Standard Gauge Railway
About Standard Gauge Railway
The track gauge of four feet eight and a half inches, 1435 millimeters, popularized by George Stephenson and required for new passenger lines in Great Britain by the Gauge Act of 1846. Well over half of the world's railway lines use it, including nearly all high speed lines from the Shinkansen to Europe, a prime example of a standard too entrenched to change.
