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.
