For a line that first opened in 1985, it took until 2025 to try to start running 5 car trains of the latest generation of rolling stock. Considering that Greater Vancouver has a narrower road network than Montreal, the SkyTrain stations should have been designed to accommodate 10 car trains.
While the Alstom_Mark_V vehicles look nice & modern, a 5 car train is a half-length reminder of how much nicer & better a 10 car train would look.
Just because the SkyTrain is considered to be a Light Rail Vehicle, there still should have been a provision to eventually have the stations to be as long as the longest ones on the Montreal Metro. The Montreal Metro has 500 foot or 152.5m long stations, which can accommodate a 9 car train. Unfortunately, the first 2 SkyTrain lines only have 80m stations, which are just barely over half the length of the longest STM stations. https://www.stm.info/en/info/networks/metro

Apparently, in order to reduce construction costs, the first 2 SkyTrain lines have stations that are only 250 feet. Half the length of a 500 foot long Montreal train, but BC usually takes the half-assed option with its small-scale of infrastructure development.

| Train length | 152.43 m (500 ft 11⁄8 in) |
|---|
https://en.wikipedia.org/wiki/MPM-10#History Approximately, a 500 foot train divided by 9 cars = 55.55 feet, or just under 17m.
Despite the SkyTrain cars not running on rubber tires, each 55 ft. coach is very close in length to the 55.6 ft Montreal Metro coaches.

1⁄2 in) long each and come in articulated pairs."
