I have a Boeing rail car including the 737 body section, as a part of my O-Gauge train collection. One of only 200 Boeing rail cars made for train collectors. There are Boeing execs that would pay a small fortune for it. But its mine all mine. Of course I have a BNSF SD70 to pull it around during those rare times I let the Boeing car on the track
I saw 4 or 5 up close and personal at the Livingston, MT train depot one evening a couple of years back. I’ve heard that the car behind the fuselage carries the paperwork, but maybe it’s the tail?
