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:
“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”
—Rutherford Birchard Hayes (1822–1893)
“In full view of his television audience, he preached a new religion—or a new form of Christianity—based on faith in financial miracles and in a Heaven here on earth with a water slide and luxury hotels. It was a religion of celebrity and showmanship and fun, which made a mockery of all puritanical standards and all canons of good taste. Its standard was excess, and its doctrines were tolerance and freedom from accountability.”
—New Yorker (April 23, 1990)
