1:12 scale model of London, Midland & Scottish Railway 4-6-2 locomotive "Princess Royal".

This is a model, made to scale 1:12, of the express steam locomotive Princess Royal.

William A. Stanier (1876-1965) joined the London, Midland and Scottish Railway Company in 1932 as chief mechanical engineer and immediately set about modernising the company's locomotive stock. The Princess class was introduced in the same year and could haul, unassisted, express trains of 500 tonnes the 400 miles between London and Glasgow. The LMSR, together with the other three British main-line railway companies, publicised and promoted their services extensively. This included the display of well-made models of locomotives and rolling stock at exhibitions around the country.

In 1936 they commissioned this model from the famous model-building firm of Bassett-Lowke Ltd. of Northampton. A slip of paper found inside it dated 3 July 1936 credits its construction to S. Borsberry and J. P. Nutsford.
