Campgrounds and Trains

[iis612]

I'm interested in campgrounds that have some sort of railroad interest. Please post.

I'll start with Port Huron KOA. I-69 West of Port Huron at Wadhams.
This used to have a railroad along one side and a pair of cabooses that were slowly disintegrating. The cabooses have disappeared and the railroad is now a bike trail.
However, they do have a 15" gauge park train that runs around on weekends. (4-2-4, gas engine).

I stayed there several times when I was a kid. I have some great memories of that place. I had a ball there. My Mom would not let me near the cabooses though.
