LNER [[LNER Class A4|Class A4]] 4468 '''''Mallard''''' is a [[4-6-2]] ("Pacific") [[steam locomotive]] built in 1938 for operation on the [[London and North Eastern Railway]] (LNER) at [[Doncaster Works]] to a design of [[Nigel Gresley]]. Its [[Streamliner|streamlined]], [[wind tunnel]] tested<ref>{{Solomon-Masterpieces|page=28}}</ref> design allowed it to haul long-distance express passenger services at high speeds. On 3 July 1938, ''Mallard'' broke the world [[Railway speed record#Steam|speed record for steam]] locomotives at {{convert|126|mph|abbr=on}}, which still stands today.

While in [[British Rail]]ways days, regular steam-hauled rail services in the UK were officially limited to a {{convert|90|mph|abbr=on}} "line speed", before the [[Second World War]], the A4s had to run significantly above {{convert|90|mph|abbr=on}} just to keep schedule on trains such as the ''[[Silver Jubilee (train)|Silver Jubilee]]'' and ''[[The Coronation (train)|The Coronation]]'',<ref>{{cite book|title=Named Trains on LNER Lines|last=Yeadon|first=Willie B.|edition=Combined|publisher=Book Law Publications|isbn=1899624384|year=2004|page=157}}</ref> with the engines reaching 100&nbsp;mph on many occasions.<ref>{{cite book|title=The Gresley Pacifics|volume=2|last=Nock|first=O.S.|year=1974|publisher=David & Charles}}</ref><ref>{{cite book|title=Locomotives of the L.N.E.R.

The locomotive is {{convert|70|ft|m|abbr=on|adj=mid}} long and weighs 165 long tons (168 tonnes, 369,600 lbs), including the [[Tender locomotive|tender]]. It is painted in LNER [[Order of the Garter|garter]] blue with red wheels and steel rims.

''Mallard'' is preserved at the [[National Railway Museum]] in [[York]] as part of the [[National Collection]].

==History==
[[File:60022 Stoke Bank 090662.jpg|thumb|60022 ''Mallard'' descending Stoke Bank in June 1962]]
In 1936, [[Nigel Gresley]], the chief mechanical engineer of the LNER, ordered a new batch of six [[4-6-2]] "Pacific" [[LNER Class A4|Class A4]] engines to be built at [[Doncaster Works]].<ref name=hale>{{cite book|last=Hale|first=Don|title=Mallard: How the 'Blue Streak' Broke the World Steam Speed Record|date=2009|publisher=Long Preston|isbn=978-1-842-62673-3}}</ref>{{rp|223}} The A4s were known for their distinct streamlined and aerodynamic design and designed for hauling long distance express passenger services at high speeds. The first batch comprised four locomotives which entered service in 1935 and had "Silver" in their names as they were to haul the non-stop ''Silver Jubilee'' service between London King's Cross and Newcastle.

The six new A4s were named after a bird, influenced by Gresley's fondness of breeding wild birds, and incorporated some modifications to maximise the possibilities of the original streamlined design.<ref name=hale/>{{rp|221}} This included a new, state-of-the-art double [[Kylchap]] chimney and blastpipe, allowing the smoke to be distributed more freely.<ref name=hale/>{{rp|224}} However, the problem of smoke being dispersed at the front of the locomotive, giving drivers only a narrow viewing window, remained unsolved, and Gresley was determined to find a solution, using ''Mallard'', the 28th A4 locomotive as a test. It was solved after a wooden 1/12th scale model of ''Mallard'' underwent smoke tests in a [[wind tunnel]] made of [[plasticine]]. After a period of testing, a solution to deflect the smoke was found, and the modification was incorporated into ''Mallard''{{'}}s final design.<ref name=hale/>{{rp|225–227}}

''Mallard'' was released from Doncaster Works and entered service on 3 March 1938, carrying the number of 4468. It wore a variety of liveries throughout its career, these were: garter blue as 4468, LNER wartime black from 13 June 1942, later wartime black with the tender marked as "NE" from 21 October 1943 as 22 with yellow small stencilled numbers, post-war garter blue with white and red lining from 5 March 1948 with stainless steel cabside number 22, British Railways dark blue as 60022 from 16 September 1949, [[Spring green|Brunswick green]] from 4 July 1952, and its original LNER garter blue for preservation in 1963.

The A4 class was built with streamlined valances, or side skirting, but they were removed on 13 June 1942 during wartime to ease maintenance, and replaced in preservation in 1963.

''Mallard'' was fitted with twelve boilers during its 25-year career. These boilers were: 9024 (from construction), 8959 (from 4496 ''Golden Shuttle'', 13 June 1942), 8907 (from 2511 ''Silver King'', 1 August 1946), 8948 (from 31 ''Golden Plover'', ''Walter K Whigham'', 10 January 1951), 29301 (from 60019 ''Bittern'', 4 July 1952), 29315 (from 60014 ''Silver Link'', 23 April 1954), 29328 (new-build boiler, 7 June 1957), 29308 (from 60008 ''Dwight D. Eisenhower'', 27 August 1958), 29310 (from 60009 ''Union of South Africa'', 9 March 1960) and 27965 (from 60009 ''Union of South Africa'', 10 August 1961).

''Mallard'' has had seven tenders throughout its career. It started off with a non-corridor tender in 1938, had corridor-design tenders during its British Railways days, and was fitted with a non-corridor tender in 1963 to recreate its original appearance. The tenders it has been fitted with are: 5642 (3 March 1938 – 14 March 1939), 5639 (5 May 1939 – 16 January 1948), 5323 (5 March 1948 – 12 March 1953), 5648 (12 March 1953 – 21 July 1958), 5330 (27 August 1958 – 30 May 1962), 5651 (30 May 1962 – 25 April 1963) and 5670 (current tender, masquerading as original tender 5642).

The original non-corridor tender 5642 was later coupled to sister locomotive 60026 ''Miles Beevor'' when it was withdrawn on 21 December 1965, but later came into the possession of the A4 Preservation Society, which had purchased this locomotive from the scrapyard to assist the restoration of classmate 4498 ''Sir Nigel Gresley''. It was scrapped in 1973 as being surplus to requirements, by which time it had also donated parts to the restoration of A3 class locomotive [[LNER Class A3 4472 Flying Scotsman|4472 ''Flying Scotsman'']], which had recently returned from America and was being restored at Derby Workshops.

''Mallard'' was allocated to three sheds during its career: [[Doncaster Carr rail depot#Site history|Doncaster]], transferring on 21 October 1943 to Grantham and on 11 April 1948 to [[Kings Cross Top Shed]].

===1938 speed record===
On 3 July 1938, ''Mallard'' claimed the world [[Railway speed record#Steam|speed record for steam]] locomotives at {{convert|126|mph|abbr=on}} during a trial of the new quick-acting Westinghouse QSA brake. The speed was achieved during the downward grade of [[Stoke Bank]], south of [[Grantham railway station|Grantham]] at milepost&nbsp;90¼, between [[Little Bytham]] and [[Essendine railway station|Essendine]] stations. ''Mallard'' hauled a seven-coach train, including a [[dynamometer car]] with apparatus to record the speed. The previous record of {{convert|200.4|km/h|abbr=on|order=flip}} was set in Germany in 1936 by [[DRG Class 05]] No. 002. ''Mallard'' was four months old at the time of the record, and was operated by driver Joseph Duddington—renowned within the LNER for taking calculated risks—and fireman Thomas Bray.<ref>{{cite news |url=https://www.yorkshirepost.co.uk/news/Men-who-served-on-Mallard.4234814.jp |title=Men who served on Mallard prepare to be reunited with famous locomotive |newspaper=Yorkshire Post|date=2008-06-30|url-status=dead|archive-date=2012-05-27|archive-url=https://web.archive.org/web/20120527132713/http://www.yorkshirepost.co.uk/news/around-yorkshire/local-stories/men-who-served-on-mallard-prepare-to-be-reunited-with-famous-locomotive-1-2505364}}</ref> Upon arrival at London King's Cross, driver Duddington and inspector Sid Jenkins were quoted as saying that they thought a speed of {{convert|130|mph|0|abbr=on}} would have been possible if the train did not need to slow for a set of junctions at Essendine. There was also a permanent speed restriction of {{convert|15|mph|0|abbr=on}} just north of Grantham station, which slowed the train as they sought to build up maximum speed for the descent of Stoke Bank.<ref>{{cite book |title=Speed on the East Coast Main Line |page=64 |first=P.W.B. |last=Semmens|year=1989|publisher=Patrick Stephens|isbn=978-0850599305}}</ref>

The A4 class previously had problems with the [[big end]] [[Bearing (mechanical)|bearing]] for the middle cylinder, so the big end was fitted with a "stink bomb" of [[aniseed]] oil which would be released if the bearing overheated. After attaining the record speed, the middle big end did overheat and the crew reduced speed, running at {{convert|70–75|mph|abbr=on}} onwards to Peterborough,<ref>{{cite web |url=https://www.railwaymuseum.org.uk/what-was-on/mallard-75 |title=Mallard 75 |publisher=Railway Museum UK|access-date=26 June 2018|date=2014|archive-url=https://web.archive.org/web/20180627034657/https://www.railwaymuseum.org.uk/what-was-on/mallard-75 |archive-date=27 June 2018 |url-status=live |df=dmy-all }}</ref> after which ''Mallard'' was sent to [[Doncaster Works]] for repair. This had been foreseen by the publicity department, who had many pictures taken for the press, in case ''Mallard'' did not make it back to Kings Cross. The (Edwardian period) [[GNR Class C1 (large boiler)|Ivatt Atlantic]] that replaced ''Mallard'' at Peterborough was only just in sight when the head of publicity started handing out the pictures.

[[File:Mallard Record Plate 01.jpg|thumb|upright|''Mallard''{{'}}s speed record plate]]
''Mallard'' topped Stoke Bank at {{convert|75|mph|0|abbr=on}} and accelerated downhill. The speeds at the end of each {{convert|1|mile|abbr=on}} from the summit were recorded as: {{convert|87.5|mph|abbr=on}}, {{convert|96.5|mph|abbr=on}}, {{convert|104|mph|abbr=on}}, {{convert|107|mph|abbr=on}}, {{convert|111.5|mph|abbr=on}}, {{convert|116|mph|abbr=on}} and {{convert|119|mph|abbr=on}}; half-mile (800&nbsp;m) readings after that gave 120{{fraction|3|4}}, 122{{fraction|1|2}}, 123, 124{{fraction|1|4}} and finally 125&nbsp;mph (194, 197, 198, 200 and 201&nbsp;km/h). <!-- would the speeds be better as a list? --> However, the dynamometer car tracks the current speed every half second on a paper roll moving {{convert|24|inch|abbr=on}} for every mile travelled. Speeds could be calculated by measuring the distance between the timing marks. Immediately after the run staff in the dynamometer car calculated the speed over five second intervals, finding a maximum of {{convert|125|mph|0|abbr=on}}. Although {{convert|126|mph|0|abbr=on}} was seen for a single second, Gresley would not accept this as a reliable measurement and {{convert|125|mph|abbr=on}} an hour was the figure published.

Gresley planned to have another attempt in September 1939, but this was prevented by the outbreak of World War II.<ref>{{Cite book |last1=Boddy |first1=M.G. |last2=Neve |first2=E. |last3=Yeadon |first3=W.B. |editor-last=Fry |editor-first=E.V. |title=Part 2A: Tender Engines – Classes A1 to A10 |series=Locomotives of the L.N.E.R. |date=April 1973 |publisher=[[Railway Correspondence and Travel Society|RCTS]] |location=Kenilworth |isbn=0-901115-25-8 }}</ref>{{rp|126}} In 1948, plaques proposed and designed by Harry Underwood, a headmaster and keen steam enthusiast, were fixed onto the locomotive which stated {{convert|126|mph|0|abbr=on}}, and this became the generally accepted speed.<ref>{{cite magazine|title=Harry Underwood|magazine=West Riding Small Locomotive Society|date=1948|quote=Harry Underwood is recorded as being the instigator of the idea (via the C.M.E.

====Rival claims====
''Mallard''{{'}}s record has never been officially exceeded by a steam locomotive, although a German [[DRG Class 05]] reached {{convert|124|mph|abbr=on}} in 1936 on a stretch of track that is flat, unlike Stoke Bank, which is slightly downhill. However, the Class 05 hauled a four-coach train of 197 tons, whereas ''Mallard''{{'}}s seven-coach train weighed 240 tons.<ref>{{cite video|url=https://www.bbc.co.uk/news/magazine-23137106|title=Magnificent Mallard: The world's fastest steam locomotive|time=02:49|date=2 July 2013|access-date=21 July 2018|archive-url=https://web.archive.org/web/20181226040741/https://www.bbc.co.uk/news/magazine-23137106|archive-date=26 December 2018|url-status=dead|df=dmy-all}}</ref>

Several speed claims are tied to the US [[Pennsylvania Railroad]] and their various [[duplex locomotive]] classes.

===1948 Locomotive Exchange Trials===
{{unreferenced section|date=June 2019}}
In 1948, shortly after the formation of [[British Rail]]ways, the decision was taken to test locomotives from all of the former 'Big Four' companies to find the best attributes of speed, power and efficiency with coal and water. There were two ways of testing and comparing locomotives: either at the [[Rugby Locomotive Testing Station]], which was not ready until late 1948, or by testing in the field. The results of the [[1948 Locomotive Exchange Trials]] would be used to help design the British Railways [[Steam locomotives of British Railways#BR Standard Classes|Standard]] locomotives.

The express passenger locomotive designs which would be compared were: [[London Midland Region of British Railways|London Midland Region]] (former [[London, Midland & Scottish Railway|LMS]]) [[LMS Princess Coronation Class|''Princess Coronation'' class]], [[Eastern Region of British Railways|Eastern Region]] (former [[London and North Eastern Railway|LNER]]) [[LNER Class A4|Class A4]], [[Southern Region of British Railways|Southern Region]] (former [[Southern Railway (England)|Southern]]) [[SR Merchant Navy Class|Merchant Navy class]] and [[Western Region of British Railways|Western Region]] (former [[Great Western Railway|GWR]]) [[GWR 6000 Class|King class]].
[[File:The 'World's Fastest Steam Locomotive' , 'Mallard' with a transitional number, at King's Cross in 1948 - 2283205.jpg|thumb|left|''Mallard'' with the number 'E22' during the Locomotive Exchange of 1948]]
Three Gresley A4 locomotives were chosen to represent the Eastern Region: E22 ''Mallard'', [[LNER Class A4 4902 Seagull|60033 ''Seagull'']] and [[LNER Class A4 60034 Lord Faringdon|60034 ''Lord Faringdon'']]. All of the locomotives had the Kylchap double blastpipe chimney arrangement and were fresh from Doncaster works. ''Mallard'' had emerged from Doncaster with a fresh coat of post-war garter blue livery, stainless steel numbers 22 with a small 'E' painted above them (for Eastern region), new boiler (its fourth), and third tender of its career.

E22 ''Mallard'' was used on 8 June 1948 on the [[London Waterloo railway station|London Waterloo]] to [[Exeter St Davids railway station|Exeter]] route. Driver Marrable took the famous A4 with a load of 481 tons tare, 505 tons full, the same that had been used on the previous trip by [[SR Merchant Navy Class|35018 British India Line]]. ''Mallard'' reached [[Clapham Junction railway station|Clapham Junction]] in 6 minutes 57 seconds and Woking in 28 minutes 47 seconds. At Hook there were adverse signals, causing ''Mallard'' to slow to a crawl. Even so, [[Salisbury railway station|Salisbury]] was reached in 108 minutes and 28 seconds. Despite the signals earlier, the train was only 5-and-a-half minutes late. The net time was 95.5 minutes.

''Mallard'' failed after this trial and 60033 ''Seagull'' took over. On 10 June ''Seagull'' achieved the run in 96 minutes 22 seconds, but had departed 3 minutes late, meaning ''Seagull'' had arrived with the same load 3.5 minutes early. ''Mallard'' returned to the Waterloo-Exeter line for a Locomotive Club of Great Britain (LCGB) railtour on 24 February 1963.

===The Elizabethan===
[[File:60022 080961 Darlington.jpg|thumb|upright|''Mallard'' hauling the ''[[Elizabethan Express]]'' in Darlington in 1961]]
The ''[[The Elizabethan|Elizabethan Express]]'' was a flagship express that ran non-stop over the {{convert|393|mi}} between [[London King's Cross railway station|London King's Cross]] and [[Edinburgh Waverley railway station|Edinburgh Waverley]] from 1953 to the mid-1960s. Until September 1961 it was steam-hauled. In its day it was the longest non-stop run in the world. Two crews were needed for the six-and-a-half-hour run. They were able to change over mid-journey by using a [[corridor tender]]. Only 22 locomotives including ''Mallard'' had such a tender. In December 1961, ''Mallard'' hauled the final steam-hauled northbound ''Elizabethan'' train.<ref name=hale/>{{rp|280}}

==Preservation==
Following the introduction of diesel and electric trains, many steam locomotives across the UK were set to be scrapped. In December 1960, a notification was issued to have ''Mallard'' preserved, confirmed on 29 August 1962. Its final revenue-earning service took place on 25 April 1963, after which the locomotive was sent to Doncaster Works for repair, and restored to its original condition.<ref name=hale/>{{rp|281–282}}

In February 1963, ''Mallard'' was sent to [[Nine Elms]] depot, followed by the Museum of British Transport in [[Clapham]], south London.<ref name=hale/>{{rp|82}}<ref>{{cite magazine|title=Mallard preserved|magazine=[[Railway Gazette International|Railway Gazette]]|date=1963-12-06|page=643}}</ref> It then ran a series of special trains, including a run from Doncaster via Nottingham Victoria to Clapham Junction.<ref name=hale/>{{rp|283}} Following a relaxation of the ban on steam locomotives in the UK in the 1970s, ''Mallard'' hauled a train from [[Stewarts Lane]], Battersea to York via the [[Midland Main Line]] in on 12 April 1975 in preparation for the opening of the [[National Railway Museum]], where it remained.<ref name=hale/>{{rp|283}} This was followed by periods on display at York Works in June 1977 and Doncaster Works in June 1978.<ref name=hale/>{{rp|284}} In the 1980s, ''Mallard'' was restored to working order to commemorate the 50th anniversary of its 1938 record speed run. Its first run took place on 26 March 1986 from York to Doncaster, and a series of other special trains were completed across England in 1986 to 1987.<ref name=hale/>{{rp|284}} The locomotive's final run in operation was on 3 July 1988 from Doncaster to Scarborough and back, which was attended by several family members of the original train crew on the 3 July 1938 run. The trip was related to a special ''Mallard'' commemorative postage stamp.<ref name=hale/>{{rp|285–286}}<ref>{{Cite web|url=https://www.collectgbstamps.co.uk/explore/issues/?issue=326|title = Transport and Communications|date=1988-05-10|publisher=Collect GB Stamps|access-date=2022-08-27}}</ref>

In July 2003, ''Mallard'' was put on display outside the National Railway Museum as part of the 150th anniversary of Doncaster Works.<ref name=hale/>{{rp|289}} It was taken outside again in July 2008 beside three other preserved A4s located in the UK, thus reuniting them for the first time since preservation.
