I agree, the platforms are quite short and I have to say it was a big long-term mistake.....I really doubt the capacity, even if all the platforms were expanded to 50 metres, would be enough for our region in 2025. On our existing two SkyTrain lines, we use 80 metre (262 feet) station platforms and they are all expandable to 100 metres (have not been done yet, but probably by 2020).....compare that to the 40-50 metre platforms (50 metres = 165 feet).
Regarding frequency, this is our existing SkyTrain frequency:

*sometimes, we see trains every minute or even less during peak hours on the Expo Line....that's the great thing about automated systems
Now, compare that to the planned Canada Line frequency (note that this has also been added to the first post in this topic):

I'm sure if the public demands higher frequency (because I sure do!), the operators and Translink will give it to them.....but that means more trains and cars will need to be ordered (with the "Service Plan", 18 of the 20 trains will be in use already). The final 300-400 metres of the Richmond and YVR sections of the line will be single-tracked, due to NIMBY's along the Richmond portion of the line, so I'm not quite sure if we could have really frequent trains like SkyTrain's every minute or two.
Another way to increase capacity is to extend the platforms. Some platforms will be 50 metres in length, but those that are not are 40 metres long and are designed be expandable to 50 metres. This allows for a small 10-metre car, that will fit in between the existing two-20 metre car trains....increasing each train capacity by about 80 passengers for a total of more than 400. In addition, though I'm not quite sure if it is possible, maybe the Richmond and YVR portions can be doubletracked to allow a higher frequency.
When the Line opens in 2009, capacity will be about 8,000 passengers per hour per direction. With the service plan, it will be about 12,000 passengers er hour per direction and 15,000 when all platforms are 50 metres long with 50 metre trains.
