> The theory is that if we make passenger rail better, then consumers will be more willing to choose it over alternate, less environmentally efficient methods like driving or flying.

Then we don't want these CSX tracks that are shared with freight. We want all new high speed tracks that can compete. Most people in the US have a car, and you need a car most places you want to go. Fast trains mean they are enough faster than a car to be worth it. Otherwise people look at the train and think "but I have a car sitting in my driveway that can get there faster for less money". Most of the cost of a car is fixed (insurance and payments is by time not mile), so the cost to drive one more trip is very low.
