Amtrack is installing a highspeed rail service between Boston and Washington, DC. That happens to be about the only place in the country where they can do it because it happens to be one of the few sections of track Amtrack owns (much of the rest is owned by CSX, Conrail, etc.). And as far as bullet trains go, I know France has a good deal of them. They call it the KGV and Alstom (look over to the left
) makes them.
Matt who's hoping France orders some more KGV's
