With railways, a break of gauge occurs where a line of one track gauge (the distance between the rails, or between the wheels of trains designed to run...

In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway...

A radius gauge, also known as a fillet gauge, is a tool used to measure the radius of an object. Radius gauges require a bright light behind the object...
