EspañolBR STANDARD CLASS 6
(Redirected from BR standard class 6)
The 'Standard class 6', otherwise known as the ' 'Clan' Class', was a class of 4-6-2 'Pacific' steam locomotive designed by Robert Riddles for use by British Railways. Ten examples were constructed between 1951 and 1952, with a further 15 earmarked for construction. However, due to acute steel shortages in Britain, the order was continually postponed until it was finally cancelled upon the publishing of the .
The 'Clans' were based upon the BR standard class 7 design, though incorporated a smaller boiler and various weight-saving measures in order to increase the route availability of a 'Pacific'-type locomotive for their intended area of operations, the west of Scotland. None survived into the preservation era. The 'Clans' received a mixed reception from crews, with those regularly operating the locomotives giving favourable reports as regards performance. However, trials in other areas of the British Railway network returned negative feedback, with complaints of the difficulty in steaming the locomotive and adhering to timetables being common.
The 'Clans' took their names from a previous class of locomotive that was being withdrawn from service at the time, indicating further their intended area of operations. The class was ultimately deemed a failure by British Railways, and the last was withdrawn in 1966. None survived into preservation, although a project to build the next locomotive in line, number 72010 ''Hengist'', is progressing on the East Somerset Railway.
The failure to create a satisfactory design for a 'Pacific' version of the Class 5MT 4-6-0 design spawned the further idea for a Standard Class 6 Pacific. This was due to the fact that the Standard Class 7 'Britannias' did not encompass a large route availability in Scotland due to exceeding weight restrictions, whilst the basic layout of a Standard Class 5MT did not lend itself well to further development into a 'Pacific', despite the obvious advantages in wider route availability.Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', p. 80 The solution of this problem came from the Southern Region, where the 'Bulleid Pacifics' were plying their trade. Oliver Bulleid, the chief mechanical engineer of the Southern Railway encountered a similar problem after the construction of his SR Merchant Navy Class in respect of a limited route availability because of the high axle loadings.Atkins, Philip: 'The enigma of the BR 'Clans' ' (''Steam World''), p. 6 As a result, he designed the Light Pacifics, smaller versions of the Merchant Navy Class that had the weight reductions necessary for them to roam the vast majority of the Southern Railway network.
The benefits of a design of smaller pacific further presented themselves in the success of Bulleid's 'West Country' Class No 34004 Yeovil during the BR Locomotive Exchange Trials of 1948. The data gathered from its use in Scotland greatly influenced the design of the new locomotive, as its specification and performance characteristics were highly similar.'A New Light Pacific' (''Trains Illustrated''), p. 82 The resultant design's utility was highlighted by the operating department's requirements for a more powerful locomotive than the 5MT types then in use, which was able to take larger trains to more diverse locations than could be reached by a 'Britannia'.Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', p. 85 Post-Second World War economics also played a part, as the brief stipulated the ability for the class to cope with the inferior quality of imported coal, thus necessitating the use of a wide firebox.
The arrangement consisted of a modified Standard Class 7 boiler, with smaller cylinders and other modifications to save weight and hence increase route availability. A wider firebox was also utilised to spread the weight evenly over the axles, whilst the standard smokebox completed the boiler, which at 225 lbf/in². was rated at a lower working pressure than that of the 'Britannias', A single chimney was incorporated into the design, although this was to create problems later on. Similarities with the 'Britannias' rested with the frames, tenders and running gear, allowing easy standardisation of parts common with other classes. The design was fitted with a standard set of two Walschaerts valve gear systems, and all members of the class were equipped with 4,200 gallon BR 1 tenders.
Designed at the drawing offices of Derby Works, the new class was constructed at British Railways' Crewe Works between 1951 and 1952.Cox, E. S.: ''British Railways Standard Locomotives'', p. 61 The initial order was for 25 locomotives to be constructed, but such was the immediacy of demand regarding a smaller version of the 'Britannias' that a batch of 10 was rushed through construction before teething problems had been ironed out at the British Railways testing station at Rugby. No more were ever built.
The choice of locomotive names came from E.S.Cox's desire to replicate the near extinct Ex-Highland Railway 4-6-0 'Clans', therefore representing Scotland in the new organisation.Cox, E. S.: ''British Railways Standard Locomotives'', p. 62 The first of the class. No. 72000 ''Clan Buchanan'' was treated to a special ceremony at Glasgow Central Station on January 15 1952 whereby the Lord Provost unveiled its nameplates. After initial running-in, E.S.Cox was quoted in discerning a distinct 'wooliness' in their steaming, and although they missed their appointment at the Rugby Testing Station due to late completion, some modifications were carried out, most notably to the diameter of the blastpipe, resulting in better steaming and increased power.Cox, E. S.: ''British Railways Standard Locomotives'', p. 64 Initially, the return cranks on the main driving wheels, were of LNER block-type as seen on Arthur Peppercorn's A1s and A2s, but this was changed to the simpler LMS four-stud fitting. Enough information was gathered through operational feedback from crews to allow a 'Mark 2' version to be planned, featuring modifications that would have created a better locomotive. This became known by its Crewe Works Order number, Lot 242.
The 'Clans' had a mixed reception when first introduced to British Railways locomotive crews due to the fact that there were only ten locomotives in a class that was mostly confined to the North West of the railway network.Atkins, Philip: 'The enigma of the BR 'Clans' ' (''Steam World''), pp. 6–7 The entire class was also based predominantly at two depots throughout their working lives, these being Glasgow Polmadie and Carlisle Kingmoor, compounding their restricted circulation. However, factors such as these meant that they spent most of their short careers out of the limelight that the 'Britannias' had, resulting in a relatively camera shy class of locomotive. Crews that used them on regular duties displayed their liking for the locomotives, and as such, could produce good work.Atkins, Philip: 'The enigma of the BR 'Clans' ' (''Steam World''), p. 10 However, the predominant number of crews who were unfamiliar with the 'Clans' found them difficult to handle, leading to an undeservedly bad reputation.
The poor steaming characteristics of the class had been the result of rushed production, which was another factor that led to the bad reputation of the 'Clans'.Farr, Keith: ' 'Clans' Highland and Lowland', pp. 722–723 Furthermore, they suffered from complaints regarding a lack of pulling power, although this can be attributed to indifferent handling and firing techniques, which certainly did not help the situation. However, had the Modernisation Plan been delayed, and the correct amount of investment made for undertaking the relevant modifications, such as streamlining of the steam passages and increased diameter blastpipe in a double-chimney layout, the 'Clans' would have been free-steaming workhorses worthy of complementing the 'Britannias'.Farr, Keith: ' 'Clans' Highland and Lowland', p. 718 Without modification, they were still capable machines when handled properly, as various feats testifying this included regular ascents of Shap and Beattock with 14 carriages without the assistance of a banking locomotive.Atkins, Philip: 'The enigma of the BR 'Clans' ' (''Steam World''), pp. 9–10 Other arduous duties that the class frequently undertook were the regular turns on the Settle to Carlisle route, which sports some of the steepest gradients and harshest working conditions of any British mainline. The Midland region was always short of top-link motive power and the 'Clans' proved to be a very welcome addition to the fleet.
The engines also performed on Glasgow-Crewe, Manchester and Liverpool services, Edinburgh-Leeds services, Carlisle-Bradford services, and finally the Stranraer Boat Train workings.Barnes, Robin: 'Salute to the Scottish standard - Part 2', pp. 286–287 As more crews got used to them, the class could be found far from home territory at destinations as diverse as Aberdeen, Inverness, Port Talbot, Newcastle upon Tyne, Bristol, and even London. 'Clan' number 72001 to this day remains the only Pacific locomotive to have worked over the West Highland Line, the result of a successful trial held in early 1956 to ascertain whether a Pacific type could traverse this steeply graded switchback line.Farr, Keith: ' 'Clans' Highland and Lowland', pp. 714–723 Having passed that test, a tribute to the versatility of the class, ''Clan Cameron'' was allowed to work special trains for the Clan Cameron gathering that took place in June of that year.Farr, Keith: ' 'Clans' Highland and Lowland', pp. 719–720
In August 1958, number 72009 was tested on the Eastern Region, being based at Stratford MPD, though a preference for the 'Britannias' meant that this sojourn was short-lived, lasting only a month. The locomotive was utilised on services from London Liverpool Street to Norwich, Clacton, and Harwich.'Experimental use of the Clan class on the Liverpool Street-Clacton service' (''Locomotive, Railway Carriage and Wagon Review''), p. 218 At first they were mistakenly allocated Class 7 duties, in which the 'Clans', although capable, were not able to keep to their allotted timings. This was part of the trials for the West Highland Line services mentioned earlier, but the locomotive was rejected for such duties on the grounds that they were 'no better than a good B1'. The result of these trials was that as both Class 7 and 8 locomotives were moved north in 1961 after dieselisation started in earnest, the 'Clans' were downgraded to secondary work. Maintenance was initially undertaken at Crewe Works, but responsibility was transferred to Cowlairs Works in the spring of 1958.Barnes, Robin: 'Salute to the Scottish Standard - Part 1', pp. 235–241 More varied work was allocated to them as their reliability improved, including working portions of the ''Thames-Clyde Express'' and the ''Queen of Scots Pullman''. They also deputised for the many failed diesel locomotives that plagued the network at the time, and were extensively used on freight workings.
Most Scottish and Midland region crews that used them regularly took to the class, and found that if used properly, running times were kept with ease.
These crews rated them the most surefooted of any 'Pacifics' available on the Midland Region, though other crews who tested them claimed that the 'Clans' were prone to slipping, though this was the case with most 'Pacific' designs.Barnes, Robin: 'Salute to the Scottish Standard - Part 2', pp. 288–290 Despite the various successes of the 'Clans', the class was generally regarded as a failure, even with overall performance being just short of Riddles' aims.Barnes, Robin: 'Salute to the Scottish Standard - Part 1', pp.236–237 However, the premise of all British Railways Standard designs was for a hard working, easily maintained, economical, highly available, and all-purpose locomotive. In these respects, the 'Clans' were highly successful.Barnes, Robin: 'Salute to the Scottish Standard - Part 2', p. 290
Prior to the publishing of the Modernisation Plan advocating the change-over to diesel traction, there was a proposal to construct a second batch of 'Clans', which was accepted as Crewe Works Order Lot 242. This authorised the construction of a further batch of fifteen 'Clans' that included modifications to the original design. Originally scheduled for 1952, due to acute steel shortages, the order was continually rescheduled until the publication of the British Railways Modernisation Plan finally halted the project. The initial name allocations for the new batch would seem to suggest several operating the Kent coast trains, hauling the Golden Arrow and other expresses, so that some of this batch would have been allocated to the Southern Region.'"CLANS" for the Southern' (Trains Illustrated), 406
The first locomotives to be withdrawn from service were the Polmadie locos 72000-72004 en masse in December 1962, where after being moved first to Glasgow Parkhead and stored, they were eventually moved to Darlington for scrapping in 1964. Of the Kingmoor allocation, the first, number 72005, was withdrawn in April 1965, whilst the final loco was 72008 on 21 May 1966 from Carlisle Kingmoor shed. When No 72008 ''Clan MacLeod'' was finally scrapped in August 1966, it rendered the class extinct. Though this locomotive served British Railways for only fourteen years and three months, it was the longest serving 'Clan.'Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', p.84
The livery of the 'Clans' was a continuation of the standard British Railways Brunswick green applied to express passenger locomotives after nationalisation. This was lined in orange and black, whilst the class was granted the power classification 6P.Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', pp. 82–83 Following on from the 'Britannias,' the 'Clans' were numbered under the British Railways standard numbering system in the 72xxx series.Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', p. 82 All of the locomotives were numbered between 72000 and 72009, and featured brass nameplates with a black background, located on the smoke deflectors, though towards the end of their working lives, some nameplates were painted with a red background.Clarke, David: ''Riddles Class 6/7 Standard Pacifics'', p. 84
None have survived, though a start has been made on constructing a new locomotive of the missing batch of 15, number 72010 ''Hengist.'' This is currently taking place at the East Somerset Railway, resulting in the locomotive potentially being the 1000th locomotive to be built to a British Railways standard design.Thomas, Cliff: 'The Lazarus locomotives: BR Standard Class 6' (''The Railway Magazine'': 2007, 1)
