Standard Gauge for railways with 1435mm RailGauge track gauge

The standard gauge (also Stephenson gauge after George Stephenson, International gauge or normal gauge) is a widely used railway track gauge. Approximately 60% of lines in the world are this gauge (see the list of countries that use the standard gauge). Except for Russia, Finland, Portugal and some upgraded lines in Spain, all high-speed lines are this gauge.

The distance between the inside edges of the rails is usually called 1,435 mm but in the United States, Canada and Britain it is still called 4 ft 8 1⁄2 in.

Standard gauge was originally called “narrow gauge” in contrast to Brunel’s broad gauge. When smaller gauges appeared, it was renamed “standard gauge”.[citation needed]

It’s also called “international gauge”, “UIC gauge”, or “UIC track gauge”

It’s called European gauge in the EU, as well as in Russia.

It’s called “uniform gauge” in Queensland.
