Mondo Knows Facts

Standard railway tracks measure four feet eight and a half inches wide

Traditional wagon wheel spacing established global railway track gauge dimensions

Approximately sixty per cent of the world's railway lines use the standard gauge width of 1,435 millimetres. Pioneer engineer George Stephenson adopted this dimension for early British coal tramways based on traditional horse wagon wheel spacing. The specification spread globally across Europe, North America, and international transit networks.
