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.
Metro Manila Transit Corporation Double-Decker Bus
The Metro Manila double-decker bus was employed in the 1980s on the EDSA highway. The model most used was the Leyland Atlantean, a double-decker bus chassis manufactured by Leyland between 1958 and 1986. Leyland pioneered the design of rear-engined, front entrance double deck buses in the United Kingdom, allowing for the introduction of one-man operation buses, dispensing with the need for a conductor.
