I found this on CT's website. It shows the tentative schedule for 4 car train extensions. I presume it will be updated sometime later this year to show a more firm date on the ones listed as "2012 or 2013." Also note the ones which need to be closed. If no more are added, I must say I'm surprised that it is only 3 total including Southland. The Chinook closure will be a bitch to deal with since a lot of bus routes (especially crosstown routes like 72/73 and 23) connect through that station.
This is in addition to the following assumptions:
- Victoria Park/Stampede will be extended during the hockey offseason, and not during Stampede
- SAIT and University will be extended during the months of May-August
- Banff Trail will be extended during the months of December-May
