The Volvo B7TL is a low-floor double-decker bus chassis which was launched in 1999 and replaced the 2-axle version of the Volvo Olympian (its 3-axle version was replaced by the 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 12 m long double deckers).
