Grade Crossing Rail Inspection: UT Challenges Explained
Grade Crossing Rail Inspection explains UT limits at road crossings, including hidden corrosion, restricted access and methods that support safer rail maintenance.
Relay Rail Inspection: UT Testing Before Rail Reuse in 2026
Relay Rail Inspection explained: learn how UT finds hidden defects, supports rail classification, and helps assess used rail for reuse.
Rail Grinding and Its Effect on Ultrasonic Inspection
Rail grinding removes about 0.006–0.008 in. per pass. How it changes UT coupling, clears shelling that masks defects, and fits 49 CFR 213.237 test intervals.
Rail Joint Inspection: How UT Detects Joint Bar Cracks
Rail joint inspection under 49 CFR 213.121 and 213.119: why rail flaw UT misses joint bar cracks, how joint-bar UT finds them, and CWR joint intervals.
Sperry Rail Car: How Ultrasonic Rail Testing Started in the USA
The Sperry rail car began induction rail testing in 1928. Ultrasonics followed from 1949, and FRA has required internal rail testing since 1971. Dated timeline.
Rail Inspection RFP Manual for Ultrasonic Testing
Rail inspection RFP clauses for ultrasonic testing: cite 49 CFR 213.237, 213.238, 213.241 and 213.113, set valid-search, verification and reporting terms.
