(Ignore the sharp turn onto Hastings in Gastown, it shouldn't be that sharp, but I couldn't change it back b/c on MS Paint. I'll have a better map eventually.)
The Black line is the base case Hastings Line Extension into the West End- and the Red Line is a potential later spur that would connect to the False Creek LRT, the Arbutus LRT, and Kitsilano, leaving space for a future expansion up to Jericho Beach (as a parallel/alt to the Broadway Subway- and to allow expansion of the Broadway Corridor area into Kitsilano)
Black Line: $1.1 B, bored tunnel. Would be part of an impetus to rezone the West End up to Pendrell St. as CD-1, integrating the remaining underdeveloped parts of the West End into Downtown. (Technically possible today, but the pressure is not great enough to make it happen, especially with the current focus on integrating Downtown South, the Flats, NE/SE False Creek, and eventually Broadway and South False Creek.)
Burrard allows alternate transfers onto the Expo, taking pressure off congestion in Waterfront Station. However, it may not be possible to connect the two stations, and provide sufficient room for pedestrians for the new transfer- in which case, the station would be removed.
Robson Mall: Connects to the central part of the Robson Retail district- and would hopefully help revitalize the retail district.
Cardero-West End: As the name implies, connects to the new center of the West End's Community, located next to its community center, as well as Coal Harbor.
Devonian Harbour- Stanley Park: Provides a direct connection to Stanley Park- also the current terminus, as any extension further would mean drilling to get to the North Shore; not yet part of the plans until the Lonsdale Line begins to hit 75% of its ultimate capacity- it is effectively another parallel line.
Red Line: (not yet calculated), Of secondary importance- mostly meant to improve connections into the Southern West End and Kitsilano
Comox-St. Peters: Connects to Lord Roberts School Annex and St. Peter's- the nominal name for the new West End hospital following the construction of New St. Peters.
Sunset Beach: As its name suggests, intended to connect the Southern West End and Sunset Beach to the Skytrain Network. Not sure if the VAC will stay there or not.
Vanier-Kitsilano: Transfers to the False Creek LRT and Artubus LRT, funneling people away from the Canada Line. Also connects to Vanier Park, as the name.
I think listing all the connection points for the stations aren't that necessary, but let me know if I should try a different method to introduce most these lines.
