Standards
On 22 September 1847, the RCH recommended that Greenwich Mean Time be adopted as the standard time for all railways in the United Kingdom.
The RCH went on to set technical standards for various items, such as goods wagons, to promote standardisation across the rail network. If a wagon was described as an RCH wagon, this meant it had been built to comply with RCH standards.
The RCH set technical standards for cable connections between coaches for the remote operation of systems; they were initially used only for control of train lighting. These cables were known as RCH jumpers, and in the 1970s a system for push-pull trains was developed which used the RCH cable, eliminating the need for a separate control cable to be fitted to intermediate coaches.
The RCH produced Railway Junction Diagrams (RJDs), which show the junctions where two or more railway companies met, and the distances between these junctions and nearby stations and junctions, in order to aid the calculation of mileage-based rates. Starting in 1871 it also issued what has been described as the "most superb series of railway maps ever produced in the United Kingdom."
The RCH had some similarities to the modern Association of Train Operating Companies, and in particular, its Rail Settlement Plan division.

Famous quotes containing the word standards:
“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)
“As long as our people quote English standards they dwarf their own proportions.”
—Ralph Waldo Emerson (1803–1882)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
