Sorry I was replying to a comment some idiot made that was filled with the worst logic and misinformation. I get pretty heated about it.
The funding for the HSR has already been given at least for the Chicago/Milwaukee and Chicago/St. Louis Corridor. It will probably be finished in 5 years. It's also pretty popular and it will run along an existing train corridor. This should really help to join Chicago and Milwaukee together more so and make a megatropolis in the near future. With a HSR, commute time between the two cities would be less then an hour.
