Of course, the 12,000+ seat arena would need to go to make way for supporting uses. This kind of renovation would make a great architectural design competition.

Cascades high speed rail services already exists. The existing freight railroad ROW is owned privately; not by public agencies. Therefore, I don't expect they will ever upgrade their tracks higher than Class 5.
Here's the FRA track class speed limitations:
Sec. 213.9 Classes of track: operating speed limits.
(a) Except as provided in paragraph (b) of this section and
Secs. 213.57(b), 213.59(a), 213.113(a), and 213.137(b) and (c), the
following maximum allowable operating speeds apply--

As I understand the FRA rules:
Freight trains aren't allowed to go faster than 80 mph, therefore freight railroads aren't going to rebuild their tracks better than Class 5. It'll be a waste of their money to do so.
Therefore, the Talgo trainsets being used by Amtrak for the Cascades service are as fast and good as practical.
90 mph is pretty fast. The Talgo cars are capable of 110 mph, possibly up to 125 mph, in regular operations. But to go that fast, someone will have to pay to upgrade the track up to Class 7, and I guarantee that someone will not be the freight railroad companies.
