If we are talking double-tracking from Portland to at least Sacramento, then the answer is
"No" as there are hundreds of miles where the ROW is not wide enough for an additional track.
I take Amtrak's
Coast Starlight from Los Angeles up to Portland or Seattle about once a year. It's a delightful way to travel if you get a room in the Sleeping Car and then have access to the First Class Lounge Car and the Dining Car. It takes two days to get there, instead of a two hour plane trip. From Eugene the tracks head east into the mountains, then southwest from Klamath Falls past Mount Shasta down to Redding.
The railroad tracks on that route traverse steep grades, many long tunnels, go over slim wooden bridges above roaring rivers, and thread through narrow mountain canyons and passes. That route is truly a marvel of early 20th century railroad engineering, but there is barely enough room for one train, let alone two.
If the current West Coast railroad routes were to be double-tracked between Eugene and the Bay Area, the costs would be in the Billions. Heck, the tracks that cross and hug the Willamette south of Oregon City are narrow and winding and would present a massive engineering challenge just to get another track to Salem.
