Interesting. Surprised UP hasn't sold the land off for development yet - though if there was a roundhouse there, there is certainly soil contamination of various unpleasant kinds to clean up.
Scrolling around, you can still follow much of the former SP line too. Ran around the east side of the yard. Guess Oroville isn't one of those places where every square inch is worth a fortune, yet.
Then move on up the line a bit to see what's become of the WP station - Yum!:
