DOES MISSING BALLAST RESULT IN DEVELOPMENT OF TRACK GEOMETRY DEFECTS?

The results of the study show that increasing volumes of missing ballast results in increases in the occurrence of track geometry defects and, in particular, the ballast-related track geometry defects, in those segments that have the missing ballast. This is consistent with basic industry practices...

Summary:The results of the study show that increasing volumes of missing ballast results in increases in the occurrence of track geometry defects and, in particular, the ballast-related track geometry defects, in those segments that have the missing ballast. This is consistent with basic industry practices and guidelines, which show a relationship between missing shoulder and/or crib ballast and reduced track strength.
