Definitely be careful though! There’s plenty of rail that’s overgrown, horribly maintained, looks like it hasn’t been touched in 20 years but gets a train every few weeks or something. You’ll want to be very sure that it’s impossible for a train to be on the same track.
(There’s a town in my state that has some rail that is physically cut off from the railroad it used to be part of, so something like that would be the safest)
Or, if you’re more fun, a giant wall of lava lamps! The coolest randomness in town!
