About the Iron Duke class

Later called the Alma class, and giving rise to the spin-off Rover class, the Iron Duke class were some of the Broad gauge engines used on the Great Western Railway.

Once the successful Firefly class had been created, the Iron Duke was created as an prototype for improvement. Initially the only change was to increase the diameter of the driving wheels, but after an accident it was rebuilt in a 4-2-2 set up, with four wheels in front of the driving wheels. This proved successful and the class was built to this design.

The Iron Duke class was developed from the already successful Firefly class. The prototype was completed in 1846, and the rest of the class soon followed.

It looked very similar to the Firefly, the main external difference visible in images being the two wheels in front of the main motive driving wheel rather than one.

Other differences, such as the larger driving wheel, can be hard to make out in the pictures of the time without a direct comparison.

It pulled the Flying Dutchman, for some decades the world's fastest express. As this ran across the country, from London Paddington to Penzance in Cornwall, the Iron Duke engines became instantly recogniseable and iconic. Speeds of sixty miles an hour were common, but the Iron Duke was known to reach eighty.

The Iron Duke class, like most broad gauge engines, could not be converted to narrow gauge. When broad gauge was removed, the engines had no purpose, and the scrappers' yards were full of them.

The Iron Duke class engine "Lord of the Isles" was selected for preservation at Swindon. It outlived the broad gauge Great Western by less than ten years. In 1906 it was scrapped by the same order that saw the destruction of the North Star, the first broad gauge engine ever built which had also been preserved there.

The decision was condemned as short sighted at the time, and history has proved that point. Within twenty years a replica of the North Star had been built (using the original pieces where possible), and a more recent replica of the Iron Duke has been created.

A working replica

The Iron Duke

In 1985 a replica of the Iron Duke was constructed. Although it is fully working, and in fact ran on some of the few Broad gauge stretches at Didcot Railway Centre, it is currently not able to run due to expiry of the boiler certificate.

It is usually housed at the National Railway Museum in York. As well as Didcot, its other famous excursion was to the SS Great Britain in Bristol, where it was displayed alongside the historic Iron Ship for Brunel's jubilee.

Few images of the originals are available (consider when they were built and eventually scrapped). However, the replica that was constructed is available for public viewing and some photographers have kindly made their images available online through flickr.

Possessed of a walrus moustache, the Iron Duke replica featured briefly on the Thomas the Tank Engine series in the episode "Thomas and the Great Railway Show". Thomas took a trip to the York Railway Museum and discussed Broad Gauge and the vanished GWR with him.

The book is available through Amazon.com at a high price, but can be had from .co.uk at around $2, which makes it cheaper even with postage.

The Star Class were the first engines to run on the Great Western, quickly joined by the Firefly, Sir Daniel Gooch's design specifically for Broad Gauge.
