Rail corrugation: advances in measurement,

2005-3-1  This provides an objective means of assessing the “quality” of ground rail, and proposes limits on residual irregularities that may remain on such a rail. Although grinding contractors have probably been grinding rail routinely to these limits for some time, extremely accurate measuring equipment is now available to demonstrate reliably that irregularities of only a few microns amplitude remain throughout a grinding

A Measured Approach to Improvements in Rail

2013-10-13  Among the areas that UP is exploring is non-destructive measurement of the depth of cracks on the rail surface. An accurate measurement of crack depth would help grinding supervisors to minimize metal removal and maximize grinding speed. UP is also looking for a way to quantify rail life extension due to grinding.
