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.
Double-decker tram
The earliest double-deck trams were horse drawn. The first electric double-deck trams were those built for the Blackpool Tramway in 1885, where Conduit tramcar No. 4 is the sole survivor of its class and is preserved at the National Tramway Museum in Crich, UK. They were common in the United Kingdom until the 1950s. London Transport was a heavy user of double-deck trams until the system closed in 1952. Apart from the Blackpool tramway, the Glasgow Corporation Tramways was the last urban British tramway to close, in 1962. Several tramcars have been preserved at the UK's National Tramway Museum, Beamish Museum, Black Country Living Museum, East Anglia Transport Museum, Heaton Park Tramway, Seaton Tramway, Summerlee Museum and the Wirral Transport Museum. Some have been preserved at New Zealand's Ferrymead Museum in Christchurch and MOTAT Museum in Auckland, which operates restored Wellington double-deck tramcar, No. 47, which operated in 1906 and also has Auckland double-deck tramcar, No. 17, in storage. The last double-deck tram built in the UK was Blackpool "Jubilee" Class No. 762, which entered service in 1982. However, it was originally built in 1935 as Blackpool "Balloon" Class No. 251, later renumbered No. 714. Its rebuild as No. 762 gave it a longer body and its pointed ends were replaced with rectangular ones. It was the second and final rebuild of two Blackpool "Balloon" tramcars into "Jubilee" tramcars, following on from "Jubilee" Class No. 761. Unlike No. 761, "Jubilee" tramcar No. 762 retained its central doors as exits for improved passenger flow at stops. For these reasons, it was considered to be an entirely new tram and on this basis, when it was retired in 2011, it was gifted to the National Tramway Museum in Crich.
