Transverse defect from shelling
|
A transverse defect propagated from shelling. this defect originates below the rail surface usually at the gauge corner on high legs of curves and can mask a transverse defect that grows into the rail head. the origin of this defect is high stresses below the rail surface that grow from an imperfection in the steel, for example a minute inclusion.

Transverse defect from wheel burn, английский
A transverse defect propagated from a wheel burn. a slipping wheel heats the rail surface and may flow the metal. rapid cooling forms thermal cracks and wheel pounding starts horizontal separations. visual detection is usually not possible due to masking by the wheel burn.
