https://dailyhive.com/vancouver/mark-v-skytrain-design-translink When so many cities planned for 8-10 car trains, Vancouver can only max out with 5 car trains. Its always better to build longer stations & wider bridges in the first place.

Apparently, short trains and narrow roads are the best way for Vancouver to deal with its transportation congestion. Of course since most cities don't take a small scale planing approach like Vancouver does, they are able to have larger underground stations that allow for longer trains, wider bridges that make it easier to have bus & HOV lanes.
https://dailyhive.com/vancouver/canada-line-skytrain This is so sad & pathetic for backward BC. Clearly, this was built in symbolic defiance of the 152.5m or 500ft. long stations that the Toronto Subway & the Montreal Metro have. Instead of building all of the Canada Line with 152.5m long stations, the C Line was only designed to have 50m or 164ft. stations. This is classic Vancouver & BC inept logic at its best. Instead of running a 152.5m Montreal metro train every 5 minutes, a short BC train could be run 3 times every 6 minutes. Considering that Vancouver opted to not ever have a freeway to the airport & ferry terminal, a provision for a 500ft long train should have been made, right from the start.

Unlike Montreal, Toronto, Edmonton, Calgary & Seattle, Vancouver has been under a multi-generational small town mindset. Short trains & short buildings, narrow bridges & narrow roads, etc., are all indicative of a, KEEP THEM OUT agenda. If you plan & build big city infrastructure, you are indicating that you accept substantial urban population growth & density. Extremely restrictive Vancouver & BC is all about thwarting the influx of people and that's how the power-structure likes it.
A similar restrictive power-structure or multi-generational mindset has never been able to take over Alberta or Washington State. Thus, they are able to allow infrastructure to exist on a much larger scale.
