The 1990s in the UK was an era of Britpop and the beginning of the information age. It also saw Labour come into power.
On the London Underground smoking had just been banned in the previous decade and paper tickets were still being used.
The decade saw a number of upgrades made to the network, including the £3.5bn Jubilee line extension. Construction began in 1993, and it opened in stages from May to December 1999.
The Central line was also upgraded to automatic operation in the 1990s, making it the second Underground line, after the Victoria line in the 1960s, to use this technology.
During the 1990s London Underground also experimented with giving each line its own moquette to give each line its separate identity.
Today the Tube handles up to five million passenger journeys a day. At peak times, there are more than 543 trains whizzing around the capital.
The network has expanded to 12 lines and serves 272 stations, making it one of the busiest metro systems in the world.
We've taken a look down memory lane on the London Underground in the 1990s.
