About the Iron Duke class
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.

About the GWR "Iron Duke" Class
One of the earliest Broad gauge engines

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.

Pulled by the Iron Duke class of locomotives, the Flying Dutchman was for several decades one of the fastest trains in the world. The train between Paddington and Exeter, it could make the entire route in less than 5 hours, and did this twice a day. It was named after a racehorse of the time, who in turn was named after the ship.
It was also the last train to run on Broad gauge in 1892 before the switchover. The next day a narrow gauge engine ran the route, taking longer, and the train was simply the 9:15.
More about the Flying Dutchman from Wikipedia.
The Flying Dutchman was a named passenger train service from London Paddington to Exeter. It ran from 1849 until 1892, originally over the Great Western Railway (GWR) and then the Bristol and Exeter Railway. As the GWR expanded, the destination of the train changed to Plymouth and briefly to Penzance.
The end of the Iron Duke class
The Iron Duke class of Railway engines
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 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, and a more recent replica of the Iron Duke has been created.
Details from Wikipedia
The Great Western Railway Iron Duke Class 4-2-2 was a class of broad gauge steam locomotives for express passenger train work.

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.
