@gunrunnerjohn posted:I measured several of the Weaver and Williams brass that came through here, and some did have up to 44:1 gear ratios. With the motor screaming at 8,000 RPM, they were doing around 38 scale MPH. I never saw one with 72:1 gear ratio, that wouldn't have much of a top end I suspect!
Right you are, that looks like the ones I'm talking about.
Yes, the caveat being the die cast 2-8-0 that Weaver built with the integral gear box as part of the frame. That locomotive has a better gear ratio not quite as steep as we see in the brass engines……I wanna say the die cast 2-8-0’s are in the 20:1 ratio,…..but clearly the OP’s model is a brass engine, with a fully divorced gear box,…
