He has some advantage here: "Eureka" should be at least somewhat tolerant of marginal-quality (albeit, not outright terrible) wood because it has essentially an express engine firebox and boiler dimension given its 12x16 cylinders. Its heating surface is much greater than necessary for an engine of its size at normal narrow gauge railroad speeds. The 13x18 mogul later bought by the E&P had virtually the same heating surface, and Brooks produced 14x18 moguls that again had about the same heating surface. Case in point, soon enough 4-4-0 engines of the same pattern as "Eureka" (8-18C drawing 4) were being built with 12x18 cylinders (such as the "Jupiter" at the Smithsonian), and the later 12x16 engines (like the D&RG class 38) were being built with a boiler that had over 100 square feet less heating surface and they still ran fine at the speeds they were actually expected to operate at.
