What I found to be a problem with their photoshoot is that they choose to pose for pictures on the BNSF railroad tracks, and even posed on the diesel locomotive that is parked next to the depot.
Somehow, I doubt they cleared this with BNSF beforehand. I know at least one member of the local model railroad club will have a field day. Basically, it comes down to this: Trespassing on railroad property is dangerous and could get you in trouble with the local or railroad police. Unless a locomotive is on public display, it should not be used as a prop.
I’ll probably encourage Van Go to bring out a Operation Lifesaver representative to have a “discussion” with their students.
