When I was an engineer at the Big South Fork Scenic Railway, I used to boondock at the shops. We were near the Norfolk Southern mainline where the line went from double to single track. Trains would sometimes back up at the signal and we'd oftentimes have some rather unsavory characters hop off of the trains. One night the alarm started going off on the locomotive shop and I was out there by myself. I was glad to have some protection but glad that I didn't have to use it. But I always kept it nearby just in case.
