I was in the right place at the right time yesterday and caught a brief glimpse of a couple of UP business cars.
I was on my way to the store out in the desert east of Southern California. The UP tracks parallel the I-10 freeway here. I was on a smaller road that winds in roughly the same direction and at a point where the road veers closer to the freeway with an open view. I caught a flash of yellow in the corner of my vision and looked over and saw a UP diesel pulling two UP business cars heading west. I was going around 50, and the train was moving along at a faster speed. I didn't get a very good look, and my train ID skills are pretty basic, but the aft car had an open platform and the forward car had an uneven arrangement of windows. Although they were probably different cars, it looked kind of like this photo I found on railpictures.net UP Train A fun treat when you are just going to the store.
