The claim that Calgary is going to *replace* its downtown surface route is a myth. It's on the books to remain for the long term.
Right now, two separate lines - the NW-S and the W-NE - converge onto the downtown 7th Ave corridor, and do so at grade crossings (i.e. incoming trains on the NW-S line have to cross the tracks of the W-NE line's outgoing trains).
The long term plan is to move the NW-S line into a tunnel under 8th Ave (sort of their version of Sparks St), while the W-NE line remains on 7th Ave.
Were it not for the grade crossings where the lines converge - something we in Ottawa have the ability to avoid (think Hurdman and Bayview) - it's unlikely they'd be considering a tunnel any time soon. They just have no practical way to grade separate those two crossing points.
A third line, the N-SE line, will also go in a tunnel because it will operate at right angles to the other two, which also places it on the narrow end of their downtown blocks, with the consequence that there's not enough distance between streets to have long enough platforms.
It's also worth pointing out that everywhere else, these lines are at grade for considerable lengths. They go under or over some roads but across others. For instance, there's no way that Calgary's planners would have agreed to run the WLRT in a long tunnel under Richmond Rd when there's a perfectly usable corridor right next to it. Using the Rochester Field route, they may well have gone across Richmond at grade, but they likely would have ducked under Woodroffe.
Overall, the Calgary approach is pragmatic. Ours is dogmatic.
