I think you are wrong here. It would indeed take a decent amount of money to get high-speed rail between here and Harrisburg (then on to Philly and other points east, although much of that is already upgraded), but if it was done, the train would be MUCH faster than a bus, and for the other reasons I noted above would be a much better competitor with airplanes. Of course this is also just one link in the chain--in the long run, fast enough trains could compete for passengers from, say, Chicago to Philly.

Planes, on the other hand, are inherently much faster. So, in my mind, trains to buses end up being somewhat of an apples-to-apples comparison, whereas the others (buses vs. planes, cars, buggies, etc.) are not.

So trains are "inherently" faster than buses (e.g., modern trains are easily capable of regularly operating at speeds of 150 mph or more). On the other hand, planes are only faster than trains once they are flying, and the total trip time for planes is encumbered by the time-consuming periods before and after the actual flight. That's part of why high-speed trains have proven effective competitors with planes whenever the routes in question are not too long--below a certain trip length, the airplanes don't make up enough time in the air to offset the extra time they take before and after.

I take the train whenever possible, knowing fully that it will make my trip more expensive and take longer.

But it shouldn't be that way. Trains with little or no operating subsidies are taking market share away from airplanes in many different cases around the world, and even in some cases in the United States. The problem is you are looking at passenger rail service that isn't even up to the standards of a century ago, let alone today, and comparing it to modern alternatives. But when given a real chance, modern passenger rail technology is in fact perfectly capable of competing with the alternatives in the right circumstances--and in fact the relative success of the Philly to Harrisburg section, which is not even all that great by modern standards, is itself proof of that fact.
