A list of gauges of public railways and non-public railways, if of reasonable size. Some industrial railways unofficially carried passengers and goods. Everything that looks like a railway is considered to be one, and everything that looks like a tramway is considered to be one, no matter what the legal definition is/was. The information has been checked and has not been uncritically copied from similar lists. Not all railways using a specific gauge are listed and there is no distinction between operating and closed or regauged railways.

Supposedly original definitions are given in bold, their conversions in normal, and other in italics. Feet and inches are imperial unless otherwise stated.
