Volvo B7TL is a low-floor double-decker bus which was launched in 1999 and replaced the 2-axle version of Volvo Olympian (its 3-axle version was replaced by Volvo Super Olympian). It was built as the British bus operators seemed hesitant to purchase the B7L double decker with a long rear overhang (although some have since entered service in Glasgow, Scotland as 12m long double deckers). The B7TL chassis was initially built in Irvine, North Ayrshire, Scotland. In 2000, production was gradually transferred to Sweden. In mid-2004, production of MkII version of B7TL was started.
