Unfortunately, all the Skytrain stations should have been built to be at least 500 feet or 152m in length for future demand. Instead, the first 2 lines are barely half the length of a Montreal Metro station.

It should have been built to handle at least a 10 car train, but 9 coaches is still pretty good.

The C Line was deliberately built with stations that are only a 3rd of the length of a Montreal Metro station. So instead of a 9 car train, the C Line will max out with just 3 car trains. All that money spent and yet there was no provision for a longer big city train.

For some reason, Vancouver and BC can't seem to build something right the first time.
"Unlike Bombardier ART trains, the Hyundai Rotem trains will not be operated as longer four- or six-car trains. Through inserting a middle "C" car at the articulated joint between two end cars, available capacity will be similar to a four-car Mark II or a six-car Mark I train. The Canada Line's station platforms are expandable to 50 metres (160 ft) in length to accommodate these future three-car trains; the five busiest stations are already 50 metres (160 ft) in length. The Canada Line has a designed future capacity of 15,000 pphpd when operating three-car trains at two-minute headways." https://en.wikipedia.org/wiki/SkyTrain_rolling_stock#Canada_Line_fleet
This is still the best article about how inept an shortsighted regional planing is in Greater Vancouver. https://dailyhive.com/vancouver/canada-line-skytrain
