As an owner of vintage diesel locomotives we have been hit repeatedly (once even by another railfan group restoring a locomotive) by thieves. We have had a $5000 windshield smashed so they could gain access to one of engines. Even had a genius show up at a work session and ask if we were stripping the engine and could they please have the builder's plate. Sorry, stealing is stealing. BTW, if you're close enough to see it on the ground, you're trespassing already. Duck your head getting in the squad car so you look good in your mug shot.
