The Leyland Atlantean is a model of double-decker bus built by Leyland (with bodies added by a variety of companies) in the United Kingdom from 1958 to 1986.
It pioneered the design of rear-engined, front entrance double deck buses in the UK, allowing for the introduction of "one person operated" buses, dispensing with the need for a conductor.
