LATE UPDATE: This piece by BruceMcF is a must-read: How to build a national high-speed rail system.

President Barack Obama and Transportation Secretary Ray LaHood released a

blueprint for a new national network of high-speed passenger rail lines Thursday, saying such an investment is necessary to reduce traffic congestion, cut dependence on foreign oil and improve the environment.

The president’s plan identifies 10 potential high-speed intercity corridors for federal funding, including California, the Pacific Northwest, the Midwest, the Southeast, the Gulf Coast, Pennsylvania, Florida, New York and New England.

It also highlights potential improvements in the heavily traveled Northeast Corridor running from Washington to Boston, Massachusetts.

The economic stimulus package included about $8 billion for high-speed rail projects, and Obama is seeking an additional $1 billion each year for high-speed rail in the next five federal budgets.

After the jump I’ve got more details on how this funding could benefit Iowa.
