Steve: John Tory is full of crap, or at least those who advise him are. The subway will need new cars in 30 years, new track in 25-30, replacement of escalators and elevators in 25-30, new ventillation, lighting, etc, in 30-40, tunnel repairs on an ongoing basis to deal with leaks. Many of these have no equivalent for LRT unless we put it underground like the subway.This is a favourite comparison that has been used by the likes of Ford and Stintz to downplay LRT while ignoring the fact that if we build on the surface, we avoid huge capital costs for precisely those parts of a subway that must be built to last because they are so hard to replace. Remember all the parts of the existing subway system that are being rebuilt, or which don’t work very well today because they are too old.
