[edit] History
The prototype locomotive, Great Western, was built as a 2-2-2 locomotive in April 1846, but soon converted to 4-2-2 arrangement. The remainder of the class entered service between April 1847 and July 1855.
The Iron Duke class were able to haul express trains with high speed. The top speed was ca 80 mph = ca 133 km/h. The Iron Duke operated express train Flying Dutchman was the fastest train of the world in the middle of the 19th century. In 1852 this train made a daily service from London Paddington Station to Exeter (194 miles) with an average speed of 53 mph (88 km/h). The flatter part between London and Swindon had been absolved with an average speed of 59 mph [1].
In May to July 1870, three locomotives (Great Britain, Prometheus and Estaffete) were extensively rebuilt with new frames and boilers, but retaining their original names. Following these, further locomotives were built to similar specifications, entering service between August 1871 and July 1888. These new locomotives are generally referred to as the Rover class. Although these locomotives took the names of withdrawn locomotives of the original design, they were not rebuilt from them like the first three, but entirely new locomotives (though it is believed that Rover, Swallow and Balaklava may have included some parts from the earlier locomotives of those names).
Apart from the three conversions, the original locomotives were withdrawn between December 1870 and June 1884. Lord of the Isles (the last to be withdrawn) was initially preserved by the GWR at Swindon Works, but was scrapped in January 1906 owing to pressure of space. The three conversions were withdrawn between September 1880 and October 1887, while the other locomotives to the later design were all withdrawn with the end of the GWR broad gauge in May 1892 (except Hirondelle, which had been withdrawn in December 1890).
Many of the nameplates can be seen at the National Railway Museum and at Swindon Steam Railway Museum, while the driving wheels from Lord of the Isles can also be seen at Swindon.

- Great Western (1846 - 1846)
- Great Western, named after the railway, was designed to show how the 2-2-2 express engines could be improved; the eight feet diameter driving wheels being a foot larger than those of the successful Fire Fly class.
- It broke its leading axle after a short while in service and was subsequently rebuilt as a 4-2-2, becoming part of the Iron Duke class.

[edit] Replica
In 1985 a working replica of Iron Duke was constructed using parts from two Hunslet Austerity tanks as part of the Great Western 150 celebrations. The boiler certificate has expired so it cannot currently be steamed.
It is normally housed at the National Railway Museum at York, although it has also visited the Didcot Railway Centre, which has a section of broad gauge track. In 2006 it has been moved to Bristol where it is the centrepiece of the Nine Lives of Isambard Kingdom Brunel exhibition in the Maritime Heritage Centre adjacent to the SS Great Britain.
The replica appeared in The Railway Series book Thomas and the Great Railway Show, in which it was portrayed with whiskery eyebrows and a walrus moustache.
