MiddlesexMiddlesex (ˈmɪdəlsɛks; abbreviation: Middx) is a historic county in southeast England. Its area is almost entirely within the wider urbanised area of London and mostly within the ceremonial county of Greater London, with small sections in neighbouring ceremonial counties. Three rivers provide most of the county's boundaries; the Thames in the south, the Lea to the east and the Colne to the west. A line of hills forms the northern boundary with Hertfordshire.
TunnelA tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel.
Euston railway stationEuston railway station ('juːstən ; also known as London Euston) is a central London railway terminus in the London Borough of Camden, managed by Network Rail. It is the southern terminus of the West Coast Main Line, the UK's busiest inter-city railway. Euston is the eleventh-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.
Train stationA train station, railway station, railroad station, or railway depot is a railway facility where trains stop to load or unload passengers, freight, or both. It generally consists of at least one platform, one track, and a station building providing such ancillary services as ticket sales, waiting rooms, and baggage/freight service. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements.
WatfordWatford (ˈwɒtfərd) is a town and borough in Hertfordshire, England, north-west of Central London, on the banks of the River Colne. Initially a small market town, the Grand Junction Canal encouraged the construction of paper-making mills, print works, and breweries. While industry has declined in Watford, its location near London and transport links have attracted several companies to site their headquarters in the town. Cassiobury Park is a public park that was once the manor estate of the Earls of Essex.
ThameslinkThameslink is a 24-hour main-line route in the British railway system, running from , , , and via central London to Sutton, , , Rainham, , and . The network opened as a through service in 1988, with severe overcrowding by 1998, carrying more than 28,000 passengers in the morning peak. All the services are currently operated by Govia Thameslink Railway. The Thameslink Programme was a major £5.5 billion scheme to increase capacity on the central London section by accommodating more frequent and longer trains, and providing additional routes and destinations.
City and South London RailwayThe City and South London Railway (C&SLR) was the first successful deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotives—an experimental technology at the time—was chosen instead. When opened in 1890, the line had six stations and ran for in a pair of tunnels between the City of London and Stockwell, passing under the River Thames.
