AI Wheel Integrity System
Norfolk Southern's AI wheel inspection prompted a recall and investigation that confirmed 7 defects
Problem
Wheel cracks could develop into serious mechanical failures. Some subtle defects were difficult for people to identify consistently.
Approach
Norfolk Southern deployed a dedicated wheel imaging system at Burns Harbor, Indiana. Its internal AI team developed the detection algorithms, with integration support from Georgia Tech Research Institute. Railroad teams confirmed detected defects and removed an affected car from service.
Results
Takeaway
The dedicated system inspected wheels from targeted angles. A detected manufacturing flaw led to a broader investigation beyond the original wheel.
