Inter-city rail in the United Kingdom

In Great Britain, there are inter-city trains to numerous parts of the country. Most of these trains are high speed, and some operate into France and Belgium.

After the sectorisation of British Rail, inter-city trains were operated by InterCity. InterCity ran trains from London to Devon, Cornwall, Bristol, South Wales, Cheltenham, the Cotswolds, Oxford, the West Midlands, the East Midlands, North Wales, North West England, Yorkshire and the Humber, North East England, Scotland, East Anglia, and London Gatwick Airport. There were also numerous cross-country services, which were inter-city services that traversed several regions and usually avoided Greater London.

The UK's longest direct rail service is operated by CrossCountry from Aberdeen to Penzance, and takes 13 hours 23 minutes to complete.
