Question

Which is the newest tube line and which is the oldest?

Answer 1

The oldest part of the Underground network is the stretch from Praed Street (Paddington) to Farringdon via Baker St. and Kings Cross, which now forms part of the Circle Line. It opened in 1863 and was the first underground railway in the world.

The oldest deep level line was the City & South London Railway, running from Stockwell to KIng William Street. This now forms part of the Northern Line, particularly the Bank branch, and was opened in 1890.

The newest tube line is a little bit more complex.

The newest line to be built in its entirety is the Victoria Line, which was opened in stages between 1967 and 1971.

However, the newest line can be considered the Jubilee Line extension, from just south of Green Park to Stratford, which opened in late 1999. The north end of the line, from Stanmore to Baker Street, was once part of the Bakerloo Line, opened in the 1930s. The two branches, from Stanmore and what is now the existing Bakerloo Line, converged at Baker Street (the junction is still there and is used by engineering trains) and this was causing congestion so the decision was taken to open a 'new' line using the existing Stanmore branch tracks with the addition of an extension. Provisionally called the Fleet Line, this involved the building of new platforms at the existing Baker Street, Bond Street, Green Park and Strand stations (this was renamed Charing Cross), with plans for an extension to Lewisham, following the path of the subterranean Fleet river (hence the name). Stage 1 was completed and renamed the Jubilee Line, running from Stanmore to Charing Cross, opening in 1979.

Plans for the extension were put on hold, however, until the early 1990s when a new route was proposed and built, the aforementioned extension from Green Park to Stratford, opening in 1999.

Answer 2

The oldest tube line is the one from Paddington to Farringdon Street which opened in the mid-Victorian era.

The latest is the Underground connection to Heathrow Airport.

Answer 3

The Northern Line is the oldest 'tube' line in the London Underground, and therefore the oldest such Underground line in the world. There's a semantic difference between tube lines, and so called 'subsurface' lines, distinguished by the line's construction method. Tube lines, such as the Northern Line, are constructed by boring tunnels, whereas 'subsurface' lines (such as the older Hammersmith & City Line) are constructed by digging a trench, and covering it over.

It originally opened in 1870, consisting of a 410 metre long tunnel running under the Thames near Tower Bridge. Losing money hand over fist, the line closed three months after opening, and the tunnel was converted into a foot tunnel.
