The type was widely used in the United Kingdom and it was also successful in export market, with numerous examples shipped to countries such as India and South Africa.
After Leyland ended the production of the Leyland Titan in UK, Ashok Leyland of India took up production and marketed the bus in South Asia as the Ashok Leyland Titan, which is still in production.
Titans in London
When London Transport was established in 1933 it inherited a few hundred Leyland Titans from independent bus operators in London.
After World War II, London Transport bought more than 2,000 Leyland Titans specifically designed for use in London. They were designated as the RTL (1,631 built) and the wider variant RTW (500 built). In appearance they were very similar to the AEC-built RTs (4,825 built), the radiator shell being the most obvious difference (aside from the greater width of the RTWs).
