Mark, I for one would LOVE to see how you built these, if you had plans made up, and how well it works.
Thanks. It's a pretty basic build. I took it over to my brothers to let the nieces and nephews run some diagnostics on it. It's about 150% larger than standard brio height/width, so that rules out tunnels/bridges, and the length eliminates inclines, but it will run the larger curves just fine and I might be able to adjust it for smaller curves!
Sure does. Alco didn't pivot the rear engine. Mark may have developed the answer to many steep heavily loaded logging roads...if any still existed.
There's a guy from Facebook that is asking for an AC-12. Is that you? I'm just about ready to take custom orders.
