It is part of the reason why it'd cost more, we also have much higher safety standards (our rail cars are only allowed to crush in 1 inch, as compared to over a foot of crush allowed in Europe), an expensive right of way acquisition process, massive environmental impact statements ("Lets quantify the impact on the average person in this area"), and much more community involvement in the design process. Unless we can steal land and cut corners when building, the costs are unlikely to drop much.
