https://www.youtube.com/watch?v=a1ouk0VifwM&t=42s Even if the YVR-Canada Line had to initially be built as a symbolically small city train, urban transportation infrastructure can be designed in ways that can double or even triple capacity to meet future demand. Unfortunately, its very difficult to build anything in BC with significant future capacity in mind.
Ultimately, the YVR-Canada Line should have had level station clearances to eventually be able to accommodate 10 car trains. Unfortunately, in typical backwards BC planning the stations weren't even designed with enough level clearance to accommodate 5 car trains. The joke that is the Canada Line only has a level station clearance of 50m to eventually accommodate just a 2.5 car train.
Most other cities actually build long stations to accommodate long trains right in the first place. Or, at least allow for enough level clearance so that the stations can eventually be doubled or tripled in length.
The YVR-Canada Line should have started with the Vancouver & Richmond segment, then the Vancouver and Horseshoe+Bay+ferry+terminal segment. Then finally, the YVR to Delta and the Tsawwassen+ferry+terminal.

Unfortunately, proper big city transportation planning is very difficult to achieve in backwards BC. So much is watered down in Vancouver.
Montreal’s Biggest REM Expansion Yet https://www.youtube.com/watch?v=4G1oeIAfxDU&t=106s
The Montreal REM https://www.youtube.com/watch?v=g9O6RzsXIqQ
While the REM was designed to help the Metro, it should have the capability to be gradually expanded. Eventually, REM trains should be lengthened from 4 car trains to 6 and even 8 car trains.
In contrast, every Skytrain line should have been designed with enough level future station clearance to eventually accommodate a train as long as a 152.5 (500 ft.) long Montreal Metro train. The first 2 Skytrain lines have 80m stations and the joke that is the Canada Line only has 50m stations.
While the first 2 lines can accommodate 5 car trains, the C Line wasn't designed to accommodate 5 car trains. Just 2.5 car trains, someday.
Despite there being such a symbolic push for Vancouver to keep having short trains, narrow bridges and stumpy buildings, things are gradually changing in backwards BC. The Vancouver or BC Mind Virus should have been challenged decades ago, but too many loud people wanted to perpetuate the, KEEP THINGS SMALL AND INDEQUATE agenda.
Given how most of the bridges in Greater Vancouver are so narrow, there isn't enough room for proper bus and HOV lanes, or even wide emergency lanes. One would think that at least the trains & stations would have been designed to eventually be doubled or tripled in length. But that would go against the mutigenerational congestive planning agenda. That's why there still is only a 3 lane LGB when there should have been at least a parallel bus, HOV and train tunnel. The Pattullo+Bridge replacement didn't open with 2 bus and 2 HOV lanes, not even wide shoulders or emergency lanes. NW really likes the congestive planning approach. Of course the new tunnel between Richmond and Delta won't have an additional provision for a train tube. This will also help to perpetuate the congestive transportation mandate.
Fortunately, Selective_door_operation technology can eventually allow more sensible transportation planners to enable longer trains.

This means that a 5 car Skytrain (85m) could eventually become a 7 car train, despite the 80m stations.
https://en.wikipedia.org/wiki/SkyTrain_(Vancouver)_rolling_stock#Alstom_Mark_V Thus, an 80m train can become a 117m train.
A two car and 2.5 car (50m) train on the multibillion dollar Canada Line is so absurd and inept! With some slight station modifications, there could be a potential to eventually accommodate three, 20m cars at such short platforms. Then, once 3 car trains could become possible, its just a matter of having an extra 20m car at both ends of each train. A 5 car train of 100m is so much better than a 50m joke of a train.
