As part of the federal stimulus package in response to the economic crisis, President Obama announced possible funding for several high-speed corridors. It is not a full network but rather several clusters of high-speed lines (PDF, 3 MB). The funding of $8 billion is not definitively allocated to any projects yet, and it certainly is not enough to build all of them. Reading the small print on US HSR policy shows the intention is to upgrade existing lines, above all by elimination of level crossings (“grade crossings”). Even with those limited goals, some projects have been waiting years for funding.
