If you build it now, at 50 years you will have to replace a good chunk of the original capital investment due to wear and tear, etc - so in effect you're paying for it twice - once when you didn't need it, and once when you finally do. Bit of a simplification, obviously.
Fair enough, what I'm curious about though is whether the tunnels that will house the burried section of the LRT on Eglinton will be large enough to be converted to subways or whether at that point they'd have to bore them out even wider.
