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.
