The 2027 picture adjacent, with its tanks removed in 1957, shows the chimney is seated conventionally on the smokebox. Its tripcock gear is behind the step, and is clipped up into the raised position. Note how slender the rods are. 1042 fitted with a later standard 3-segment tank. A variation was the 1661 class 'production line' conversions of 40 2361 class 0-6-0 tender engines in 1886. Drawings are approximately redrawn from Russell but are strictly representative and may contain errors. The other pannier tank classes built by the GWR in the 20th century were the very small and light 1366 class and the very substantial 15xx. 1599 is in its last days, at Swindon, 28 June 1936. Middle batches had O or Q class boilers and some of the last batches a shorter boiler, which was closer to the P class. segment tank. By 1878 they were being turned out with open cabs and short cab roofs. From 1902 the last batches were built with a Belpaire firebox and a domeless boiler, but still with saddle tanks. The larger capacity boiler and increased adhesive (= braking) weight gave the 9400s capabilities that the 5700 class lacked. 2742, with polished boiler fittings, possibly at Exeter. Class 850 of the Great Western Railway was an extensive class of small 0-6-0 saddle tank locomotives designed by George Armstrong and built at the Wolverhampton Works of the Great Western Railway between 1874 and 1895. The rectangular shape adjacent to the chimney is the 'lubricator and blower pipe cover', which allows the pipes from the cab to come from under the boiler lagging, around and into the smokebox. 755, of the initial 727 class with a shorter saddle tank, in very early condition, with a rear weathershield fitted. Brake rods on the Wolverhampton small tanks were behind the wheels. All but 11 of the 1016 were eventually fitted with pannier tanks. It was allocated to Didcot at the time, and fitted with a spark-arrester ('busby') for working the Didcot Ordinance Depot. In February 1930, he took 2080, an autofitted 2021 class loco, fitted a larger (Standard 11) boiler and rewheeled it with 5'2" wheels to create a faster and more powerful locomotive. Some of the class ran on the Broad gauge for a while, which necessitated the wheels being outside the now inside frames. A very clean 5410 at Southall, in BR lined green, 6409 in early days, with footplate-mounted lubricator. 1051 in near-original condition with a short saddle tank of five unequal segments. A dozen Buffalos were fitted with P class boilers and large (1200g) tanks between 1925 and 1930. Home made Video made up from short clips filmed by my digital camera spliced together of a Alan Gibson GWR Class 850 Tank Engine. They first received Belpaire Q class boilers from 1911 and then P class from 1922. A batch of new engines, the 25 members of the 5400 class, followed from 1931/2 with the last batch in 1935. The original boilers were similar to but smaller in diameter than the Q class. Files are available under licenses specified on their description page. 907, of the 1854/1701 class, with an enclosed cab. Photo from FreeFoto.com, and licensed for reuse under. Pictured probably pre-WWI. 1080 received pannier tanks in 1927, and is seen here at Tyseley in 1929. For hillier territory the 5'2" wheels were too large, so another 2021 class loco (thought to be 2062) was rebuilt, this time with the 4'7½" wheels of the larger tanks. GWR 850 Class class of 170 British 0-6-0ST locomotives. The entire wiki with photo and video galleries for each article Main Wikipedia article: GWR 850 Class. 7409 at an unknown location in early BR days. None of the Collett/Hawksworth pannier tank classes, with the exception of the ten GWR-built 94s, were superheated. A common bunker style would not be established until the early Collett era, although many of the earlier locos would be scrapped before receiving Collett bunkers. These can be distinguished from the Q class boilered locos by their boiler tops being proud of the tank tops, the Q class boiler locos being 'flat-tops'. Although a few Buffalos had been autofitted from 1915, there was a specific programme starting in the mid-1920s, intended primarily for locos working in the Plymouth area, which involved fitting screw reverse. The saddle tanks were 1080g capacity, and the later pannier tanks were 1095g. Many 5700 locomotives also had their original style cab handrails altered to the style on the 8750 class. Topfeeds were fitted to the boilers from WWII onward. They had many detail improvements in design and construction, and could run much greater distances between overhauls than their predecessors.

The lubricator pipe cover at the cab end on the right-hand side, on 7714. Vind een Claas axion-850 Landbouw tractor te koop op Agriaffaires. 772, of the 645 class, in near original condition with Wolverhampton rolltop tapered chimney, original lamp sockets and full lining. It was rebuilt with pannier tanks in 1918. They were mostly scrapped in the 1920s and early 1930s, with the last survivor (1047) going in summer 1935. The 6' rear overhang was continued with subsequent lots of short saddle tanks (locos 1134–1153 and 1166–1185), whilst the remainder of the class had 6'9" rear overhangs. The first inside-framed Swindon class was the 1813 class of 1882–84. On flat-top panniers, the chimney base was set into a circular aperture in the top plate. 9417 also illustrates the position of the rear steps, attached to the side hanging plate. 307, one of the small number (eight) of the 302 class, receiving attention at Swindon on 11 September 1927.

Unusually for a Buffalo, the loco has acquired a set of Collett parallel-body buffers. Image courtesy of Kevin Dare. The worksplate is on the bunker side. It was fitted with pannier tanks in 1914. Many but not all were given enclosed cabs. Thus a locomotive might be rebuilt with pannier tanks at one major overhaul, yet revert to saddle tanks at the next one, depending on what was available. As with the 5700 class Collett had to develop replacements for older locomotives reaching the end of their lifespan. Some of these were fitted with condensing apparatus for use on the Metropolitan & District underground lines in London, and curiously these were never fitted with cabs. Early (side tank and saddle tank) locos had low coal capacities, but increased frame length and bunker capacities began to feature at a very early (c 1870) stage. Through Churchward's time, and going on into Collett's, the earlier large tanks tended to receive larger boilers, mainly Q and then P units. 655 class with enclosed cab and extended bunker, This sketch attempts to reconstruct the as built appearance of the 1813 class. All were fitted with ATC, steam heating and vacuum brakes from new, except 6750–79 (built from 1947 to 1950), which were 'shunting locos' fitted with steam brakes and three link couplings only, and thus were effectively an 8750 version of the 6700 subclass. When a major overhaul was due the GWR would dismantle a locomotive virtually down to its component parts 5. No toolbox is apparent, and the injector is of an early form in a forward position. These locos were significantly wider (tanks, cab, bunker), at 8', compared to the 7'5" body width of other Buffalos, and they had 8'6"-wide footplates. The GWR Class 800’s are very nice trains and are now in passenger service. It also illustrates how inconvenient the rear sandboxes were on many GWR tank engines. Of the smaller classes, the 2021 was most often autofitted, and 655 and 1076/1134 amongst the large wheel classes, but odd ones and twos of 1901, 1501 and 1016 classes received the gear from time to time. The pre-grouping classes appear to exist in quite mind-numbing complexity and variety. GWR K14-15; GWR 850; Weathered coaches by Martyn Welch; Update; SECR D class almost sold out! When thicker tyres were used they increased in diameter to 4'1½". The loco still has its original length tanks at this time. The locos included: 738, 1167/8, 1234/5/52/65/9/71/84, 1567/70/1600. GWR 850 Class, 978-613-6-96769-1, Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. (2080 reverted to 4'1½" wheels in April 1931.) It received pannier tanks in December 1926. This squarer shape was also carried by the other 15xx and 16xx Hawksworth pannier classes. The boiler feed pipes go in this space. The loco chassis had 4'1½" wheels and were the same as the 850 class. About half got enclosed cabs and/or enlarged fireboxes. Apart from the main difference in cab styles between the 5700 and 8750 classes, the other detail differences were in cab handrails, brake hangers, tankfront steps and injector routing. Over the years the earlier boiler classes went out of use (no new Standard Goods Sir Daniel or Metro boilers were built after the 1920s for instance) and so the amount of variation tended to reduce. 2704, of the 655 class, in near original (1895) condition, with a five (and a bit!) The 1366 was an updated version of the 1361 saddle tank class, itself an update of an engine used on the Cornwall Minerals Railway 19. There are two steps and two upper handrails on each side of the tank. These had wheel spacing of 7'4" (leading) and 8'2", and wheels that started at 4'6" but were later fitted with thicker tyres to 4'7½".
