Vertical Split Head in Rail: Definition, Causes and Ultrasonic Detection
A vertical split head is a lengthwise split in the middle of the rail head, defined in 49 CFR 213.113. How it forms, how UT finds it and which action applies.
Head Checks in Rail: Causes, Progression, and When They Become Dangerous
Head checks in rail are gauge corner cracks 2–5 mm apart that can hide detail fractures from UT. Crack depths, 213.113(d)(7), 213.237(h) and grinding.
Rail Shelling and Spalling: Surface Defects That Lead to Internal Failures
Rail shelling and spalling are different head defects. Shells start below the gauge corner, mask ultrasonic tests and seed detail fractures. How to verify.
