Wikipedia
A double-decker bus is a bus that has two storeys or decks. Double-decker buses are used for mass transport in the United Kingdom, Europe, Asia and many former European possessions an iconic example being the red London bus. Double-decker buses are also used in many other cities around the world.
Early double-deckers put the driver in a separate cab. Passenger access was via an open platform at the rear, and a conductor would collect fares. Modern double-deckers have a main entrance door at the front, and the driver takes fares, thus halving the number of bus workers aboard, but slowing the boarding process. The rear open platform, popular with passengers, was abandoned for safety reasons, as there was a risk of passengers falling when running and jumping onto the bus.
Double-deckers are primarily for commuter transport but open-top models are used as sight-seeing buses for tourists. William Gladstone, speaking of London's double-deck horse drawn omnibuses, once observed, "...the best way to see London is from the top of a bus".Elbert Hubbard Little Journeys to the Homes of Good Men and Great (1894–1918) William E. Gladstone The full quote is:
Then he asked if we were going to London. On being told that we were, he spoke for five minutes about the things we should see in the Metropolis. His style was not conversational, but after the manner of a man who was much used to speaking in public or to receiving delegations. The sentences were stately, the voice rather loud and declamatory. His closing words were: "Yes, gentlemen, the way to see London is from the top of a 'bus—from the top of a 'bus, gentlemen."Usage examples of "double-decker bus".
