[Pannier tanks built for dockside working, such as pulling the Channel Islands boat express trains through the Weymouth streets. Later used in switching operations at Swindon. Retired 1961 (3) and 1964 (2).
See [Few countries used the 0-6-0 arrangements quite as heterogeneously as did Great Britain. Probably because of the high engineering standards that accompanied the construction of much of its right of way, a British railroad could more easily dispense with guiding lead bogies or trucks for light traffic. Hence, when it came time to replace Central Wales goods engines from decades earlier, Collett introduced these sturdy tender engines. Like all Great Western locomotives, these had Belpaire fireboxes.
The class was quite successful and the GWR added to it over the next 18 years. The scale-model locomotive supplier site [Data from E L Ahrons, The British Railway Locomotive, 1825-1925 (London: Locomotive Publishing Company, 1926), p 280.
William Dean freight engines with an unusual placement of axle springs outside and underhung. They were otherwise similar to the 1883 engines except for smaller grates. Ahrons commented that these were the last 0-6-0 engines with separate tenders to take shape around double frames.Data from Ernest L Ahrons, "The Early Great Western Standard Gauge Engines", The Locomotive Magazine, Volume 22 (15 February 1916), p. 23. Works numbers were 463-482 in 1864 and 581-590 in 1866.
By the time Joseph Armstrong moved from GWR's Wolverhampton Works to the still-bigger establishment at Swindon in 1864, standard gauge engines were the future of the railway. But the first locomotives to arrive were produced by this young, but already proven, builder. Ahrons pronounced the design "amongst the most handsome looking machines that ever ran on the Great Western ...the curves of the framing bore all the marks of Mr Beyer's design."

Pannier tanks built for auto-trains -- light passenger service in which the engine could be operated as a push-pull prime mover. The 6400s introduced the smaller, hill-climbing drivers and retained the Belpaire fireboxes. Retirements came in 1960 and lasted until 1964
See [Although identical in most respects to the 5400/6400 auto-train pannier tanks, this class operated conventionally on light passenger and freight service in Wales. Retirements came in 1960 and lasted until 1965.

This was the next step in the growth of the basic 0-6-0 design (Locobase 3219) then being built at Swindon. It had slightly more cylinder volume and weighed almost 4 tons more. These were soon followed by engines showing a sizable jump in heating surface area; see Locobase 10217.Data from "The BG Locomotives of the Great Western Ry", The Locomotive Magazine, Vol VII (April 1902), p.65.
Swindon now took greater advantage of the vast expanse offered by the 7' gauge to produce engines that were quite a bit bigger than similar locomotives on other British railways. Note that this class, which began with Giaour and came to include 25 other locomotives delivered in 1852-1854, had 2" tubes and quite a few of them. Even though the engine weight dropped slightly from the Druids (Locobase 10216), the maximum axle loading (on the middle axle, which took the connecting rod) increased. And more would follow: The Sixth Series, which came out of Swindon in 1854-1856, 36 locomotives that differed only in details from the Giaours. BP was now set at 120 psi. 1857-1863 in batches of 7, 33, and 12. Four additional locomotives (Juno, Iago, Plato, Bichon).were built as saddle tanks (0-6-0ST), but had very similar dimensions and areas.Data from "The BG Locomotives of the Great Western Ry", The Locomotive Magazine, Vol VI (December 1901), p.200. See also Glover (1967)
Daniel Gooch's classic freight design built with inside frames and had rounded and raised fireboxes. A later batch had a 54" diameter boiler holding 249 2" tubes and a grate area of 19.2 sq ft, which increased the free-gas ratio (total cross-section of tubes to grate area) to a still more impressive 28.29%. (Locobase wonders if that might have been too much of a good thing ...) As with the express engines, the 7-foot gauge allowed generous dimensions in both the boiler and the firebox.
