For proponents of federal funding of high speed rail, my question is where is the demand? With the exception of the Northeast Corridor, what cities would benefit from having a bullet train running between them? If the purpose of the rail line is to replace road and shuttle flights, what cities have the demand required to justify the expense of one of these systems? The only place I see would be the Washington-New York- Boston Route, currently served by acela (not exactly high speed, but faster than normal trains). With the exception of upgrading this route to seperate track bullet trains where else would this work?
