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).

Famous quotes containing the words maintenance and/or standards:
“It is an injustice that an old, broken, half-dead father should enjoy alone, in a corner of his hearth, possessions that would suffice for the advancement and maintenance of many children.”
—Michel de Montaigne (1533–1592)
“The things a man has to have are hope and confidence in himself against odds, and sometimes he needs somebody, his pal or his mother or his wife or God, to give him that confidence. He’s got to have some inner standards worth fighting for or there won’t be any way to bring him into conflict. And he must be ready to choose death before dishonor without making too much song and dance about it. That’s all there is to it.”
—Clark Gable (1901–1960)
