The re-profiling of the railway wheels is a corrective maintenance of railway wheels and are constantly being implemented, trained personnel from the Railway Company of Chile (EFE), with updates for rolling stock in different seasons .
This review of the wheels is needed to determine whether the profile of rolling wheels is within the parameters required by railway standards for the movement of trains, which are:
- Height of the tab.
- thickness of the tab.
- Distance between the inner faces of the wheel (DCI)
- Distance between the active faces of the wheel (DCA)
These parameters determine the degree of wheel wear.
In this sense, it is necessary to know the status of the wheel profiles of rail vehicles are in use on the tracks, which are known for different devices and methods for evaluating the crane rails.

GAUGE WHEEL: (H-697): Element used to measure the width of the wheel.
GAUGE H-696 A: determines:
- Tab (wear profile)
- Width of the tire (wear)
- grounding.
- Thickness of the rim.
MEASURING BRAKE O "RACE" CAR OR LOCOMOTIVES: The brake cylinder has an internal Stem, which is the element that determines the "race" of the brake and the same reaction time. Also, by law, must comply with a measure that varies between 6 and 8 inches, to provide an effective service.
