The Leyland Titan was a chassis with a front-mounted engine designed to carry double-decker bus bodywork. It was built from 1927 to 1970 although production was suspended from 1942 to 1945 because of World War II.
Leyland made the chassis available to several bodybuilders including Northern Counties, Park Royal (AEC), Beadle, and Short Brothers as well as supplying complete vehicles.
