Mike,
I looked at the footage again earlier this morning.
Its a Green Burlington baggage car, followed by a smooth(rounded)top silver coach, a clerestory silver coach, then 2 more smooth top coaches, that may not be alive, the second silver Clerestory roof coach, and the business car, green #96, with the Intermountain Chapter Drumhead on the rear.
Also the last shot shows the 638 runing around the train at a siding, and couples to the rear. On another track is a C&S switcher, so this must have been an industrial plant or mine or something, to require something stationed there.
The train seems to be in a low area with some hills and structures above the tracks nearby. Best I can describe it without sending it to you, which may be the way to go eventually.
Greg
