Central London Railway

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 railway company was established in 1889, funding for construction was obtained in 1895 through a syndicate of financiers and work took place from 1896 to 1900. When opened, the CLR served 13 stations and ran completely underground in a pair of tunnels for 9.14 kilometres (5.68 mi) between its western terminus at Shepherd's Bush and its eastern terminus at the Bank of England, with a depot and power station to the north of the western terminus. After a rejected proposal to turn the line into a loop, it was extended at the western end to Wood Lane in 1908 and at the eastern end to Liverpool Street station in 1912. In 1920, it was extended along a Great Western Railway line to Ealing to serve a total distance of 17.57 kilometres (10.92 mi).

After initially making good returns for investors, the CLR suffered a decline in passenger numbers due to increased competition from other underground railway lines and new motorised buses. In 1913, it was taken over by the Underground Electric Railways Company of London (UERL), operator of the majority of London's underground railways. In 1933 the CLR was taken into public ownership along with the UERL.

In November 1889, the CLR published a notice of a private bill that would be presented to Parliament for the 1890 parliamentary session. The bill proposed an underground electric railway running from the junction of Queen's Road (now Queensway) and Bayswater Road in Bayswater to King William Street in the City of London with a connection to the then-under construction, City and South London Railway (C&SLR) at Arthur Street West. The CLR was to run in a pair of tunnels under Bayswater Road, Oxford Street, New Oxford Street, High Holborn, Holborn, Holborn Viaduct, Newgate Street, Cheapside, and Poultry. Stations were planned at Queen's Road, Stanhope Terrace, Marble Arch, Oxford Circus, Tottenham Court Road, Southampton Row, Holborn Circus, St. Martin's Le Grand and King William Street.
