Measuring Headwear

Headwear is the deterioration of the top of the profile as a result of the friction between

moving wheel and the rail.

To measure headwear, again ensure the gauge is fully in contact with the rail, please push

the knob or the sliding mechanism directly and not the body of the gauge as this can

cause the gauge to lockup, then the vertical headwear slide can be adjusted until the

measuring pin is touching the top of the rail. The headwear scale on the side of the gauge

will display the measurement for that position.

Headwear is also displayed in mm worn since the rail was new.
