The triple expansion engine is a popular project for model engineers with time available. This example is by D Lidster and was shown at Doncaster in 2016. The triple expansion marine engine model designed by O.B. Bolton is one of the iconic designs of model engineering. Despite being a complex model, it has proved to be extremely popular, and nicely finished examples can fetch good prices for second-hand model dealers. The original design was revisited by John Bertinat in the mid 80s. Drawings, castings and instructions are readily available from a number of suppliers. Stuart Models also produce castings for their own, slightly smaller, triple.
