The Leyland Olympian was a double-decker bus built by British Leyland/Leyland Bus in the United Kingdom from 1980 to 1993. The Olympian was built as a result of the Leyland Titan (B15), an integral double deck bus which was ordered en masse by London Transport. At the time there was a demand for non- integral vehicles; operators wishing to remain with more established manufacturers. Thus Leyland created the B45 project, which was named Olympian, in 1979. This was in many ways an update of the popular Bristol VR (Bristol Commercial Vehicles merged with Leyland in 1965), with many VR customers choosing Olympians. Later the Olympian also replaced the Leyland Atlantean. It was available in 2 lengths, with wheelbases of 4.95m and 5.64m, giving total lengths of 9.56m and 10.25m. Engines were either the Leyland TL11 unit (an 11.1-litre development of the Leyland O.680), or the ever-popular Gardner 6LXB or 6LXCT. Some later Olympians had Cummins L10 engines. One even had a 5LXCT.
