I work as a contract engineer/inspector for a pipeline company and today I was down on the 8 heading east. Just before you get to Yuma there is a section of track all trains wait on to cross the Mission bridge in Yuma, well the second train in line had UP 1988 at the head of a 100 car consist of stack trains, and this one had a pusher at the end of it too. I sort of screwed up on one of the close ups when it was at the road crossing.
