That makes no sense; 6 of the 8 Transit City lines would not be extensions of existing subway routes.It's cheaper to operate a few kms of subway extensions to existing lines than it is to setup and operate a whole new mode of transit. That's what makes Transit City so expensive.
I guess though if you are looking at only a few km of subway expansions instead of 100+ km of LRT, then it might well be cheaper to operate the subway! I hadn't realised that the SOS plan was so limited in scope!
