Trail of Tears State Park near Cape Girardeau, MO has some camping along the Mississippi. There are also railroad tracks by that campground too.
2x on the railroad track! It runs between the campground and the river about 100' behind the nearest campsite. And, there is a crossing ( meaning lots of horn toots) next to the campground. As long as you don't mind train traffic, no problems. Only a couple go through at night. Funny story - the campground host told me the trains don't bother him at all. He then mentioned that he takes out his hearing aids (both of them!)
It was also the first campsite I've been in that had GFCI protected 30 amp receptacles.
