It sounds like an old Yakov Smirnov comedy routine, “In Russia, train photographs you,” but I was chasing a train on the Puget Sound & Pacific last night with another other local railfan. It turned out to be a DoD train heading to the sub base at Bangor. I know they were empties due to the lack of placards and how high the cars were riding on the trucks, but it didn’t stop whoever this was from poking his cell photo out from underneath a sheet of plastic (which was in every window of their hack) and getting a photo of me, getting a photo of them. It was poor light, didn’t get any really decent shots at all, but it was neat to see it as I’d never seen one of these trains before.

I'm a former Army officer and have seen all kinds of stuff I can't talk about, so I know how stuff like this works. I'm not the least bit concerned but a paranoid person would have probably been waiting for a knock at the door later...
That hack sure gets around: http://www.rrpicturearchives.net/rspicture.aspx?id=207578

Looks like someone on the hack might have been a bit "paranoid" too (and considering what they are responsible for, maybe they have reason to be). Still, I don't think they must enjoy the assignment very much; can you imagine how uncomfortable that caboose would be with plastic over all the windows like that? An air conditioner that's visible under the roof would help, but it still wouldn't be an enjoyable ride.

As it is, it is interesting to note some of the other special equipment visible in the photo. Besides the air conditioner, there's what looks like a loudspeaker, various antennae (including one that looks like a white gumball), and some spotlights at the corners of the cupola. Would be an interesting detailing project for a modeler.
