The '''British Rail Class 40''' is a type of British railway [[diesel electric locomotive]]. A total of 200 were built by [[English Electric]] between 1958 and 1962. They were numbered D200-D399.{{cn|date=May 2024|reason=[[WP:UGC]] removed}}  Despite their initial success, by the time the last examples were entering service they were already being replaced on some top-level duties by more powerful locomotives. As they were slowly relegated from express passenger uses, the type found work on secondary passenger and freight services where they worked for many years. The final locomotives ended regular service in 1985.  The locomotives were commonly known as "Whistlers" because of the distinctive noise made by their turbochargers.<ref>{{cite web |title=Class 40 History |url=https://www.cfps.co.uk/history |website=Class 40 Preservation Society |date=9 March 2018 |access-date=28 March 2021}}</ref>

==Origins==

The origins of the Class 40 fleet lay in the prototype diesel locomotives ([[British Rail Class D16/1|LMS No. 10000 and 10001]] ordered by the [[London, Midland and Scottish Railway]] and [[British Railways]] and [[British Rail Class D16/2|D16/2]] ordered by [[British Railways]] between 1947 and 1954) and most notably with the [[Southern Region of British Railways|Southern Region]] locomotive No. 10203, which was powered by English Electric's 16SVT MkII engine developing 2,000 [[Horsepower|bhp]] (1,460 [[Watt|kW]]).<ref name="cfps1">{{cite web|url=http://www.cfps.co.uk/40story1.htm |title=Class 40 History Part 1 |archive-url=https://web.archive.org/web/20070713032405/http://www.cfps.co.uk/40story1.htm |archive-date=13 July 2007 |website=Class 40 Preservation Society |access-date=17 July 2007}}</ref> The bogie design and power train of 10203 was used almost unchanged on the first ten production Class 40s.

==Prototypes==
[[File:Brampton railway geograph-2400383-by-Ben-Brooksbank.jpg|thumb|left|One of the prototype locomotives, D205 on the [[Great Eastern Main Line|GEML]] in 1963.]]
British Railways originally ordered ten Class 40s, then known as "English Electric [[List of British Rail power classifications#Type 4|Type 4s]]", as evaluation prototypes.<ref name=TRM1290>{{cite magazine|title=Whistler Golden Jubilee|first=Andy|last=Flowers|magazine=The Railway Magazine|pages=14–21|date=October 2008|volume=154|issue=1,290|issn=0033-8923}}</ref> They were built at the [[Vulcan Foundry]] in [[Newton-le-Willows]], [[Lancashire]].<ref name="rcent">{{cite web|archive-url=https://web.archive.org/web/20030629023310/http://www.therailwaycentre.com/Pages%20Loco/Recognition%20loco/Illus_40.html |archive-date=29 June 2003 |title=Class 40 Page |url=http://www.therailwaycentre.com/Pages%20Loco/Recognition%20loco/Illus_40.html |website=The Railway Centre |access-date=18 July 2007 |url-status=usurped}}</ref> The first locomotive, D200, was delivered to [[Stratford Works|Stratford]] on 14 March 1958. Following fitter and crew training, D200 made its passenger début on an express train from [[Liverpool Street station|London Liverpool Street]] to {{stnlnk|Norwich}} on 18 April 1958.<ref name="cfps1" /> Five of the prototypes, Nos. D200, D202-D205, were trialled on similar services on the former [[Great Eastern Railway|Great Eastern]] routes, whilst the remaining five, Nos. D201, D206-D209, worked on Great Northern services on the [[East Coast Main Line]].

[[Brian Robertson, 1st Baron Robertson of Oakridge|Sir Brian Robertson]], then chairman of the [[British Transport Commission]], was less than impressed, believing that the locomotives lacked the power to maintain heavy trains at high speed and were too expensive to run in [[Multiple working|multiple]] – opinions that were later proved to be correct. Airing his views at the regional boards prompted others to break cover and it was agreed that later orders would be uprated to 2,500&nbsp;hp (a change that was never applied). Direct comparisons on the [[Great Eastern Main Line]] showed they offered little advantage over the [[BR Standard Class 7|"Britannia" class]] steam locomotives when driven well, and the Eastern Region declined to accept further machines as they deemed them unsuitable to replace the Pacific steam locomotives on the [[East Coast Main Line]],<ref name="sirbr">{{cite book |title=British Rail Standard Diesels of the 1960s |page=94 |publisher=Ian Allan Publishing}}</ref> preferring to hold on until the [[British Rail Class 55|"Deltic" Class 55]] diesels were delivered.

The [[London Midland Region of British Railways|London Midland Region]] was only too pleased, as the Eastern Region's decision released additional locomotives to replace their ageing steam fleet. The [[West Coast Main Line]] had been starved of investment for many years and the poor track and generally lower speeds (when compared to the East Coast route) suited Class 40s, as the need to hold trains at speed for long periods simply did not exist and it better took advantage of their fairly rapid acceleration.

==Production==

Scanned slide.]]
Following the mixed success of the prototypes, another 190 locomotives were ordered by British Railways, and were numbered from D210 to D399. All were built at Vulcan Foundry, except one batch of twenty (Nos. D305–D324) which were built at [[Robert Stephenson and Hawthorns]] factory in [[Darlington]]. All the locomotives were painted in the British Railways diesel green livery, and the final locomotive, D399, was delivered in September 1962.<ref name="cfps2">{{cite web |url=http://www.cfps.co.uk/40story2.htm |title=Class 40 History Part 2 |archive-url=https://web.archive.org/web/20070804165411/http://www.cfps.co.uk/40story2.htm |archive-date=4 August 2007 |website=Class 40 Preservation Society |access-date=23 July 2007}}</ref>

Batches of the class were built with significant design differences, due to changes in railway working practices. The first 125 locomotives, Nos. D200–D324, were built with steam-age 'disc' headcode markers,<ref name=Rail84-7071>{{cite magazine|title=Whistle while you work|pages=70–71|issue=84|date=September 1988|magazine=[[Rail (magazine)|Rail]]|publisher=EMAP National Publications|issn=0953-4563|oclc=49953699}}</ref> which were used to identify services. Later, it was decided that locomotives should display the four character [[train reporting number]] (or headcode) of the service they were hauling, and Nos. D325–D344 were built with 'split' headcode boxes,<ref name=Rail84-7071 /> which displayed two characters either side of the locomotive's central gangway doors. Another policy decision led to the discontinuing of the gangway doors (which enabled train crew to move between two or three locomotives in multiple). The remaining locomotives, Nos. D345–D399, carried a central four-character headcode box.<ref name=Rail84-7071 /> In 1965, seven of the first batch of locomotives, Nos. D260–D266, which were based in Scotland, were converted to the central headcode design.<ref name=Rail84-7071 /><ref>{{cite book |last=Haresnape |first=Brian |title=British Rail Fleet Survey 3: Production Diesel-Electrics Types 4 and 5 |edition=2nd |date=June 1984 |orig-year=1982 |publisher=[[Ian Allan Publishing|Ian Allan]] |location=Shepperton |isbn=0-7110-1450-7 |id=CX/0684 |pages=22–26, 27 }}</ref><ref>{{cite book |last=Strickland |first=D.C. |title=D+EG Locomotive Directory |date=March 1983 |publisher=Diesel & Electric Group |location=Camberley |isbn=0-906375-10-X |page=96 }}</ref>

From 1973, locomotives were renumbered to suit the [[TOPS]] computer operating system, and became known as 'Class 40'. Locomotives D201 to D399 were renumbered in sequence into the range 40&nbsp;001 to 40&nbsp;199. The first built locomotive, D200, was renumbered 40&nbsp;122, which was vacant due to the scrapping of D322 as the result of accident damage.

==The named 40s==

[[File:Andania's Nameplate.jpg|thumb|right|D213's Andania nameplate, preservation-era image]]
Locomotives in the range D210–D235 were to be named after ships operated by the companies [[Cunard Line]], [[Elder Dempster Lines]], and [[Canadian Pacific Steamships]], as they hauled express trains to Liverpool, the home port of these companies. The only locomotive not to carry a name was D226 which was to carry the name ''Media'' but never did so. From approximately 1970, with Class 40s no longer working these trains, the nameplates were gradually removed,<ref name="cfps2" /> so that by 1973 contributors to [[Railway World]] were reporting 7 different locomotives running without nameplates, all observed in North Wales.<ref>{{cite magazine| date = November 1973| title = Motive power miscellany| magazine = Railway World| location = Shepperton| publisher = Ian Allan| volume = 34| issue = 402| pages = 490–491}}</ref> However the [[Ian Allan Publishing|Ian Allan]] Motive Power Combined Volume (a list of all operational locomotives published annually for enthusiasts) was still listing the names of all officially named Class 40 locomotives in 1980<ref>{{cite book |title = British Rail Motive Power Combined Volume |publisher = Ian Allan |year = 1980 |page = 32 |isbn = 0-7110-1020-X }}</ref> despite none having carried their nameplates for many years.

A series of unofficial names were applied to the Class 40s by enthusiasts and enthusiastic depot staff. Some locos ran in service with these names applied for many months, others were painted out within days.

The locos to carry these unofficial names were:
* 40 060 'Ancient Mariner' (while in departmental duties as 97 405)
* 40 104 'Warrior'
* 40 129 'Dracula'
* 40 131 'Spartan'

The Class 40s operated in all areas of British Railways although sightings in the Western and Southern Regions have always been exceptionally rare and usually the result of special trains and/or unusual operational circumstances, but examples have been recorded such as D317 hauling a parcels train between Micheldever and Basingstoke on 3 July 1967,<ref>{{cite book | last =Vaughan | first =John | title =Diesels on the Southern | publisher =Ian Allan | date =1980 | location =Shepperton | page =67 | isbn =0-7110-0989-9}}</ref> and D335 operating the 07:35 Oxford to Paddington and 10:16 Paddington - Birmingham on 29 June 1971.<ref>{{cite magazine| title = Motive power miscellany| magazine = Railway World| location = Shepperton| publisher = Ian Allan| publication-date = September 1971| volume = 32| issue = 376| page = 416}}</ref> A review of the areas of operation published towards the end of the class's operational life showed no regular operational service on the [[Southern Region of British Railways|Southern Region]], and the only parts of the [[Western Region of British Railways|Western Region]] regularly visited were the [[Cambrian Line]] between [[Shrewsbury railway station|Shrewsbury]] and [[Aberystwyth railway station|Aberystwyth]], and freights on the [[Gloucester]] to [[Severn Tunnel Junction Marshalling Yard|Severn Tunnel Junction]] route.<ref>{{cite book | last =Dyer | first =Malcolm | editor-last=Oakley | editor-first=Michael | title =BR Class 40 Diesels | publisher =Bradford Barton | date =1982 | location =Truro | page =24 | isbn =0-85153-430-9}}</ref>

After the early trials the majority of '''Class 40s''' were based at depots in northern England, notably [[Longsight Diesel TMD|Longsight]], [[Carlisle Kingmoor TMD|Carlisle Kingmoor]], and [[Wigan Springs Branch TMD|Wigan Springs Branch]] on the [[London Midland Region of British Railways|Midland Region]], and [[Thornaby TMD|Thornaby]] and [[Gateshead TMD|Gateshead]] on the [[Eastern Region of British Railways|Eastern Region]].

The heyday of the class was in the early 1960s, when they hauled top-link expresses on the [[West Coast Main Line]]<ref>{{cite magazine|title=West Coast 'Whistlers'|pages=20–23|magazine=Rail Express|issue=224|date=January 2015|issn=1362-234X}}</ref> and in [[East Anglia]]. 

Like many diesel locomotive types of the time, they suffered criticism for reliability. The train heating boilers were a particular early problem on the Class 40s, requiring strict maintenance and were fairly complicated to operate. Late Autumn 1958 on the Great Northern line saw that, on six out of ten days, the ''Flying Scotsman'' service failed to produce a diesel, and ran late with a steam loco deputising. Breakdowns were common. The biggest problem the class encountered was their poor power-to-weight ratio. They lacked the versatility of the [[British_Rail_Class_37|Class 37s]], being either too heavy or too underpowered, for the work allocated. <ref>{{Cite web|url=https://www.cfps.co.uk/history|title=History|date=9 March 2018}}</ref>

However, the arrival of more powerful diesels such as the [[British Rail Class 47|Class 47]], [[British Rail Class 50|Class 50]], [[British Rail Class 55|Class 55]], and the later [[InterCity 125]], together with the [[Railway electrification system|electrification]] of the West Coast Main Line, meant that the fleet was gradually relegated to more mundane duties.

[[File:40013 Manchster Piccadilly.jpg|thumb|left|40013 (without nameplates) at Manchester Piccadilly in 1983.]]
In later life the locomotives were mainly to be found hauling heavy freight and passenger trains in the north of England and Scotland.  As more new rolling stock was introduced, their passenger work decreased, partly due to their lack of [[Electric train supply|electric train heating]] (D255 was fitted with electric train heating for a trial period in the mid-1960s) for newer passenger coaches. They lost their last front-line passenger duties – in Scotland – in 1980, and the last regular use on passenger trains was on the [[North Wales Coast Line]] between Holyhead, Crewe and Manchester, along with regular forays across the Pennines on Liverpool to York and Newcastle services.

Throughout the early 1980s Class 40s were common performers on relief, day excursion ([[adex]]) and holidaymaker services along with deputisation duties for electric traction, especially on Sundays between Manchester and Birmingham. This resulted in visits to many distant parts of the network. It would be fair to say that few routes in the London Midland and Eastern regions did not see a Class 40 worked passenger service from time to time. Regular destinations included the seaside resorts of Scarborough, Skegness and Cleethorpes on the Eastern region, with Blackpool and Stranraer being regularly visited on the West Coast.

Much rarer workings include visits to London's Paddington and Euston stations, Norwich, Cardiff and even Kyle of Lochalsh. The fact that 40s could turn up almost anywhere resulted in them being followed by a hard core of [[Railfan|bashers]], enthusiasts dedicated to journeying over lines with rare traction for the route.

=== Withdrawal ===

[[File:40175 & 40010 Swindon Works 28.10.82 (9125467408).jpg|thumb|right|40175 and 40010 at Swindon in 1982 - both had been withdrawn the previous year <!--and are in the process of being scrapped?-->]]
Withdrawal of the Class 40s started in 1976, when three locomotives (40&nbsp;005, 40&nbsp;039 and 40&nbsp;102) were taken out of service.<ref name=TRM1290 /> At over 130 tons the Class were by then considered underpowered. In addition, some were found to be suffering from fractures of the plate-frame bogies (due mainly to inappropriate use on wagon-load freight and the associated running into tightly curved yards{{citation needed|date=February 2020}}), and spares were also needed to keep other locomotives running.

Also, many Class 40s were not fitted with [[Air brake (rail)|air braking]], leaving them unable to haul more modern freight and passenger vehicles. Despite this, only seventeen had been withdrawn by the start of the 1980s.{{cn|date=May 2024|reason=[[WP:UGC]] removed}} The locomotives became more popular with [[Railfan|railway enthusiasts]] as their numbers started to dwindle.

Withdrawals then picked up apace, with the locomotives which lacked air brakes taking the brunt of the decline. In 1981, all 130 remaining locomotives were concentrated in the [[London Midland Region (British Railways)|London Midland region]] of BR. Classified works overhauls on the Class 40s were also gradually phased out, only 29 members of the class had a full classified in 1980, and the final two emerged from Crewe Works in 1981. The last to receive a classified overhaul was 40&nbsp;167 in February 1981.

After that, numbers dwindled slowly until, by the end of 1984, there were only sixteen still running. These included the pioneer locomotive, 40&nbsp;122, which, having been withdrawn in 1981, was reinstated in July 1983 and painted in the original green livery to haul rail enthusiasts' specials. The last passenger run by a Class 40, apart from 40&nbsp;122, occurred on 27 January 1985, when 40&nbsp;012 hauled a train from [[Birmingham New Street railway station|Birmingham New Street]] to [[York railway station|York]].<ref name=TRM1290 /> All the remaining locomotives except 40&nbsp;122 were withdrawn the next day.<ref name=TRM1290 />

The majority of Class 40s were cut up at Crewe, Doncaster, and Swindon works.
Crewe works dismantled the most 40s, the totals are listed below.
* [[Crewe Works]] scrapped 65 locos
* [[Doncaster Works]] scrapped 64 locos
* [[Swindon Works]] scrapped 54 locos.

The other ten locos to be scrapped were cut at Derby, Glasgow, Inverkeithing, and [[Vic Berry]] at Leicester.

1981 and 1983 saw the highest number of Class 40 withdrawals, a total of 41 locomotives being withdrawn both years.

The very last Class 40s to be cut up were 40&nbsp;091 and 40&nbsp;195 by A. Hampton contractors at Crewe Works in December 1988.

===D326: The Great Train Robbery, 1963===
[[File:Winter scenes along the Menai Strait and the Holyhead railway in the snow (1483197).jpg|thumb|D326 at [[Bangor railway station (Wales)|Bangor]] [[North Wales]] in December 1967]]
D326 (later 40 126) was the most famous Class 40, but for unfortunate reasons. The engine had an early chequered history.  It was classed as a jinxed loco by some railwaymen, with some drivers being reluctant to drive it. In 1963 it was involved in the infamous "[[Great Train Robbery (1963)|Great Train Robbery]]", and a year later in August 1964 a [[secondman]] was electrocuted<ref name=RE1>{{cite magazine|title=40126 - Loco with a dark history|first=C.H.|last=Wrate|pages=28–29|date=November 1983|magazine=[[Rail (magazine)|Rail Enthusiast]]|publisher=EMAP National Publications|issn=0262-561X|oclc=49957965}}</ref> when washing the windows. Finally, in August 1965, it suffered total brake failure with a maintenance train at [[Birmingham New Street railway station|Birmingham New Street]] and hit the rear of a freight train, injuring the guard.<ref name=RE1 /> It then settled down and had a normal life until it was scrapped in 1984.

40126 was withdrawn from service on 15 February 1984. Upon withdrawal the locomotive was offered to the [[National Railway Museum]] at York as an exhibit loco regarding its past history.  However, the NRM declined and it was scrapped at Doncaster Works with indecent haste, no doubt to stop any pillaging souvenir hunters. Other famous "40s" include 40 106, which was the last one to remain in BR green livery, and 40 009, the last 40 to still have vacuum brakes only.<ref>{{cite web |url=http://cfps.co.uk/class40story.htm |title=Welcome to the Class 40 Preservation |access-date=23 July 2014 |archive-url=https://web.archive.org/web/20140726165633/http://cfps.co.uk/class40story.htm |archive-date=26 July 2014 |url-status=dead  }}</ref>

==In popular culture==

D306 Preserved 40106 appeared as D326 with added fake split head code boxes in the 1988 comedy/drama movie ''[[Buster (1988 film)|Buster]]'' with the robbery scenes shot at Swithland Sidings and Rothley on the [[Great Central Railway]] Leicestershire.

==Preservation==
Seven locomotives and one cab end (40&nbsp;088) have been preserved on [[heritage railway]]s, including the first built, D200, and the departmental locomotives: 97406, 97407 and 97408. Not all locomotives may be carrying their names currently and these are noted in the chart below.{{clarify|date=June 2014}}

Of the seven class 40s to be preserved, all except for 40118 have run in preservation and three have run on the main line in preservation; these are D200 (40122), D213 (40013) and D345 (40145). As of 2018, D213 and D345 are operational on the main line.{{citation needed|date=August 2018}}

In 2010, [[Hornby Railways]] launched its first version of the BR Class 40 which was a remotored Lima model that Hornby had acquired, which is basic representation of the prototype as part of their Railroad range in BR Blue in [[OO gauge]].<ref>{{cite web|url=http://hornbyguide.com/class_details.asp?classid=162|title=Hornby BR Class 40|work=Hornby Railways Collector Guide|access-date=1 February 2020}}</ref>

[[British N gauge]] models of the Class 40 have been produced by [[Graham Farish]], representing the main three headcode versions. A BR Green version of D211 ''Mauretania'' received a positive review from [[The Railway Magazine]] Guide to Modelling in 2017.<ref>{{cite magazine|url=https://issuu.com/mortons-digital/docs/rmm_24112017/8|title=Graham Farish 'Whistler'|magazine=The Railway Magazine Guide to Modelling|first=Nigel|last=Burkin|pages=8–9|issue=12|date=December 2017|accessdate=20 March 2021}}</ref>
