This meant that the boiler had to be raised considerably compared to other designs to allow the firebox to sit above the trailing driving wheels. As a result, the 9F features a distinctive void between the suspended boiler and the footplate. In operation the class proved extremely versatile. Not only did the 9F excel as a freight locomotive, but when required it also succeeded as a passenger locomotive. Reports even suggest that when 92220 ‘Evening Star’ was used to pull the Red Dragon express service between Cardiff and London it was forced to delay its arrival to allow the restaurant services to be completed, having outperformed the normal Britannia Class locomotives used on the service. This was not the only time 9Fs had been recorded outperforming dedicated express locomotives and on such services the locomotives were capable of running at over 90mph. This combination of high speed, fast acceleration and powerful hauling capabilities mean that many consider the class to be pinnacle of British steam locomotive design. Locomotive numbers 92165–92167 were built with a mechanical stoker. This system used a helical screw to move coal from the tender straight into the firebox. This meant that coal could be burnt a faster rate than a fireman could maintain otherwise. Systems like this proved extremely useful on long distance American railways however in Britain it was rare for a locomotive to require such as high rate of coal delivery over a long period of time meaning that a good fireman could prove just as effective.
