UP 3921
Title:  UP 3921
Description:  Westbound manifest heading through Arlington, at West Garrett, or about MP 230 on the UP Dallas Sub, which consisted of 11 (count 'em) engines. I just kept shooting until I saw part of the consist. I was so amazed at the amount of engines, that I originally thought this was a light engine transfer. This is my personal best for amount of engines on one train (not including light engine transfers).

Lucky rear-end DPUs
Title:  Lucky rear-end DPUs
Description:  Austin and waited all afternoon for a southbound freight to get this shot, with no luck at all. Every southbound either turned and headed for the Fallbridge Sub., or was an Amtrak. This UP northbound stacker came by with rear end DPU's and actually stopped at Vancouver North, with the DPU's setting nicely under the signal bridge. Not a southbound, but the next best thing.
