The metro region's commuter rail lines converge at Penn Station and Grand Central Terminal, on the west and east sides of Midtown Manhattan, respectively. They are the two busiest rail stations in the United States. About one-third of users of mass transit and two-thirds of railway passengers in the country live in New York and its suburbs. Amtrak provides inter-city passenger rail service from Penn Station to Boston, Philadelphia, Baltimore, and Washington, D.C.; Upstate New York and New England; cross-Canadian border service to Toronto and Montreal; and destinations in the Southern and Midwestern United States.
