AB Web  cracking  tendencies  were  evaluated  in rails similar to those
   having   unacceptable  behaviour  in  field.  Cracking  tendency  was
   determined through the use of two destructive measurement techniques,
   both  of  which  require  sawcuts along the neutral axis of the rail.
   These  tests  provide an assessment of the stress intensity available
   to  drive  web  cracks.  Both  of  these techniques yielded a similar
   ranking  of  cracking  tendency  over  a range of several samples. An
   ultrasonic-based  nondestructive  measurement technique was also used
   to  map out residual stress distributions in these rails. Many of the
   rails  evaluated  in this study exhibited stress intensities of about
   twice their ability to resist unstable fracture, in essence. Although
   the  sampling  was  limited,  a  simple  correlation was seen between
   maximum  compressive longitudinal stress in the webs of the rails and
   the average stress intensity calculated by the destructive methods.
