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.
Victoria Regional Transit System
The use of buses started in 1923 for outlying routes. Although trolley buses were tried in 1945, the transit system was completely converted to motor buses in 1948. In 1961 BC Electric became part of BC Hydro, a Crown corporation, before the transit system was moved to the crown agency that would become BC Transit. In 2000 Victoria became the first city in North America to use double decker buses in regular public transit service as well as the first city to use hybrid double-decker buses.
