The London Underground celebrates its 160 year anniversary this year, making it the oldest underground network in the world.
The whole network began with the Metropolitan Railway which constructed a railway that covered 6km (3.75 miles) and opened on January 10 1863.
The railway proved extremely popular from its first day, carrying 36,000 passengers and more railways were quickly proposed.
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.
Ahead of the first anniversary of the Elizabeth line we’ve taken a look at the history of the London Underground lines.
