unloading, and each flag keeps its photo for the inbound inspection. Aim cameras at the cars, and blur any person who appears. Yard staff review the list and the flags and decide what to unload, hold or report. The model does not replace the required mechanical and safety inspections, placard rules or the railroad records, and people make every safety and acceptance call.
## What this means in practice
- Start with one gate or one spur.
- Label photos from your own cars for doors, hatches, leaks and placards.
- Match the car list against the expected cars each day.
- Send flags to the inbound inspector with the car number and photo.
- Keep required inspections and placard rules in place.
