Those are some great shots of the really large scale trains, they build some nice equipment. Were those the 1 1/2" scale size? I was building an Allen Engines 2-6-0 but my twins came along and that pretty much sucked all the extra funds for building right out the window but it was worth it. Building one of those is an eye-opening experience, it's not just the cost of the locomotive, its the additional costs of the tooling you need to make it and all of the machinery you need also. It was also a good way to learn about metal working and machinist practices. I wish I still had my South Bend lathe, it was really a great machine. I still have my bench mill and all of the tooling for it. I'm setting it back up so we can use it at the lock shop where I work.
Thanks for the great pics.
