Rail Turnout Defect Detection AI for the Toughest Yards, Interlockings, and Mainline Switches

  • Deploy Anywhere, Run Everywhere

    Run turnout defect detection on hi-rail truck cameras, fixed cameras at switches, yard gantries, drones, the edge, on-prem, in your VPC, or via API.

  • One Platform, Full Adoption

    Tools every track and signal team can adopt, from track inspectors and roadmasters to signal maintainers, 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, with inspection records that support FRA Track Safety Standards (49 CFR Part 213).

  • Switch Point Gaps & Fit
  • Chipped & Worn Switch Points
  • Frog Point & Tread Wear
  • Guard Rail Condition & Flangeway Obstructions
  • Loose & Missing Bolts and Fasteners
  • Obstructions, Snow & Ice in Switches
“Achieving positive results using AI in a lab environment is easy, but the real challenge comes when scaling the solution across a network like ours without disrupting day-to-day operations. Our partnership with Roboflow is allowing us to do just that.”

Inspect Every Turnout, from the Switch Points to the Frog

Add a continuous inspection layer to every turnout with Roboflow vision AI for rail turnout defects. Built for yards, interlockings, and mainline switches, where a gapped switch point, a chipped point, or a worn frog can lead to a split switch or a derailment, and where FRA Part 213 sets specific requirements for switches, frogs, and guard rails.

Switch points and stock rails:

  • Detect gaps between the switch point and the stock rail in each closed position, so a point that is not fitting its stock rail is flagged before the next train.
  • Find chipped, broken, and worn switch points and the metal flow that keeps a point from closing, the conditions FRA requires to be repaired or replaced.
  • Check heel blocks, heel bolts, switch rods, and rail braces for loose, cracked, or missing parts, and confirm stock rails are seated in their switch plates.

Frogs, guard rails, and flangeways:

  • Spot chipped or broken frog points, tread wear, and cracks in frog castings, and trend wear by frog so replacement is planned around track time.
  • Inspect guard rails and wing rails for loose bolts, missing clips, and damage, with the same approach as railway track inspection.
  • Flag ballast, debris, snow, and ice in flangeways and between the switch points, since FRA requires every switch, frog, and guard rail to be kept free of obstructions.

Fasteners, ties, and the switch stand:

  • Grade turnout ties and count missing or loose spikes, plates, and bolts through the turnout, where FRA calls for more ties per segment than on plain track.
  • Check that the switch stand, connecting rod, and switch position indicator are in place, and that the indicator is clearly visible.
  • Send findings to track supervisors as work orders tied to milepost and switch number, and trend wear by turnout to plan repairs, as part of predictive maintenance.

Bring intelligence to every turnout today. Catch a gapped point, a chipped frog, or a packed flangeway before it becomes a slow order or a derailment.

Frequently asked questions

What is rail turnout defect detection with Vision AI?

Rail turnout defect detection with Vision AI uses cameras on hi-rail trucks, track inspection vehicles, drones, and fixed mounts at switches with a trained computer vision model (opens in a new tab) to find defects in switch points, stock rails, heel assemblies, frogs, guard rails, and turnout fasteners, and to flag obstructions in flangeways. Models train on images of your own turnouts, and every finding is tied to a switch number and milepost. It works alongside railway track inspection and railcar inspection on the same platform.

Why inspect turnouts continuously?

Turnouts have more moving parts and wear surfaces than plain track, and FRA Part 213 sets specific requirements for them: switch points must fit their stock rails, unusually chipped or worn points must be repaired or replaced, a frog with a badly worn point or tread is limited to 10 mph, and every switch, frog, and guard rail must be kept free of obstructions. FRA also requires CWR joints in switches and turnouts to be inspected on foot at least monthly. Cameras add a check between those inspections, with an image for every finding.

Does it work alongside walking inspections and track geometry cars?

Yes. Walking inspections and geometry cars measure gage, guard check gage, and frog wear with tools and sensors. Cameras add a visual check of every turnout between those inspections, with an image behind every finding, so inspectors spend their time at the switches that need it.

Roboflow serves as the inspection engine, and your track and signal teams own the inspection criteria, alert thresholds, and repair decisions.

Can it integrate with our track asset management and maintenance systems?

Yes. Roboflow writes findings to a PLC tag over OPC UA, Modbus TCP, or MQTT, and sends results and images over REST (opens in a new tab) or to a database for asset management platforms such as SAP and IBM Maximo and GIS systems keyed to milepost and switch number, where they become work orders and alerts. Models run on edge hardware on the truck, on a server at the yard, or in your VPC.
