Why this kit matters
The Caprotti-fitted Black 5 locomotives represent an experimental phase in British steam development, where alternative valve gear systems were tested to improve efficiency and performance. No. 44748 is one of the most well-known examples, combining the proven Black 5 design with advanced Italian Caprotti valve gear technology.
This variation highlights British Railways’ efforts in the 1950s to extend steam viability through engineering innovation during the early diesel transition era.
How to use it
Place the locomotive and tender on powered OO gauge track and operate using DC or DCC control systems if fitted. Suitable for mixed traffic duties including passenger services, freight trains, and express relief workings.This is a detailed scale model intended for collectors. It is not a toy and is recommended for ages 14 and above.
