Every once in awhile, the old Pentrex videos covering the Blue Mountains pops up on Youtube. Some of the mopes who post them add various intros and such to outsmart the algorithms.
But the series of 2 videos, one covering Hinkle-LaGrande and the other LaGrande-Huntington was taped right when the C40-8Ws were new, but still restricted to trailing-only because of a problem with the new GE desktop control stand. Back then, no ditch lights and only roof strobes. Also gives a great look at the freight cars of the day, including the still-segregated single shipper stack trans for K-Line, APL and Maersk. The U30Cs and straight SD40s era is in their final throws.
Only the eastern segment LaGrande to Huntingdon seems to be on YT right now
