Track gauge or rail gauge (also known as track gage in the United States) is the distance between the inner sides (gauge sides) of the heads of the two load bearing rails that make up a single railway line. Each county uses different gauges for different types of trains. However, the 4 ft 8½ in gauge was the basis of 60% of the world's railways.

Famous quotes containing the word track:
“It is remarkable how easily and insensibly we fall into a particular route, and make a beaten track for ourselves. I had not lived there a week before my feet wore a path from my door to the pond-side; and though it is five or six years since I trod it, it is still quite distinct. It is true, I fear, that others may have fallen into it, and so helped to keep it open.”
—Henry David Thoreau (1817–1862)
