I'll start it off with Donkey Engines, High leads & Heel booms, wheel car to repair broken down log skeletons cars. Blacksmith car & plenty of helpers on hand.
Lets see.........Shays and Mallets, spar poles with lots of high lead action, rickety bridges and a ramshackle camp, lots of creeks and gullies, and monstrous trees! Oh ya.......a log pond just like Shamus'!!!
Other than the obvious "EVERYTHING!!!" answer, I'll start off with my number one wish. Steam donkey info. I've asked about this before, but nowhere, does it seem, are there drawings of these.
Now, I know that they were usually put together in situ, but if anyone has rough dimensions, that would be great.
What I'm going to do is try to build one to fit onto an existing narrow-gauge flatcar, as I suppose that they'd have to be moved about at some point. (farther than just yarding themselves through the woods...site-to-site??)
