Editing LMS Princess Royal Class (section)

==Overview==
The designer of the class, [[William Stanier]], had previously been Works Manager of the [[Great Western Railway]]'s depot at [[Swindon Works]], and had been recruited with a brief to replace the LMS's miscellany of locomotives inherited from its constituent companies. He made extensive use of Great Western features in his designs.

To match the power and speed and especially the prestige of the [[London and North Eastern Railway]]'s express Pacific locomotives, Stanier designed the Princess Royal class almost as soon as he was appointed to the LMS. When originally built, they were used to haul the famous ''[[Royal Scot (train)|Royal Scot]]'' train between [[London Euston railway station|London Euston]] and [[Glasgow Central railway station|Glasgow Central]].
