I guess that Vancouver's approach is to use light, automated trains with frequent service as opposed to massive subway systems like the ones in NY or London or Tokyo. The light and frequent approach has some appeal for me (esthetic appeal I guess), but ultimately I don't know how efficient / cost effective this will end up being.

It would be extremely expensive to extend the stations beyond 50 metres:
- expensive tunnel fans are located on both ends of each underground station, these fans would have to be relocated.
- there may be curves/dips before and after the 50 metre stations
- it will be difficult and extremely expensive to extend Bridgeport Station because of the flyover and track switches on both ends of the station.
You have to remember that the Canada Line 41-metre trains carry 334 persons which is equivalent to a 4-car Mark I train. With the 50-metre extension and an additional 10-metre middle car to to the 41-metre articulated paired trains, the capacity will be about 400 persons which is equivalent to a 5-car Mark I train.
And the proposed frequency isn't at all frequent like SkyTrain. For most of the day and peak hours, trains will be running every 3-4 minutes in Vancouver and every 6-8 minutes in Richmond and YVR. Late evening, it'll be 10 minutes in Vancouver and 20 minutes in Richmond and YVR. That's definitely not frequent.
And I wonder if the 250-metre single tracked guideways at the ends of YVR and Richmond will have any affect on frequency. Could we go up to every 60 secs in Vancouver and every 2 minutes in Richmond/YVR like SkyTrain?
