Which makes it all the more mind boggling that the Scarborough and Eglinton West extensions are going to be primarily underground. Billions down the drain for nothing. We should be avoiding tunnels wherever possible outside the dense central part of the city.Isn't the Ontario Line going to be another subway line? I haven't heard that they're going for an Eglinton LRT-like "pre-metro" solution. They're cutting down on the size of the trains and the amount of tunnelling to save on costs. The entire Montreal Metro uses smaller trains, and significant parts of NYC's subway are built above ground outside of Manhattan.
