machine gauge

Machine gauge refers to the width between the rails of a railway track, determining the distance across the wheels that run on the rails. It’s a standard measurement used to categorize different track types, affecting stability, speed, and the types of trains that can operate on them. Common gauges include standard gauge (1,435 mm or 4 ft 8 1/2 in), broad gauge, and narrow gauge. Proper gauge selection influences track construction, operational efficiency, and compatibility across railway systems. Essentially, gauge ensures that trains and tracks fit together correctly for safe and efficient movement.
