Chris M asks: The northeast corridor is the best train service in the US between Boston/NYC/ Washington downtowns and a number of the suburbs. Having to go up and down between downtown Washington and NYC for work, Amtrak is way too convenient compared to airline travel. There's no friggin way I'm ever gonna sit on a runway at LaGuardia for hours again. For getting between NYC/Boston/Washington very very cheaply, google up "chinatown bus". Most make some stops in the Bronx, the burbs, etc. The bus stops are frequently just people sitting on their luggage in the streets, and the operations may seem a little shady, but a lot of people on a budget go this way.
