As for bypassing White Rock, never going to happen. Not enough people take the train out of Vancouver to make it worth spending lots of money to improve the travel time. I lived in Japan for several years and most people use the train since they don't own vehicles. Their population density also justifies having a super fast and efficient rail network.

The track splits 2 and 3 ways, but what are the typical conflicting moves? I'm going to go out on a limb and guess that most freight traffic is North Shore - Thornton Yard in Surrey CN traffic, while all but a few of the passenger trains are Pacific Central-Seattle. With two tracks, you can have a CN North Shore train on the east track and an Amtrak on the west track (provided that you double the northern approach, which is a single track segment of an otherwise double-tracked line) without one of them being in the other's way. Sure, SRY and Annacis traffic might still conflict, but you've got fewer potential conflicts to schedule around, and of course trains going the other direction

With respect to there not being enough traffic to justify upgrades, we are kind of in a 'let's not build a bridge because look how few people are swimming the river' situation with regard to the Amtrak Cascades north. That's not to say that White Rock is a worthy idea at this time, but merely that it's hard to make judgements about the value of investing in faster and more efficient service by looking at the current ridership of slow, inefficient service
