This (geo)graphic was generated by the Federal Railroad Administration.
This map conveys some genius on the part of the DoT folks. $8Billion for high speed rail in the Stimulus Plan after idle conversation on the topic for the past 2 decades, which will establish enormous latent demand for more rail. They will pay for Atlanta and Savannah to Jacksonville, and Orlando to Tampa and Miami. But, they will not pay for Jacksonville to Orlando. I wonder how long that will last. And, Houston is connected to New Orleans, but not Dallas, Austin or San Antonio.
This is going to be interesting.
