context_page_description: 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, the most iconic example being the red London bus, namely the AEC Routemaster.
  Early double-deckers put the driver in a separate cab. Passenger access was via an open platform at the rear, and a bus 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 that "...the best way to see London is from the top of a bus".
