At the turn of the century, Volvo found itself in a three-way tussle
with Dennis and DAF to design and produce Britain's first low-floor
double-deck buses. The resulting B7TL was later into service in London
than its competitors, but quickly caught up to achieve parity with the
Dennis Trident. Two lengths were available and three bodies, by
Alexander, Plaxton and East Lancs. Between them, London's TfL-contracted
London bus operators took over two thousand Volvo B7TLs between 2000 and
2006, after which noise problems obliged Volvo to develop the B9TL and
its later B5LH hybrid. The Volvo B7TLs saw sterling service in the
capital for two decades, with the last leaving service in the first week
of 2021.
