resulted in the locomotive riding on three cast steel "sub-frames" carrying the ten front-most spring brackets and lengthened spring brackets behind the rear driven axle. Perhaps remarkably, these were not integrated into a cast combined sub-frame/pony truck pivot stretcher, the pony truck pivot stretcher being a fabrication. Had the planned batch of further smaller Pacifics been built, they would have been fitted with this arrangement. Construction history The opportunity to create an entire batch of locomotives within the 8P category was declined by the Railway Executive. It had been said this was because the design process had been highly expensive and complex, so that when the locomotive emerged from Crewe Works in 1954, such thoughts were inappropriate, especially with the advent of the 1955 Modernisation Plan. As a result, 71000 remained the solitary member of a proposed class of Standard 8P locomotives. Naming the locomotive Upon emerging from Crewe Works in 1954, the locomotive was named Duke of Gloucester prior to entering revenue-earning service. Had further locomotives been constructed, they would have belonged to the Duke Class, standing alongside the sister locomotives of the Britannia and Clan Classes. Since then, the locomotive has colloquially been referred to by steam enthusiasts and crews as the Duke. Operational details The Duke was highly unpopular with crews, who regarded it as something of a liability due to its poor steam production. Inefficiencies caused by the problems regarding the draughting abilities and firebox design meant that no further examples were constructed. The fact that no effort was made to rectify these problems indicates the change in policy regarding steam locomotives, with the Modernisation Plan entering circulation as the "Duke" entered service. Based for its entire working life at Crewe North depot, the locomotive was utilised in hauling boat trains on the undemanding North Wales Coast Line between Crewe and Holyhead. All of this culminated in the locomotive having a short service life of only eight years, being withdrawn from service in 1962. The reputation of the locomotive amongst its crews as being a poor steamer was eventually to disappear – but only after it was rescued from the scrapyard during 1974. Livery and numbering The livery of the "Duke" was a continuation of the British Railways standard class practice. The class was given the power classification 8P. Following on from the 'Britannias', the "Duke" was numbered under the British Railways standard numbering system in
