What about "beefing up" the railbed - an overpass here, a tunnel there - to allow for yet faster trains. They may not be HSR like the TGV or Shinkansen, but they'd exist.
The capital cost would possibly be considerably lower that for full-fledged HSR. If that works, attracting enough pax, then they could go go one step further upgrading to full HSR.
If not, at least there'd be a fast train, and who knows, it just might catch on, and become the preferred way to go. It seems to me that perhaps people are setting their initial goals too high.

The thing is, by far the largest issue to any speed for Amtrak Cascades north of the boarder (or likely anywhere) is the section of track that snakes along White Rock beach (from the boarder to Mud Bay). The only way to solve that problem is to reroute the line away from the beach to a new Right of Way (ROW) that is straighter and optimally in a sealed corridor (most likely along the 99). However, this could not be done incrementally and would be very expensive to do. If it is being done, the difference in relative cost for using Class V, VI or VII track would be minimal (though if shared with BNSF, there is little benefit for using anything greater than Class V). Given that the track would only be used by Amtrak and BNSF (both American companies) having Canadian governments fund it would be politically charged. The biggest counter argument is White Rock wants to get the tracks off of their beach, but I don't know how much weight that holds for the politicians.
Between Mud Bay and the Fraser River, it is largely a sealed corridor, so upgrades would be easy, but pointless unless speed can be found north or south of it.
Along the Fraser (both sides), it travels through rail yards and the train has to slow down for the bridge, so until the bridge is replaced, there is not much point increasing the speed. The bridge will most likely be replaced one day as it is used by multiple railways, so it is much more politically attractive. I would argue that doing so (even with track upgrades along the Fraser) will have minimal effect on travel times without upgrading the track further south as the train would have to slow right back down again.
The approach from New West to Pacific Central Station does have several level crossings that could be grade separated, but at that point the train is accelerating/decelerating for the station, so the speed benefit would be minimal, but should be done for safety reasons.
