Question: what is the difference between broad gauge and standard gauge?
Answer: Broad gauge is also called wide gauge or large line. The distance between the two tracks in these railway gauges is 1676 mm (5 ft 6 in). It would not be wrong to say that any gauge, wider than standard gauge or 1,435 mm (4 ft 8½ inches), is called broad gauge. ... Broad gauge railway is also used on ports for crane etc.
