Ok, first....There is almost always one powered unit and one dummy unit. As in this case, the powered unit was in front, with the dummy (storage) unit in the back. They both have controls, but the dummy is basically a remote control unit.
Secondly, the whistling sound that is heard in the video is of the spring/shock system between each car. The talgo is equipped with a unique suspension system that tilts each wheel set in a turn or dip to provide comfort to the passengers.
@SeanicWind usually they have the NPCU on the north section of the train with the generator and first class cars, on the other end is the coaches and baggage car.
@SeanicWind Thanks for the interesting question. Actually, there isn't a front or back of this train. It has power on both ends. As for where the business cars are in the consist, I have no idea how Amtrak determines that. Maybe some of the other experts, like @skmexifry might chime in on this.
Hi, Thanks for watching and the interesting question. Don't know the answer, but I suspect it has something to do with the Talgo trains. I've heard this noise before on other Talgo trains, but never on the other types of Amtrak equipment. Maybe someone who knows will see this question and give us an answer.
@hotcore5312 The hissing sound is the path between each car basically expanding and contracting because all of the cars are conected and cant be uncoupled.
@jetwash999 Actually....the whistling noise is the leveling valves for the air suspension trying to compensate for the irregularities in the tracks. They keep the train level when it's not in a turn by releasing air out of the left or right towers. I'm an On-board tech on those trains, we get to listen to it all day!
This is great and I'll have to visit! If you get a chance to film at Carkeek Park standing directly above the tracks, it's a thrill. So many places to enjoy trains in the NW. JUST discovered a designated bike path from Sculpture Park, to side-by-side train track along Elliot, to Pier 91 in Magnolia~safe, beautiful, fun!
I saw one of your comments concerning mounting the flip video. Check out the smart pod channel to see a unique mounting accessory that attaches anywhere and everywhere, even in a car. Pls check it out. It's perfect for vlogging on the go. Thanks.

@hotcore5312 The brakes did not fully release, therefore the sound is the wheels rubbing the brakes. Then the brakes release, and it stops.
