Inspect railway car axle and wheel assemblies, using measuring instruments.
What does a Railroad Wheels and Axle Inspector do?
Inspects railway car axle and wheel assemblies to determine conformance to Federal and American Railroad Association specifications, using measuring instruments: Verifies diameter of wheel and journal seats on axle, using calipers and micrometers. Measures space between wheels and from center of axle to each wheel, using needle-pointed space gauge, to verify conformance to specifications. Observes hydraulograph pressure-gauge indicator on wheel-pressing machine, as wheels are pressed onto axles, to ensure conformity to ton-pressure tolerances.
