GWR Iron Duke Class

GWR Iron Duke Class

The Great Western Railway Iron Duke Class 4-2-2 broad gauge steam locomotives for express passenger train work.

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. 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 [cite web

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 Although these locomotives took the names of withdrawn locomotives of the original design, they were not rebuilt from them like the first three, but entirely new locomotives (though it is believed that "Rover",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Apart from the three conversions, the original locomotives were withdrawn between December 1870 and June 1884. "Lord of the Isles" (the last to be withdrawn) was initially preserved by the GWR at Swindon Works, but was scrapped in January 1906 owing to pressure of space. The three conversions were withdrawn between September 1880 and October 1887, while the other locomotives to the later design were all withdrawn with the end of the GWR broad gauge in May 1892 (except "Hirondelle", which had been withdrawn in December 1890).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.

* "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.

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.
