Stamford Hill in March 2010 The Alexander ALX400 proved to be a major success with the major operators of the United Kingdom, with large numbers of the buses serving
London as well as the rest of the UK.
Arriva London took delivery of the first ALX400 in May 1998, numbered DLA1 and built on DAF DB250LF chassis, which was also London's first low-floor double decker. Arriva London went on to order 388 more ALX400s on DAF DB250LF chassis between 1998 and 2005; between 2017 and 2019, DLA1 was restored to as-new condition by
Alexander Dennis with the initial intention for display at the
London Transport Museum before later being sold into private ownership. From its introduction until 2006, the Alexander ALX400 on the Dennis Trident 2 chassis was the favoured 2-axle double-decker bus model for the
Stagecoach Group.
Stagecoach London operated the most ALX400s in the group, continuously taking delivery of 998 ALX400s to its various garages from 1998 to 2006. Stagecoach's first low-floor double-decker bus outside London was one of a pair of ALX400-bodied Dennis Tridents that were delivered to
Stagecoach Manchester in 1998; this bus was later donated to and restored by the
Museum of Transport, Greater Manchester. Deliveries were made to Stagecoach operations across the United Kingdom such as in
Oxford,
Devon,
Canterbury,
Cambridge, and
Kingston upon Hull, among others. In London, other operators of Alexander ALX400s on Dennis Trident 2 and Volvo B7TL chassis included Arriva London, who took delivery of 179 ALX400-bodied B7TLs alongside their DAF DB250LFs; and
Armchair Passenger Transport, who took 22 ALX400-bodied Tridents in 2002. All but ten were fitted on Volvo B7TL chassis, with a batch of ten fitted on the TransBus Trident chassis delivered in 2003 to compare against the B7TLs with a view to splitting future orders. Most of these featured 76 seat single door bodies although there were various seating capacities used on a small minority of rail and airport link services; Summerhill based AV 116-130 were built with dual-door bodies for use on the Airlink services. Alexander ALX400s on both the Dennis Trident 2 and Volvo B7TL chassis were also extensively delivered to the
National Express's bus operations in the
West Midlands,
Coventry and
Dundee, with over 400 orders received for all three operations from 2001 to 2005.
Translink of Northern Ireland purchased over 150 Alexander ALX400s on Volvo B7TL chassis for its
Ulsterbus and
Citybus (later rebranded Metro) operations between 2001 and 2006, with the first batch of 20 delivered to Citybus in 2001 marking the return of double-decker buses to
Belfast for the first time since their withdrawal in 1989. Outside London,
Arriva ordered ALX400s on both the Dennis Trident and Volvo B7TL chassis in comparatively smaller numbers compared to Stagecoach and the FirstGroup. On the Volvo B7TL chassis, 20 ALX400s were delivered to
Arriva Yorkshire in 2000, 49 were delivered to
Arriva Medway Towns in 2004 as part of
Operation Overdrive, two ALX400s were delivered to
Arriva North East in 2005 as part of a larger investment in 24 new buses for the region, and 30 ALX400s were delivered to
Arriva Merseyside in 2006. On the Dennis Trident chassis, 30 ALX400s were delivered to
Arriva Shires & Essex in 2000.
UK North, who had four ALX400s on DAF DB250 chassis delivered in 1999; the
Oxford Bus Company, who had 20 dual-door ALX400s on Dennis Trident 2 chassis delivered for use on the Oxford
Park and Ride in 1999;
East Yorkshire Motor Services and
Finglands Coachways, who took delivery of two ALX400s each on Dennis Trident 2 chassis for evaluation against Plaxton President-bodied Volvo B7TLs in 2000; and
Newport Transport, who took delivery of six ALX400s on Dennis Trident chassis in 2000. In late 2005,
Alexander Dennis launched the
Enviro400 model, intended as a replacement for the ALX400. Despite the bulk of the 2006 Stagecoach double-decker bus order favouring the Enviro400 model, also chosen by London operator
Metroline, in July 2006 Dublin Bus placed a repeat order for 100 ALX400 on Volvo B7TL chassis. Production of the ALX400 bodywork ceased after the delivery of these 100 ALX400-bodied Volvo B7TLs between late 2006 and early 2007. ==References==
