Head checks - Rail defects


Figure 1: Head checks.

Defect name: Head checks
Record No.: 2588
Type of defect (Internal/Surface): Surface
Defect classification: Rail defects
Steel name: Steel
Steel composition in weight %: No data.
Note:   Definition - Head checks are the slight separations of metal on the gauge side of the rail head, normally found on the high side of curves.

Origin - Head checks are common in switch areas, due to the lateral force induced on the rail head from wheel displacement through turnouts.

Growth - Head checks can turn down and develop into a transverse separation.

Detection - Head checks can be detected by visual inspection.
