Selective door operation (SDO) is used at some stations where the platform is shorter than the train, such as at Baker Street https://en.wikipedia.org/wiki/London_Underground_S7_and_S8_Stock#Features

Car length

  • Others: 19.660 m (64 ft 6.0 in)

The first 2 SkyTrain lines only have 80m stations, which can accomodate 5 of the newest cars. However, with SDO a 5 car train can become 7.

The Canada embasement Line was only designed to have 50m stations, not 152m stations like the Montreal Metro. Unfortunatly, the underbuilt Canada Line stations weren't designed to accommodate 5 car trains, only a 2.5 car joke of a train. Getting past the half-car B$, three 20m cars would form a 60m train. SDO can not only make a 3 car train possible, but a 5 car train length of 100m, despite its absurd 50m platform. It just would have been better to have built proper big city stations in the first place.

Of course Vancouver would opt to have shorter underground train stations than Montréal, Toronto, Edmonton, Seattle, SF & LA, because shorter trains help to increase urban transportation congestion. Unfortunatly, increasing congestion is a key component of the Vancouver city planning mentality & BC in general.
