London station group in the context of "St Pancras Station"

Charing Cross railway station (also known as London Charing Cross) is a central London railway terminus between the Strand and Hungerford Bridge in the City of Westminster. It is the terminus of the Southeastern Main Lines to Dover via Ashford and Hastings via Tunbridge Wells. All trains are operated by Southeastern, which provides the majority of commuter and regional services to south-east London and Kent. It is connected to Charing Cross Underground station and is near to Embankment Underground station and Embankment Pier.

The station was originally opened by the South Eastern Railway in 1864. It takes its name from its proximity to the road junction Charing Cross, the notional "centre of London" from which distances from the city are measured. During the 19th century the station became the main London terminus for continental traffic via boat trains, and served several prestigious international services. It was badly damaged by a roof collapse in 1905 and extensively rebuilt, subsequently becoming an important meeting point for military and government traffic during World War I. By this time, Charing Cross station was seen as out of date by some politicians and proposals were made to replace Hungerford Bridge with a road bridge or road/rail combination, with the station moving to the south bank of the River Thames in the case of a road-only replacement. The station was bombed several times during World War II, and was rebuilt afterwards, re-opening in 1951. In the late 1980s, the station complex was redesigned by Terry Farrell and rebuilt to accommodate a modern office block, now known as Embankment Place.

The Circle line is a spiral-shaped London Underground line, running from Hammersmith in the west to Edgware Road and then looping around central London back to Edgware Road. The railway is below ground in the central section and on the loop east of Paddington. Unlike London's deep-level lines, the Circle line tunnels are just below the surface and are of similar size to those on British main lines. Printed in yellow on the Tube map, the 17-mile (27 km) line serves 36 stations, including most of London's main line termini. Almost all of the route, and all the stations, are shared with one or more of the three other sub-surface lines, namely the District, Hammersmith & City and Metropolitan lines. On the Circle and Hammersmith & City lines combined, over 141 million passenger journeys were recorded in 2019.

The first section became operational in 1863 when the Metropolitan Railway opened the world's first underground line between Paddington and Farringdon with wooden carriages and steam locomotives. The same year a select committee report recommended an "inner circle" of lines connecting the London railway termini, and the Metropolitan District Railway (commonly known as the District Railway) was formed to build the southern portion of the line.

King's Cross railway station, also known as London King's Cross, is a passenger railway terminus in the London Borough of Camden, on the edge of Central London. It is in the London station group, one of the busiest stations in the United Kingdom and the southern terminus of the East Coast Main Line to Yorkshire and the Humber, North East England and Scotland. Adjacent to King's Cross station is St Pancras International, the London terminus for Eurostar services to continental Europe. Beneath both main line stations is King's Cross St Pancras tube station on the London Underground; combined, they form one of the country's largest and busiest transport hubs.

The station was opened in King's Cross in 1852 by the Great Northern Railway on the northern edge of Central London to accommodate the East Coast Main Line. It quickly grew to cater to suburban lines and was expanded several times in the 19th century. As part of the Big Four grouping in 1923, it came under the ownership of the London and North Eastern Railway, who introduced famous services such as the Flying Scotsman and locomotives such as Mallard. The station complex was redeveloped in the 1970s, simplifying the layout and providing electric suburban services, and it became a major terminus for the high-speed InterCity 125. As of 2018, long-distance trains from King's Cross are run by London North Eastern Railway to Edinburgh Waverley, Leeds and Newcastle; other long-distance operators include Hull Trains and Grand Central. In addition, Great Northern runs suburban commuter trains around North London, Hertfordshire, Cambridgeshire and Norfolk.

Stratford is a major multi-level interchange station serving the town of Stratford and the mixed-use development known as Stratford City, in the London Borough of Newham, East London for London Underground, London Overground, Docklands Light Railway (DLR) and Elizabeth line services. National Rail services also operate on the West Anglia Main Line and the Great Eastern Main Line, 4 miles 3 chains (6.5 km) from Liverpool Street.

It is the seventh busiest railway station in Britain, the second busiest station in London outside the London station group, and is the busiest station on the London Underground network outside London fare zone 1.

St Pancras railway station (/ˈpæŋkrəs/), officially known since 2007 as London St Pancras International, is a major central London railway terminus on Euston Road in the London Borough of Camden. It is the terminus for Eurostar services from Belgium, France and the Netherlands to London. It provides East Midlands Railway services to Leicester, Corby, Derby, Sheffield and Nottingham on the Midland Main Line, Southeastern high-speed trains to Kent via Ebbsfleet International and Ashford International, and Thameslink cross-London services to Bedford, Cambridge, Peterborough, Brighton, Horsham and Gatwick Airport. It stands between the British Library, the Regent's Canal and London King's Cross railway station. Beneath both main line stations is King's Cross St Pancras tube station on the London Underground; combined, they form one of the country's largest and busiest transport hubs.

The station was constructed by the Midland Railway (MR), to connect its extensive rail network, across the Midlands and North of England, to a dedicated line into London. After rail traffic problems following the 1862 International Exhibition, the MR decided to build a connection from Bedford to London with its own terminus. The station was designed by William Henry Barlow, with wrought iron pillars supporting a single-span roof. At 689 feet (210 m) by 240 feet (73.2 m) wide, and 100 feet (30.5 m) high, it was then the largest enclosed space in the world. Following the station's opening 1 October 1868, the MR built the Midland Grand Hotel on the station's façade. George Gilbert Scott won the competition to design it, with an ornate Gothic red-brick scheme. St Pancras has been widely praised for its architecture and is now a Grade I listed building.

Euston railway station (/ˈjuːstən/ YOO-stən; or London Euston) is a major central London railway terminus and connected London Underground station managed by Network Rail in the London Borough of Camden. It is the southern terminus of the West Coast Main Line, the UK's busiest inter-city railway. Euston is the tenth-busiest station in Britain and the country's busiest inter-city passenger terminal, being the gateway from London to the West Midlands, North West England, North Wales and Scotland.

Intercity express passenger services to the major cities of Birmingham, Manchester, Liverpool, Glasgow and Edinburgh, and through services to Holyhead for connecting ferries to Dublin are operated by Avanti West Coast. Overnight sleeper services to Scotland are provided by the Caledonian Sleeper. London Northwestern Railway provide commuter and regional services to the West Midlands, whilst the Lioness line of the London Overground provides local suburban services in the London area via the Watford DC Line which runs parallel to the West Coast Main Line as far as Watford Junction. Euston tube station is connected to the main concourse and Euston Square tube station is nearby. King's Cross and St Pancras railway stations are about 1⁄2 mile (800 metres) east along Euston Road.

Fare zone 1 is the central zone of Transport for London's zonal fare system used by the London Underground, London Overground, Docklands Light Railway and National Rail. For most tickets, travel through Zone 1 is more expensive than journeys of similar length not crossing this zone. The zone contains all the central London districts, most of the major tourist attractions, the major rail terminals, the City of London, and the West End. It is about 6 miles (10 km) from west to east and 4 miles (6 km) from north to south, approximately 17 square miles (45 km).
