1 On October 25th 1911, the London General Omnibus Company ran their last horse-drawn omnibus. 2 Then the big red motor bus has been London's 'king of the road'. 3 Every day, thousands of Londoners use the big red buses to move around town. 4 The idea of the 'double decker' is actually much older than the motor bus; it is a continuation of the system in the age of horse-drawn vehicles, when some of the passengers sat inside, and the rest travelled on the roof. 5 Today the only open-topped buses are the special tourist buses. 6 The most famous London buses, however, are the Routemasters. 7 They have open platform at the back end and passengers can climb on and off when they want, even if the bus is moving . 8 The RM was taken out of use in June 2007 due to a law requiring busses to have access for disabled people. 9 The black London taxi cab is another traditional symbol of London. 10 It looks old-fashioned and clumsy, but in fact it's comfortable and speedy.
