NEW YORK, NY – MAY 09: An Amtrak police dog keeps guard as Transportation Secretary Ray LaHood speaks to the media regarding national high-speed rail service on May 9, 2011 at Penn Station in New York City. Secretary LaHood announced that the U.S. government has awarded $795 million to increase rail speeds between Boston and Washington. This money is the largest share of the more than $2 billion in high-speed rail-grants that the state of Florida rejected in February. Amtrak, which won $450 million, will use the money to increase rider capacity and to improve travel times between Philadelphia and New York. (Photo by Spencer Platt/Getty Images)
