United Kingdom
The United Kingdom brings together England, Scotland, Wales and Northern Ireland: the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands around them, off the north-western coast of continental Europe. Its only land border is with the Republic of Ireland; everywhere else it meets the Atlantic, the North Sea, the English Channel and the Celtic and Irish Seas. More than 69 million people live here. London is the capital of the UK and of England, and Edinburgh, Cardiff and Belfast are the capitals of Scotland, Wales and Northern Ireland.
Britain built the world's first railway system — the first public railway worked by locomotives opened in 1825 — and its network is still the fifth most used in the world. Network Rail looks after most of the track, while the trains belong to a set of operators, from LNER and Avanti West Coast on the main lines to Northern and ScotRail in the regions. Tickets are sold through one National Rail system, so a single fare can carry you across several operators' trains. The Channel Tunnel links the network to continental Europe, and many private railways, some of them narrow gauge, run short lines mainly for visitors.

What are Britain's best scenic railway journeys?
Scotland owns the top of the list. The West Highland Line from Glasgow to Fort William and Mallaig was voted the world's finest rail journey by Wanderlust readers; the Kyle Line crosses the Highlands to a pier facing Skye; and the steam-hauled Jacobite covers the Glenfinnan Viaduct leg in summer. England and Wales answer with the Settle–Carlisle line and the Welsh narrow-gauge railways.
Is Britain easy to explore by train?
Yes — the railway was born here, and the National Rail network still links the cities in hours, with London as the main hub. One national ticketing system covers every operator, so a single booking can take you from Cornwall to the Highlands. ScotRail and Transport for Wales carry you out into the scenic mountains of the north and west.
How do British train tickets work?
Fares can be confusing. "Advance" tickets, booked ahead for a specific train, are the cheapest; Off-Peak and Anytime tickets are flexible but dearer, and clever "split ticketing" can save money on longer trips. Overseas visitors covering lots of ground can buy a BritRail pass. Sleeper berths on the Caledonian Sleeper are booked separately with the operator, and sell out early for summer.
When is the best time to ride Britain's scenic railways?
May to September brings the best weather, the longest daylight and the fullest timetables — including the summer-only steam runs. Spring and autumn are quieter and often just as lovely, while winter turns the Highland lines into something wilder: shorter days, snow on the moors, and the overnight sleeper arriving into a white Fort William.
