I think that high speed rail would be great, but it's hardly a substitute for a system like blue 22. I really just don't get the opposition, other than Weston NIMBYism and instinctive reacton against PPPs. Sure, many people, likely including me, won't use the service. So what? Many people will, including business people and tourists. The airport route is the bread and butter for many cabbies and the downtown-airport bus can charge over $20 for a route that can take over an hour. I'd say that's more than enough of a market. There's also something to be said for GO service (at the very least, a people mover to the Georgetown line is a no-brainer) but cities all around the world are introducing express, premium services to their airports. I'm not just talking about London and Paris, either. Look at Oslo, Stockholm, Munich, Chicago.
