However that's a problem, because backwards BC can't seem to allow for proper long-range, bigcity infrastructure planning & development.

The Montreal Metro in the 1960s could run ridiculous 3 car trains, but eventually realized that 6 car trains & especially 9 car trains can efficiently more more people. Thus, its a good thing that they planned to have 152.4 m stations right from the start.
While short trains and stations can initially be a cost saving measure, allowing for future level clearance can be more economically efficient, in the long run. Thus, even a tram premetro can eventually be turned into a tram-train.
Unfortunatly, in typical Vancouver fashion, the Canada+Line wasn't designed to have 10 car trains, not even 5 car trains. The 2 billion dollar joke of a train was only designed with a level clearance for 50 m stations that only can accommodate a 2.5 car train. For a line that had to be open by 2009, it's still only running 2 car trains, with no 2.5 car trains in sight as 2025 is winding down.

Indeed, just because the Canada Line was designed as if it was only to start out with short premetro train stations, there should have been a long-term plan to eventually have proper big city trains. One of the biggest mistakes for what should be a proper big city metro train, is to design short stations that are almost impossible to double, let alone tripple in length.
