The Alexander ALX400 was the first low-floor bus body built in the
United Kingdom, first appearing in 1997. The first ALX400s were placed
on the DAF DB250LF chassis, closely followed by the Dennis Trident. 2000
saw the launch of the Volvo B7TL / ALX400 combination. The ALX400 soon
became one of the more popular low-floor double-decks not only in
London, but in the UK. The introduction of the Enviro 400 model in 2005
spelt the end of the ALX400, and in 2006 the model was discontinued. A
large number of ALX400s were purchased by Arriva, Stagecoach and First,
along with smaller orders from the Go-Ahead group. Utilising a number of
superb images and informative captions, David Beddall documents the use
of this bus in London.
