4.1 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.
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.
