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.
Step 1: The displays
Bridge II., (I call: the wenge bridge) has maple and wenge wood base and laser cut wenge structure what I only nailed, except the top of the bridge where the tracks are, there I had to use some glue. The finishing is only tung oil, amplifying the beautiful color and the wood grains of the wenge.
Both bridges are capable to handle the Big Boy as the biggest loco. The wenge bridge has lighting separately switchable on both side of the display. Both can be used under analog or DCC (digital) mode, only need to plug the 2 track wires.
These bridges at this stage can not handle 3-rail system models, such as a Marklin. For that a little tweaking is necessary.

Let’s see the details...
