The Pennsylvanian is a 444-mile (715 km) daily daytime Amtrak train running between New York City and Pittsburgh via Philadelphia. The trains travel across the Appalachian Mountains, through Pennsylvania's capital Harrisburg, the Pennsylvania Dutch Country, suburban and central Philadelphia, and New Jersey en route to New York. The entire train ride takes about 9 hours total: 1.5 hours between New York and Philadelphia, 2 hours between Philadelphia and Harrisburg, and 5.5 hours between Harrisburg and Pittsburgh.
The Pennsylvanian uses the same Amtrak-owned Philadelphia to Harrisburg Main Line as the Keystone Service trains, but continues further west via the Pittsburgh Line through Altoona and the Allegheny Mountains, eventually terminating its run in Pittsburgh. The Main Line and Pittsburgh Line collectively make up the Keystone Corridor, a federally-designated corridor for high-speed rail service.
