Maintenance Standards
Infrastructure owners specify permitted variances for actual gauge, and the required interventions when non-compliant gauge is detected. For example, the Federal Railroad Administration in the USA specifies that the actual gauge of track that is rated for a maximum of 60 mph (96.6 km/h) must be between 4 ft 8 in (1,422mm) and 4 ft 9½ in (1,460mm).
