Measuring squats and studs

Posted by RailMeasurement on 20 June 2011

In June 2011, Dr Grassie presented a paper at the International Heavy Haul Conference in Calgary on so-called “squat” and “stud” type rail defects.  A PDF of the presentation can be found here.  Page 17 of the presentation shows measurements of the irregularities presented by “stud” defects on both rails.  Although the MSRCA was designed to measure corrugation, we have submitted a proposal to identify the location and quantify the severity of discrete irregularities such as squats and studs, which are prevalent in some locations on some types of track.  Two papers on these defects by Dr Grassie and his co-authors have been accepted for publication by the Institution of Mechanical Engineers and should appear early in 2012.
