If a deep station were ever to happen in Calgary, my guess is that that's what we'd get here.
Escalators are expensive to run and maintain. You have to have elevators anyway, for strollers/wheelchairs, etc. The costs for taller and taller escalators is much more linear as elevation change increases, relative to Elevators. The cost of installing an elevator doesn't change a huge amount if it's a two stop elevator travelling 5 metres, or 50 metres. For a rough guess, let's say the cost double to increase an elevator from 5 to 50 metres of elevation change. An Escalator System would be more in the range of 8-10 times as expensive.
Remember, Calgary's newest LRT station has no escalators.
