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.
Tillingbourne Bus Company
The first vehicle to be bought by Tillingbourne was a single-deck Chevrolet with 14 seats, which entered service on the launch of the company's first route in 1924. It was joined by a similar Overland Automobile bus later in the year. Two further vehicles had been purchased by 1928, when a depot fire destroyed three of the four buses. They were replaced by second-hand buses including an 18-seat Dennis and several Thornycroft A2 vehicles. From November 1934 until the outbreak of World War II, these were progressively replaced by new buses, also built by Thornycroft. The first double-deck vehicle to be bought was a Bristol K Type, which joined the fleet in 1959. Eight Guy Vixens were bought from London Transport between 1963 and 1964 to replace the entire previous fleet. These were succeeded by a wide variety of types, with Bedford coaches and buses the most numerous. In the 1970s, a number of second-hand Bristol SUL4A's, with ECW B36F bodies, were operated.
