Railfanning in Mukilteo, WA.

[Yard Limit]

The Sounder station at Mukilteo, Washington, is a great place to railfan!

You have some great videos on YT, but curiously I didn't see any taken along the nearby branch up to the Boeing plant. At ~4:00 in this vid the local is returning with some large fuselage size containers. Many of these originate at the Triumph Aerostructures plant (former Vought, former Northrop) here in Hawthorne, CA. on the El Segundo industrial lead; do not know where UP hands them off to BNSF.

Thanks for the comments. I think I would really have to be in the right place at the right time to catch it coming down from Boeing. I almost did this trip. Some of the containers they bring down from the plant, or back up to the factory, come off a barge just north or where I was. I've seen them use an overhead crane to load and unload the flatcars. That's pretty cool.
