Yes I know the central part will be underground as it should be but the rest should have been elevated. The CT has too many stations both at grade and underground adding to the costs for little return. Also the underground stations themselves had to be made significantly larger than needed than if the system was grade separated because the system will suffer from much lower frequency capacity.
Miller proclaimed that LRT would offer the best of both worlds.......... high capacity, high frequency but lower costs and faster construction than subway but as Torontonians are quickly realizing instead it offers the worst pf both world.............high costs, lower capacity, less frequent service, less reliable but coming in a subway costs and timetables.
