I apologize for the quality of the video, but
here is a video of a Capitol Corridor train on the Embarcadero, approaching OKJ from the north, taken on my recent trip.
Nice! Your video verifies what I was saying about the horn blasts through there (although I didn't see any pedestrians :blush: ).
Something else that should be noted for rail fans passing through there is the rail yard between OKJ and EMY. For a n/b train (like the OP's CS) shortly after re-entering dedicated ROW you will pass through a rail yard with a whole bunch of UP equipment on the left-side of the train and the Oakland Amtrak yard on the right-side. There will typically be a number of the California Amtrak cars/engines/train sets to be seen there and also (for the OP on the CS) the already turned-around CZ being made ready for the next day's run (assuming it isn't many hours late). Being at night though, much of this may be hard to see from anything other than a dimly lit bedroom.
