London transport
when you go to london,one of the first things you notice are the famous london double—decker buses.They are red.
If y travd on top you get a wonderful view of london.If there are a lot of people waiting for the bus, you take a place in the queue.If a bus is full up when it arrives,you cannot get on it,but you wait for the next on.
Passengers can smoke upstairs(on top) but not downstairs.When you get on,you pay the conductor for the tocket.But if you are in a hurry,you take the underground or tube, as Londoners call it.There are eight lines,each of them coers very long distances.In some staions there are electric lifts and long escalators to carry passengers up and down.If you want to go outside London,you go by train. The principal London stations are：Victoria, King"s Cross,Waterloo,Charing cross,Paddington,Euston,Liverpool St.and London Bridge.
