Measuring Sidewear
The sidewear measurement is the amount of wear caused on the side of the profile by the
contact of the wheel on the running rail.
To measure the sidewear, ensure the gauge is fully in contact with the rail as shown
previously then the horizontal measuring slide can be adjusted as shown in figure 4.
Once the lower corner of the measuring pin is in contact with the worn edge of the profile,
the measurement can be taken from the sidewear scale on the top of the gauge, as shown
in figures 5 and 6. The sidewear measurement is given as mm worn since the rail was
new.
