History
The prototype locomotive, Great Western, was built as a 2-2-2 locomotive in April 1846, but was soon converted to a 4-2-2 arrangement, with the leading wheels set rigidly within the sandwich framing, rather than in a separate bogie. The remainder of the class entered service between April 1847 and July 1855.
Locomotives of the Iron Duke class were extremely fast and had an estimated top speed of about 80 mph (133 km/h). They were used to haul the Flying Dutchman express train which, for several decades, was the world's fastest train. In 1852 the daily service from London Paddington Station to Exeter (194 miles) was achieved with an average speed of 53 mph (88 km/h); with the flatter section between London and Swindon covered at an average speed of 59 mph .
From about 1865, the Iron Duke Class was known as the Alma Class.
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 Although these locomotives took the names of withdrawn locomotives of the original design, they were not rebuilt from them like the first three, but entirely new locomotives (though it is believed that Rover,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Apart from the three conversions, the original locomotives were withdrawn between December 1870 and June 1884. Lord of the Isles (the last to be withdrawn) was initially preserved by the GWR at Swindon Works, but was scrapped in January 1906 owing to pressure of space. The three conversions were withdrawn between September 1880 and October 1887, while the other locomotives to the later design were all withdrawn with the end of the GWR broad gauge in May 1892 (except Hirondelle, which had been withdrawn in December 1890).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.

Famous quotes containing the word history:
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
“The history of mankind interests us only as it exhibits a steady gain of truth and right, in the incessant conflict which it records between the material and the moral nature.”
—Ralph Waldo Emerson (1803–1882)
“The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.”
—Gilbert Keith Chesterton (1874–1936)
