Didn't want to put this in the green line thread... They've got new ideas over at Waterous and they're... Interesting?
The city's Plus-15 system provides a solution to how to build the Green Link, link to the airport and also run a train out to Banff.

"If CPKC gets on board, the province can build CADE from the airport to downtown within the CPKC rail corridor and then elevate the track for 5.5 km between the Bow River and 11th Street S.W. CADE’s 2.4-km downtown section could include three new stations along 9th Avenue: Downtown East (at 4th Street S.E. — Grand Central Station), Midtown (at 3rd Street S.W.) and Downtown West (at 11th Street S.W)."
No way it happens. I like the Waterous' though, they're like us but have money.
Using the first hydrogen-powered passenger train in North America, the Calgary Airport Banff Rail will connect Calgary's airport to downtown Calgary and out to Banff with train stops in between.
