Thanks, everyone!
John, no fisheye lens, but just the wide end of my 18-105mm Nikkor, shot at 1/20th of a second. The lens has vibration reduction (VR) built-in, which definitely helps when you're trying to frame-up a shot while being jostled around in the north end of the caboose.
Mike, that sounds like a good one to me...the only one that popped into my head sounds more like a mafia nickname...Joey "the Rocket"

PS - notice how he's sneaking a glance over his shoulder...just making sure the train is still along for the ride!
