Exactly. Our local route, occasional touted as a candidate for high-speed rail, is Toronto-Montreal. The problem is that even a fast train will take three times as long as flying (especially because one of our airports is downtown), there are flights leaving every 15-30 minutes, and airfares are often just as cheap as rail. The bonus is that unlike rail, the airlines operate with subsidy; the airports and the air navigation system are privately owned.
Don't worry. When this becomes obvious it will be too late, and those elitist free-riders on the airlines will be taxed to pay their fair share of the necessity of train service. Over time the train will become the only available solution as obviously inefficient air travel will fall into disuse. Then everyone will appreciate the intrinsicly superior nature of rail transit, and we will revere the thoughtful foresight of the visionary founders of the high-speed rail system.
