"Consider if you shut down Amtrak's Northeast Corridor, it is estimated that to compensate for the loss, you'd have to add seven new lanes of highway to Interstate 95. When you consider it costs an average of $30 million for one linear mile of one lane of highway, you see what a sound investment rail travel is."This reminded me of a blog post, by the Fruminator, who ran the math on what would be needed to replace NYC subway's morning rush hour with cars and parking.
It's staggering.
Makes you think twice about how mass transit is funded.
