Here's something to consider. At least UP will continue to upgrade the Sunset Route. See link:

It looks as if UP will continue to delay and delay the Sunset & the Coast Starlight both, until the upgrades are all finished sometime this century. Funny how BNSF has the attitude where it will get Amtrak trains over the rails with punctuality, and collect the various incentive payments, just becuase they want to get Amtrak trains out of the way of the more profitable freights, while UP's solution to the same dillemma is to stall and sidetrack the trains, even though they have as busy a route to traverse as anything BNSF has (the Transcon via AZ, NM, and the Northern Transcon from St. Paul to SEA). BNSF despite all of their faults, get Amtrak over their rails in a timely fashion, while UP creates the impression that they can't get anything (including Amtrak) anywhere in a punctual fashion.
As I have posited elsewhere in the ether, I think UP detests Amtrak becuase Amtrak has a unique way of placing all of UP's operational flaws on public display.
