transverse defect A single isolated transverse internal defect that occurs within the head of rail. The remaining rail length between adjacent welds should be checked ultrasonically for othertransverse defects. If these are present then the defect should be treated as a multiple transverse defect (TM). See “Multiple transverse defect”.The origin of this defect is an imperfection in the steel, eg. a shatter crack, minute inclusion, or an internal longitudinal seam or segregation. Impact of the wheels and bending stresses start the growth of a transverse separation around the imperfection. Visual detection is only possible after the defect has reached the surface. Rail breakage almost always occurs before the defect becomes visible.


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

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.
