Mark,
Very interesting project. Looks like you just have something a little bigger than your Lionel trains to work on now! You even got Adriatic to come out of "lurker" mode. Good luck and looking forward to your updates.
Hope you can save what I assume is the original Milwaukee Road logo (the good one, at least).
Once you get it restored, what kind of options do you have in terms of where to run it?
Tom
