come to think of it, i think I've seen photos on Railpictures.net of LS&I RS-3s sitting on the Dead River Branch...I know i've seen them running under the ore dock.
BTW, this is actually in Marquette Right? I've seen enough old shots of the place to kinda sorta know where i am (in the 1950's probably...

it's the whole steam guy thing) but i'm having trouble transfering the track plan to my mental image (bearing in mind mine's probably all wrong anyway). I think a trip around google earth is in order.
Just saying, this route looks killer. If it's in a future version of trainz, I'd definitely buy it just to run this. though it needs about a dozen more 2-8-0s.
