RCH meaning in Regional ?

The Railway Clearing House (RCH) was an organisation set up to manage the allocation of revenue collected by pre-grouping railway companies for the conveyance of passengers and goods over the lines (or using the rolling stock) of other companies. It went on to become the major regulatory body overseeing the day-to-day running of railways in Great Britain and setting common standards for railway companies, which ensured their safety and interoperability. The RCH also produced fare structures governing many aspects of rail transport at a national level and set limits on price increases for passenger travel.
