Rail gauge

Rail gauge is the distance between two rails of a railroad. Sixty percent of the world's railways use 1435 mm (4 ft 8½ inch) gauge, which is known as standard gauge or international gauge. Rail gauges larger than standard gauge are called broad gauge, and rail gauges smaller than standard are called narrow gauge. A dual gauge railway has three or four rails positioned so that trains of two different gauges can use it. A place where different gauges meet is called a break of gauge.
