Double-decker bus
The first commercial horse-drawn double-decker omnibuses were introduced in England in 1847 by Adams & Co. of Fairfield, Bow, then improved upon by John Greenwood, who introduced a new double-decker in 1852.

The red double-decker buses in London have become a national symbol of England. The majority of buses in London are double-deckers. A particularly iconic example was the AEC Routemaster bus, which had been a staple of the public transport network in London for nearly half a century following its introduction in 1956. Because of cited difficulties accommodating disabled passengers, the last remaining Routemasters in use finally retired from general service in 2005. Transport for London has continued to keep these vintage buses in operation on heritage route 15H, there was formerly a second heritage route (9H) but this ceased operation in 2014 due to low patronage and increased operation costs.
