Bush-Whack For Amtrak

"It's true that Amtrak is flawed -- the current disruptions in its Acela high-speed service in the Northeast, due to brake problems, is an example. But at the same time, the president's budget proposes $284 billion in funding for highway construction over the next six years. How did it come to pass that Amtrak's operations, and ability to correct problems, must be financed by ticket revenue while the national highway system is subsidized through taxes?

Which system, railroad or highway transportation, is unworkable?"
