Precision Rail Feeler Gauge Ruler Rail Track Measuring Tools
A rail feeler gauge or gap ruler is a tool that is used to measure the distance between two rails. It is used to ensure that the rails are properly aligned and that there is not too much or too little space between them. Too much space between the rails can cause the train to derail, while too little space can cause the wheels to wear out prematurely.
Feeler gauges are typically made of steel or aluminum and have a series of graduated blades of different thicknesses. The blades are inserted between the rails and the thickness of the blade that fits snugly between the rails is the measurement of the gap.
Rail gap gauges are typically used by railroad workers to inspect tracks and ensure that they are safe for trains to operate on. They are also used by train manufacturers to ensure that the wheels of the trains are properly spaced.
To use a rail feeler gauge or gap ruler, follow these steps:
- Insert the blade of the gauge between the rails.
- Push the blade gently between the rails until it stops moving.
- Read the measurement on the gauge.
