TAT-1 was the first submarine transatlantic telephone cable system. It was laid between Kerrera, Oban, Scotland and Clarenville, Newfoundland. Two cables were laid between 1955 and 1956 with one cable for each direction. It was inaugurated on September 25, 1956. The cable was able to carry 35 simultaneous telephone calls. A 36th channel was used to carry up to 22 telegraph lines.

The Kingsway tramway subway is a cut-and-cover tunnel in central London, built by the London County Council, and the only one of its kind in Britain. The decision in 1898 to clear slum districts in the Holborn area provided an opportunity to use the new streets for a tramway connecting the lines in the north and south. Following the pattern of tramways in New York and Boston, it was decided to build this as an underground connection.
Aldwych is a closed station on the London Underground, located in the City of Westminster in Central London. It was opened in 1907 with the name Strand, after the street on which it is located. It was the terminus of the short Piccadilly line branch from Holborn that was a relic of the merger of two railway schemes. The station building is close to the Strand's junction with Surrey Street, near Aldwych. During its lifetime, the branch was the subject of a number of unrealised extension proposals that would have seen the tunnels through the station extended southwards, usually to Waterloo.

Anchor Exchange was an underground, hardened telephone exchange built in Birmingham, England. Construction commenced in 1953 under the guise of building an underground railway. It opened in September 1957 at a cost of £4 million. It was located nominally on Newhall Street. However its network of tunnels extended from at least the Jewellery Quarter to Southside.
Guardian Exchange was an underground telephone exchange built in Manchester from 1954 to 1957. It was built together with the Anchor exchange in Birmingham and the Kingsway exchange in London – all believed to provide hardened communications in the event of nuclear war; as well as linking the UK government in London to the US Government in Washington, D.C. by means of a secure and hardened transatlantic telephone cable making landfall near Oban and running through Glasgow, Manchester and Birmingham. Today, the underground site is used for telephone cabling. Constructed at a depth of below 35 metres (115 ft), the tunnels are about 2 metres (80 in) in diameter. The exchange cost around £4 million, part of which was funded by the United Kingdom's NATO partners.

High Holborn is a street in Holborn and Farringdon Without, Central London, which forms a part of the A40 route from London to Fishguard. It starts in the west at the eastern end of St Giles High Street and runs past the Kingsway and Southampton Row, becoming Holborn at its eastern junction with Gray's Inn Road. The western stretch, as far as Drury Lane, was formerly known as Broad Street. On High Holborn, traffic flows one-way westbound from its junction with Drake Street to its western end, and flows both ways for the remainder.
The London deep-level shelters are eight deep-level air-raid shelters that were built under London Underground stations during World War II.
A number of military citadels are known to have been constructed underground in central London, dating mostly from the Second World War and the Cold War. Unlike traditional above-ground citadels, these sites are primarily secure centres for defence coordination.
The Central London Railway (CLR), also known as the Twopenny Tube, was a deep-level, underground "tube" railway that opened in London in 1900. The CLR's tunnels and stations form the central section of the London Underground's Central line.
The A4200 is a major thoroughfare in central London. It runs between the A4 at Aldwych, to the A400 Hampstead Road/Camden High Street, at Mornington Crescent tube station, via Holborn, Bloomsbury, Euston and Somerstown.
The Central Government War Headquarters (CGWHQ) is a 35-acre (14 ha) complex built 120 feet (37 m) underground as the United Kingdom's emergency government war headquarters – the hub of the country's alternative seat of power outside London during a nuclear war or conflict with the Soviet Union. It is in Corsham, Wiltshire, in a former Bath stone quarry known as Spring Quarry, under the present-day MoD Corsham. In 1940, during the Second World War, the site was acquired by the Minister of Aircraft Production and used as an underground engine factory. The war headquarters was commissioned in 1955, after approval by Prime Minister Anthony Eden. However, it became outdated shortly after it was built, due to intercontinental ballistic missiles being able to target it, and the formulation of other plans. Nevertheless, the complex continued to have a role in war plans and remained in operation for 30 years.

The eastern extension of the building stands on the site of Doctors' Commons whose members had lower-courts say in ecclesiastical and admiralty matters.
The Great Northern, Piccadilly and Brompton Railway (GNP&BR), also known as the Piccadilly tube, was a railway company established in 1902 that constructed a deep-level underground "tube" railway in London, England. The GNP&BR was formed through a merger of two older companies, the Brompton and Piccadilly Circus Railway (B&PCR) and the Great Northern and Strand Railway (GN&SR). It also incorporated part of a tube route planned by a third company, the District Railway (DR). The combined company was a subsidiary of the Underground Electric Railways Company of London (UERL).
