Euston railway station is a major central London railway terminus 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.
Crossrail is a completed railway project centred on London. It provides a high-frequency hybrid commuter rail and rapid transit system, known as the Elizabeth line, that crosses the capital from suburbs on the west to east and connects two major railway lines terminating in London: the Great Western Main Line and the Great Eastern Main Line. The project was approved in 2007, and construction began in 2009 on the central section and connections to existing lines that became part of the route, which has been named the Elizabeth line in honour of Queen Elizabeth II who opened the line on 17 May 2022 during her Platinum Jubilee. The central section of the line between Paddington and Abbey Wood opened on 24 May 2022, with 12 trains per hour running in each direction through the core section in Central London.
Euston is a London Underground station. It directly connects with its National Rail railway station above it. The station is in Travelcard Zone 1.
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. Tunnels are excavated through hard rock, wet or dry soil, or sand, each of which requires specialized technology.
Old Oak Common (OOC) is a railway station under construction on the site of the Old Oak Common traction maintenance depot to the west of London in Old Oak Common, approximately 500 m (1,600 ft) south of Willesden Junction station. When built, it is expected to be one of the largest rail hubs in London, at about 800 m (2,600 ft) in length and 20 m (66 ft) below surface level.

High Speed 2 (HS2) is a high-speed railway which is under construction in England. The line will run between Handsacre, in southern Staffordshire, and London, with a spur to Birmingham. HS2 is to be Britain's second purpose-built high-speed railway after High Speed 1, which connects London to the Channel Tunnel. London and Birmingham will be served directly by new high speed track, and services to Glasgow, Liverpool and Manchester will use a mix of new high speed track and the existing West Coast Main Line. The majority of the project is planned to be completed by 2033.

Heathrow Hub railway station was a proposed interchange that would serve – mainly – a now disbanded potential alignment of High Speed 2 (HS2) services that would adjoin the expanded part of Heathrow Airport, England. It was a cornerstone part of an expansion plan put forward in 2008, by engineering firm Arup, to set up the UK's first high-speed rail network north-west of London.
The Lee Tunnel, also known as the Stratford to East Ham deep tunnel, is an overflow sewer in East London for storage and conveyance of foul sewage mixed with rainwater. It was built as part of the Thames Tideway Scheme and runs from Abbey Mills Pumping Station down to pumps and storage tanks at Jenkins Lane, Beckton Sewage Treatment Works. It is wholly under the London Borough of Newham.

The Tuen Mun - Chek Lap Kok TBM otherwise known as Qin Liangyu or more formally, the Mixshield S-880 was the world's largest tunnel boring machine launched in June 2015 by Herrenknecht in Germany. The TBM was used to drill a 5 km tunnel connecting Tuen Mun to the Hong Kong International Airport, part of the Tuen Mun–Chek Lap Kok Link project. The cost of the tunneling machine itself was around HK$ 18.2 billion
Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management. Tunnel construction is a subset of underground construction.
Stepney Green cavern is an underground junction which contains the junction where Crossrail divides into two branches: one to Shenfield and one to Abbey Wood. It is located below Stepney Green Park.
The history of High Speed 2 is the background to the planned construction of High Speed 2 (HS2), a new high-speed railway in Great Britain that was originally planned to connect London, Birmingham, Manchester, Leeds and other cities in the UK.
The Woodsmith Mine Tunnel is a 23-mile (37 km) long tunnel that will stretch between Woodsmith Mine at Sneatonthorpe near Whitby in North Yorkshire and the Wilton International complex on Teesside, England. The tunnel has been in development since 2016, but cutting of the tunnel bore did not start until April 2019, with an original projected completion date of 2021, now projected to 2030. By June 2024 tunnelling had advanced 18 miles (29 km), 78% complete.
The Colne Valley Viaduct is a bridge, under construction as of 2024, which will carry the High Speed 2 railway over the Colne Valley Regional Park and the Grand Union Canal, in Hillingdon, west London. When completed, its length of 3.4 kilometres (2.1 mi) and a weight of 116,000 tonnes will make it the largest railway bridge in the UK. It is one of the largest single civil engineering works of HS2 Phase 1.
Euston Square Gardens is a public garden on Euston Road in the London Borough of Camden.
The Chiltern Tunnel is a high-speed railway tunnel currently under construction in Buckinghamshire and Hertfordshire, England, and will upon completion carry the High Speed 2 (HS2) railway line under the Chiltern Hills. The twin-bore tunnels, which are 16.04 km long, will be the longest on the HS2 line. Each tunnel will also have additional 220 m (720 ft) entry and 135 m (443 ft) exit perforated concrete portals to reduce sudden changes in air pressure and subsequent noise.
The Northolt Tunnel is a high-speed railway tunnel currently under construction in Greater London, England, and will upon completion carry the High Speed 2 (HS2) railway line under the West London suburbs. The twin-bore tunnels will run for 8.4 miles (13.5 km) between Old Oak Common and Ruislip. As of March 2024, the first tunnel boring machine has completed 50% of its bore length.
