Princess Royal was first of the class of the same name. Designed by William Stanier they were Pacific locomotives and 12 were built in the early 1930s. They were used to haul the famous Royal Scot train between Euston and Glasgow Central. Two of the class are preserved.

They were the first Stanier ‘big’ engines and utilized best practice in locomotive design from various sources, particularly the Great Western. Although eclipsed later by the introduction of the enlarged Princess Coronation Class they continued to run on premier services until being phased out in the sixties.

Princess Royal measured 74’ 4.25” long and weighed in at 104.5 tons.

This fine model was shown at the Doncaster show in 2016 by Stuart Rothwell and was 11 years in the making to an H P Jackson design. Mr Jackson also produced a design for the streamlined Coronation class in 2.5” gauge. A Princess Royal design in 2.5” gauge was also produced by LBSC.
