Next time you visit London and get on one double-decker to go up and down Oxford Street, the Strand or Whitehall with the aim of obtaining the perfect tourist certificate, they probably won't realize it, but perhaps they will no longer use one of the icons of an era and a city: the famous red double-decker buses, the Routemasters, introduced in 195 and get off while moving. In 2005 they were retired from service and in 2012 the New Routemaster was reintroduced – they called it Borismaster, because Boris Johnson promoted it when he was mayor –, to keep a cultural symbol alive.
