The Tube
The Tube is a colloquial name for the London Underground, London's metro system. The underground railway has been described as the tube since 1890 when the first electric railway line running through deep-level tunnels was opened. Specific lines also have their own nicknames; the most widely used is the Waterloo and City Line's "The Drain".
The Tube was an innovative United Kingdom music television programme of the 1980s.
The Tube is also a colloquial name for television, especially in the United States. It arose because a cathode ray tube is the major component in conventional television sets.Other meanings
