At a time when it would have been so much cheaper in the 1960s, the Second+Narrows+Rail+Bridge and the Thornton_Tunnel should have been built wide enough to eventually accomodate 2 sets of tracks.
The New_Westminster Rail_Bridge should have been twinned a few generations ago. Really, a new 2-4 track bridge should have been built at least a few decades ago. https://en.wikipedia.org/wiki/New_Westminster_Bridge#Proposed_changes
