I have had a serious set-back in the design of the Fairbank, AZ module. I have gotten totally immersed in the whole endo-skeleton idea discussed in The Origin of Portable Model Railroads: Or the Preservation of Favoured Techniques in the Struggle for Acceptance. The reason is that this also kind of supports the ideas in Something a Little Different.
Building a spine for a flat piece of track is one thing but the Fairbank module is, at least currently, supposed to be primarily a truss bridge over a river. This is going to call for a very different kind of spine that I have not even begun to figure out. Any ideas?
