I thought this was a BNSF freight at first but it was a late Coast Starlight. I thought about it a minute and decided it worth driving the 40 miles to Steilacoom to get a better picture of a BNSF unit pulling Amtrak. A week earlier I saw a Cascade train being pushed by a UP unit. It may have been the train from Eugene, Oregon that starts in UP. It seems like I rarely have the camera when I see things like that.
