I am a big fan of model trains but unfortunately I do not have a permanent room but what can I do if I already have a nice collection of trains especially steam engine models?
It is so nice to see the spinning wheels and moving rods. I was looking for a nice solution to display some of my collection and also run the engines. On the market there are a several products available for high price, with limited ways to place a large American steamer. So here comes again, I have to do something better and nicer myself. :)
The Broadway Limited came out once with a display bridge designed for the expensive brass Big Boy, but there were only fixed bearings and only for the Big Boy wheel arrangement. The basic idea was there I just needed to re-think and modify my display to serve different axis arrangements and have a nice look.
Lately I found this very interesting photo about a steamer dyno. So they actually existed in a kind of similar way as my design. Nothing new under the sky. :)
I already have plans to build a real loco dyno with measuring feature.
