The Alexander ALX400 (later known as the TransBus ALX400 and the Alexander Dennis ALX400) is a 2-axle double-decker bus body built by Walter Alexander Coachbuilders (later by TransBus International/Alexander Dennis). It was one of the ALX-series bodywork, all of which (except the ALX100) featured the same designs on the front and rear panels that were originally designed for the new generation of mainly low-floor bus chassis produced since the late 1990s.

==Description==

First unveiled in 1997, the Alexander ALX400 replaced the step-entrance Alexander R-series and was fitted to numerous chassis, including the Dennis/TransBus Trident 2, the DAF/VDL DB250LF and the Volvo B7TL.

Various seating configurations were available, with Transport for London (TfL) specification models fitted with a central exit door. There are typically 45 seats on the upper deck, and between 17 and 22 seats on the lower deck depending on chassis variant and length. Longer models for use elsewhere have up to 47 seats on the upper deck, and 24 below with a central door. Stagecoach subsidiaries outside London have ALX400s on long-wheelbase Dennis Trident 2 chassis, fitted with 51 seats upstairs (47 on later models) and 28 downstairs. These buses have been used all over the UK, in major cities including London, Birmingham, Manchester and Newcastle.

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.{{cite news |last=McLean |first=Allan |date=20 May 1998 |title=Alexander unveils new design for buses |work=The Scotsman |location=Edinburgh |page=24 |id={{ProQuest|326686904}}}} 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.{{Cite tweet |author=Alexander Dennis |user=ADLbus |author-link=Alexander Dennis |number=1123517988026580992 |title=We are proud to have been able to contribute to the preservation of London's first low-floor double decker by funding and carrying out its full restoration over the last two years. @Arriva_London will now donate the Alexander ALX400-bodied DAF to the @ltmuseum collection. |access-date=10 August 2021}}{{cite magazine |last=Larkin |first=Nick |url=https://cbwmagazine.com/dla-desires/ |title=DLA desires |date=27 September 2022 |magazine=Coach & Bus Week |location=Peterborough |access-date=28 September 2022 |url-access=subscription}}

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.{{cite book|last=Wharmby |first=Matthew|title=The London Dennis Trident|url=https://books.google.com/books?id=vrs1EAAAQBAJ|access-date=8 August 2021|date=31 July 2021|publisher=Pen & Sword|location=Barnsley|isbn=978-1-5267-8694-4}}{{rp|280}}{{cite magazine |last=Williams |first=Mark |url=https://archive.org/details/cbw-issue291/page/21/mode/1up |date=16 October 1997 |title=Stagecoach orders hundred Tridents |magazine=Coach & Bus Week |issue=291 |page=21 |location=Peterborough |publisher=Emap |access-date=23 April 2024}} 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.{{cite magazine|last=Larkin |first=Nick |url=https://cbwmagazine.com/historic-trident-restored/ |title=Historic Trident restored |date=5 December 2023 |magazine=Coach & Bus Week |location=Peterborough |access-date=5 December 2023 |url-access=subscription}} Deliveries were made to Stagecoach operations across the United Kingdom such as in Oxford,{{cite news |title=Stagecoach launches partnership with Oxford Brookes |url=http://busandcoach.com/65news4.html |url-status=dead |work=Bus & Coach Professional |archive-url=https://web.archive.org/web/20031229080534/http://busandcoach.com/65news4.html |year=2003 |archive-date=29 December 2003 |access-date=3 June 2023}} Devon,{{cite magazine|date=Spring 2004 |title=Devon takes delivery of new Tridents |url=https://www.stagecoachgroup.com/~/media/Files/S/Stagecoach-Group/Attachments/media/publication-internal-newspaper/issue54 |magazine=On Stage|issue=54 |page=4 |publisher=Stagecoach Group |access-date=31 May 2023}}{{dead link|fix-attempted=yes|date=April 2024}} Canterbury,{{cite magazine |url=https://archive.org/details/buscoachbuyer-issue783/page/n5/mode/1up |date=24 September 2004 |title=New Canterbury QPS signed |magazine=Bus & Coach Buyer |issue=783 |page=6 |location=Spalding |publisher=Glen-Holland Ltd |access-date=30 November 2024}} Cambridge,{{cite book|last=Beddall|first=David|title=Cambus to Stagecoach East: A Fleet History, 1984–2020 |url=https://books.google.com/books?id=3M9xEAAAQBAJ |access-date=30 May 2023|date=30 August 2022|publisher=Pen & Sword|location=Barnsley|isbn=978-1-5267-8103-1|page=90}} and Kingston upon Hull,{{cite news |author= |title=Don't miss the bus on timetable changes |date=17 April 2007|newspaper=Hull Daily Mail|page=13|id={{ProQuest|333649110}}|quote=The timetable changes also coincide with Stagecoach introducing new high-tech double-decker buses on its 32 route, linking Bransholme and the city centre.

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.{{cite news |date=19 January 2001 |title=Express in £23m order for buses |work=Birmingham Post|page=26 |id={{ProQuest|323657912}}}}{{cite news |date=13 September 2003 |title=£4m on double deckers |work=Evening Mail |location=Birmingham |page=4 |id={{ProQuest|322504591}}}}{{cite news |last=Bain |first=Simon |date=31 May 2004 |title=Cameron and Hastie take the wheel as bus-builder goes back to its roots |work=The Herald|location=Glasgow |page=18 |id={{ProQuest|332868620}} |quote=The new company is expected to announce that it has already received an order worth £7.5m for 50 double-deckers for Travel West Midlands, the Birmingham bus operator.}} 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.{{cite news|url=https://www.belfasttelegraph.co.uk/news/double-deckers-go-back-on-city-streets/28348359.html |work=Belfast Telegraph|date=26 March 2001 |title=Double-deckers go back on city streets |access-date=6 April 2023}}{{cite press release |last=Stanczyk |first=Sarah |date=28 January 2003 |title=Translink Moves Public Transport into Top Gear |url=http://www.translink.co.uk/20030128newbuses.asp |url-status=dead |location=Belfast |publisher=Translink |archive-url=https://web.archive.org/web/20030626035410/http://www.translink.co.uk/20030128newbuses.asp |archive-date=26 June 2003 |access-date=6 April 2023}}{{cite news|url=https://www.irishtimes.com/news/translink-orders-200-new-buses-for-ni-fleet-1.1176387 |newspaper=The Irish Times|date=20 April 2005 |title=Translink orders 200 new buses for NI fleet |access-date=6 April 2023}}

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.
