Similar to the New York Subway or the Paris Metro, the London Underground is London's series of (largely) underground trains that run a regular service throughout the city. Since the trains underground run through a series of tunnels, many people (Londoners and visitors alike!) refer to it as the tube.
Around 55% of the London Underground is actually above the ground. On the columns at Temple station, there are small temple-shaped emblems at the bases.
Bakerloo, Central, Jubilee, Northern, Piccadilly, Victoria and Waterloo & City lines. These are all something called a “Deep Level” or “Deep Tube” line. This means they're circular tunnels bored deep underground.
The Victoria line is a London Underground line that runs between Brixton in south London and Walthamstow Central in the north-east, via the West End. It is printed in light blue on the Tube map and is one of the only two lines on the network to run completely underground, the other being the Waterloo & City line.
However, when we asked Londoners on Facebook to nominate the Tube station that confused them the most, there was one that kept coming to the surface. Yes, you've guessed it, it's the Bank and Monument station interchange folks! According to you it's about as easy to navigate as a labyrinth...
About half of the underground lines, in terms of length, are actually on the surface when out of the central area. It is easier and safer to dig at depth in London because of the nature of the soil and to avoid other infrastructure and the Thames.
All London Underground trains are currently either operated manually (when a train driver controls starting and stopping, the operation of doors and handling of emergencies) or in semi-automatic mode (when starting and stopping is automated, but a driver operates the doors and drives the train if needed).
The Central line is a London Underground line that runs through central London, from Epping, Essex, in the north-east to Ealing Broadway and West Ruislip in west London. Printed in red on the Tube map, the line serves 49 stations over 46 miles (74 km), making it the longest line on the Underground.
The Metropolitan line is the oldest underground railway in the world. The Metropolitan Railway opened in January 1863 and was an immediate success, though its construction took nearly two years and caused huge disruption in the streets.
The New York Subway has more stations than the London Underground. Both systems have almost the same route miles. The New York Subway has more track miles because many routes have four tracks rather than the London Underground's two tracks.
The Waterloo & City and the Jubilee were the coolest lines, while the Metropolitan and Hammersmith & City attracted fewest complaints. TfL said air-conditioned trains were in use on 40 per cent of the Underground network. New trains due to be introduced on the Piccadilly line from 2025 will also have air conditioning.
THE world's deepest metro system is the Pyongyang Metro in North Korea which is 110 meters deep. The tunnel was built as part of an underground military facility. THE world's deepest metro, underground station is the Arsenalna Station on the Kiev Metro in Ukraine, at 107 meters deep.
Roding ValleyRoding Valley is London's least used tube station. Roding Valley is found on the central line. Roding Valley transports around the same number of passengers in 1 year, that London Waterloo does in 1 day.
