Big Red London Buses
What is the best-known symbol of London? Big Ben? St Paul's Cathedral? Can it be the big red London double-decker bus?
It certainly can be. Every day, thousands of Londoners use the big red buses to move around the town. Every tourist knows that a one-day London bus pass can be used on all bus routes. London bus can offer a wonderful way to see the sights of Britain's capital city.
Since 1911 the big red motor bus has been London's 'king of the road'. The idea of the 'double-decker' is much older than the motor bus. Until the 1930s the 'double-decker' bus had no roof. Some passengers sat inside, and the rest travelled on the roof. It was too bad if it was raining! But then all new buses became equipped with roofs over the upper deck.
Today the only open-topped buses are the special tourist buses.
The most popular buses are those from the 'Routemasters' which date from the 1950s and 60s. It is popular because it has an open platform at the back end and passengers can climb on and off when they want, even if the bus is moving (though this is not recommended!). These buses were designed specially for London, by people who knew what London needed. They have served their purpose well!
