Japan & Switzerland have great population density & excellent intercity train service. Just because Canada is a vast, underpopulated country, there should have been a long term, 4 track intercity linking plan. 6-8 tracks in the larger cities. Almost every major city eventually being connected with at least 1 freight track & 1 passenger track, each way. Plus, an east-west high-speed line to almost or sort-of compete with air travel.
What Canadian high speed rail could look like — if it ever happens https://www.youtube.com/watch?v=CXOKVIokp-Q
Even when the railroads were first built in Canada, there should have been 2 tracks on all the main lines. Thus, any bridge & tunnel should have been wide enough to immediately or gradually accomodate 2 sets of tracks.
The TCH has just been a 2 lane country road for most of its history, so far. At least its better than a waggon road. Of course in the cities, its more like a modern highway. https://tc.canada.ca/en/corporate-services/policies/trans-canada-highway-map
