The ‘Princess Royals’ were one of the first LMS designs produced during Stanier’s regime. Initially they suffered from a number of “teething” problems, some of them caused by ideas that Stanier had brought with him from the GWR, and solutions to these were developed over time. This resulted in twelve locomotives exhibiting numerous detail differences, with boilers and fittings, fireboxes, frames, pony trucks, cylinders, motion and tenders all widely varying both as built and due to subsequent alterations.

Our kit contains etched parts to build a model of the engines when fitted with the most common boiler type, the long firebox version which had a sloping throatplate and combustion chamber. In particular, it enables the first two engines, Nos. 46200 and 46201 which had GWR pattern slidebars, to be modelled, as well as the ten production series engines, Nos. (4)6203 - (4)6212. Note that the additional parts to produce the modified motion bracket etc for (4)6205 are not included in the kit.
