Getting around in LONDON A. Underground Over 3 million people a day use the Underground or Tube to get around in London. The Tube has 270 stations in many different parts of the city and 11 lines that can take you to any place you want. So, don't forget to have a Tube map with you before you start your journey! B. Red Double-Decker Bus You can see these red double-decker buses in London. They are tall but they are not very fast. Tourists like taking these buses because they can have a nice view of the city from the upper deck. C. Black Cab Black cabs are special taxis that have a lot of room for passengers and their luggage. Black cab drivers take a test of their knowledge of London, as they have to know all of the 25,000 streets within 10 km of the city centre!
