Today, Britain's railways having been privatised, InterCity trains in the UK are operated by many different train companies including Abellio Greater Anglia, Avanti West Coast, CrossCountry, Great Western Railway, London North Eastern Railway, East Midlands Railway, Hull Trains, Scotrail and Grand Central. Most of these companies operate their services from one of the many London termini, with CrossCountry being the exception, running from Cornwall to Scotland. If travelling via London it is often necessary to change stations: a journey from Norwich to Cardiff would require a transfer from London Liverpool Street to London Paddington station via the London Underground.
