Steam Locomotive Valve Gear

To most modelers and devotees of steam locomotives, the workings of the valve gear are a mystery. The clinic provides an understanding of the mechanics and mathematics involved in transforming the power of the boiler’s steam into mechanical motion. The clinic also focuses on the historical origins, evolutionary advancements, and spotting features of the different types of valve gear. It includes a key discussion of engineering and design terms most modelers would have no understanding of when looking at a builder’s specifications and schematics of a locomotive.
