William Dean locos of the GWR : Great Western Railway GWR 4100 Atbara+Flower Class 4-4-0


The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom.
The Badminton class express passenger 4-4-0 steam locomotives were introduced in 1897 as a development from the earlier Duke class. The name Badminton was chosen after the Duke of Beaufort's Badminton estate, through which the GWR was building a new line to South Wales at the time.[1]
Further modifications to the design resulted in the Atbara Class entering service in 1900, the names for these locomotives generally being taken from contemporary military engagements or senior army commanders. Later engines were named after cities of the British Empire.
The final batch of locomotives were named after varieties of garden plant and in consequence were known as the Flower Class.
These three types were later standardised and treated as a single class, so are listed together here. Four other prototype 4-4-0s, originally built in 1894 as the Armstrong Class, were also later rebuilt as Badmintons (see below).
This class were subject to the 1912 renumbering of GWR 4-4-0 locomotives, which saw the Bulldog Class gathered together in the series 3300-3455, and other types renumbered out of that series. This class took numbers 4100-4172 (of which numbers 4101-4120 had previously been used by Flower Class locomotives).



3297 Earl Cawdor This locomotive of the Badminton Class was rebuilt with an experimental boiler. With the impending opening of the direct Reading-Taunton route which was of more undulating nature than the route via Bristol, there was a need to ensure that the most appropriate locomotives were provided. Churchward's Chief Assistant, F.G. Wright, designed a large boiler with a very deep firebox, which was fitted to no. 3297 Earl Cawdor in July 1903.[13] The boiler was designed to hold a large volume of hot water, forming a reservoir to assist the locomotive running along an undulating line.[14] It also provided a steam space of 85.13 cu ft (2.411 m3) as against the 76.2 cu ft (2.16 m3) of the Standard No. 4 boiler, the larger of the two types of standard boiler fitted to the 4-4-0s.[15][16] This increase in volume was intended to provide a reservoir of steam.[16] The firebox was set deep between the coupled axles, with a horizontal grate.[14] The intention with this was to allow a thick fire to be built up, increasing the area of the firebox in contact with the fire, and decreasing the temperature gradient along the firebox plates, thus reducing the risk of broken firebox stays.[13] The boiler was pressed to 210 lbf/in2 (1.4 MPa).[16] No. 3297 was also fitted with a large cab with two side windows, reminiscent of North Eastern practice.[16][17] The locomotive was regularly rostered on the most demanding trains, but it soon became apparent that it was not up to the work demanded and it was relegated to secondary duties. In October 1906 the boiler was removed and replaced by a Standard No.4 boiler, the North Eastern style side-window cab having been replaced by a Churchward type in November 1904.[17
