Railcar Wheel Inspection AI
Inspect every wheel on every passing train for flat spots, shelling, spalling, cracks, and thin flanges.
Railcar Wheel Inspection AI for the Toughest Freight, Transit, and Passenger Rail Networks
Deploy Anywhere, Run Everywhere
Run railcar wheel inspection on wayside portals, shop pits, and handheld devices on the edge, on-prem, in your VPC, or via API.
One Platform, Full Adoption
Tools every rail mechanical team can adopt, from car inspectors to network operations, no separate ML team required.
Secure, Compliant, and Audit-Ready
Data stays safe with SOC 2 Type II compliance, encrypted data, HIPAA compliance, and an uptime SLA.

Inspect Every Wheel on Every Train, from the Wayside Portal to the Wheel Shop
Bring real-time intelligence to every wheel on the network with Roboflow Vision AI for railcar wheel inspection. Built for freight and passenger railroads where a single cracked wheel can derail a train, where flats pound the track and bearings, and where visual checks in the yard only reach the wheels an inspector can walk to.
Tread and flange condition:
- Detect wheel flats, built-up tread, shelling, and spalling on the tread with a model trained on your own wayside and shop images.
- Measure flange height and thickness from profile images and flag thin and high flanges.
- Find hollow tread and other profile wear that affects ride and steering.
Cracks and structural damage:
- Detect cracks in the rim, plate, and hub, and chipped or broken rims.
- Flag heat checking and discoloration that point to overheated wheels.
- Send the image and location of each finding for car inspector confirmation.
Car, axle, and trend:
- Read the car number and tie each finding to car, truck, axle, and side, next to railcar identification.
- Trend each wheel across passes to plan wheel changes before a finding becomes a bad order.
- Send findings to network operations and the shop so cars are set out at the right terminal.
Bring intelligence to every wheel today. Stop flats and cracked wheels from becoming derailments, track damage, and bad order cars.
Frequently asked questions
What is railcar wheel inspection with Vision AI?
Railcar wheel inspection with Vision AI uses wayside portals, shop pit cameras, or handheld devices and a trained computer vision model to find wheel flats, shelling, spalling, cracks, and flange wear on every wheel, tie each finding to the car and axle, and trend condition over passes. It is part of railcar and rolling stock inspection, alongside railway track inspection.
Can Vision AI inspect wheels on a train moving at track speed?
Yes. Wayside portals use high-speed cameras with short exposures and strobe or line lighting to capture sharp images of each wheel as the train passes, and a model trained on your own imagery finds tread damage, cracks, and flange wear in each frame. Axle counters and car number reads tie every image to its car, truck, and axle, so findings are ready for the mechanical team by the time the train clears the site.
Does railcar wheel inspection support FRA Part 215 and AAR rules?
Railcar wheel inspection supports the wheel condition requirements of FRA 49 CFR Part 215 (the US railroad freight car safety standards, including wheel defects) and AAR interchange rules (the Association of American Railroads rules for car condition and wheel defects in interchange), with image records for each finding.
Roboflow serves as the inspection engine, and your mechanical teams own the condemning limits, set-out decisions, and repairs.
Can it integrate with our wayside detectors and mechanical systems?
Yes. Roboflow sends findings, car and axle IDs, and images over REST or MQTT, or writes them to a database, so they join wayside detector data such as wheel impact load and hot box readings in the railroad's equipment health system, and create repair records in car repair billing and shop systems.
