I   recall that one argument for the use of grooved rail was that
on curves the opposite wheel to that creating the wear shown would
bear against the groove lip and prevent the 'grinding' wheel flange
cutting into the running rail.  The wear shown indicates that the lip
of the other rail did not function in this way.  Gauge incorrect or
the groove too wide?

Subject:[TramsDownUnder] CESLR rail wear

I was down at Central Chalmers at lunch time and noted significant
guage face wear on the curves both at Devonshire and Eddy Ave sides of
the stop.
Not only are the gauge faces chewed out over 5mm, but chips of loose
metal are collecting in the groove.
See -
This piece I picked up off the tracks just before the line turns under
the railway viaduct. It's over 20cm long. The multi-tool is calibrated
in mm on one side (and inches on the other). The wheels are not just
grinding the rail surface away, the are squeezing a sliver of metal
out.

Soon there will be a week-long shutdown so they can replace the rails
in these curves. So much for the consortium ensuring the
infrastructure and the cars chosen are compatible.
