Not easily. The long term plans call for the terminus in Seton, and as a result, no right-of-way has been set aside like further north along the alignment. That said, 210th is a very big/wide road, maybe 16m can be found to squeeze a train in decades from now.
You think residents of this enclave would actually take public transit with the unwashed masses? Jay Westman said he envisioned residents getting helicoptered over from the airport when they fly in from whatever globe trotting they were doing. I wonder if they’re even targeting Calgarians?
Probably not that easy as you'd have to swing the train around back to 52nd street. Kind of makes for a weird detour and the city has to buy back a bunch of land for a right of way.
It's probably easier to have the future MAX Brown terminus at the roundabout at 210th Ave than it is to have the Greenline sent down there. Forgive the shitiness of the crayoning exercise:
