Intercity Rail

Intercity train service is operated out of 30th Street Station by Amtrak. Amtrak runs most services along the electrified Northeast Corridor, serving a densely urbanized string of cities in the northeastern United States.

 Amtrak runs at least 53 trains each weekday on its busiest route: Philadelphia to New York City. Regular train service along the Northeast Corridor consists of the Acela Express, a high-speed train between Boston and Washington, and the Northeast Regional, a local service with northern terminals of either Boston, or Springfield, Massachusetts (using a diesel locomotive), and southern terminals of Washington, D.C., Newport News or Lynchburg, Virginia. Amtrak runs several long-distance rail routes along the Northeast Corridor, including night trains. Long-distance trains run primarily on tracks owned and maintained by private freight railroads, and serve 39 states including the District of Columbia.
Amtrak operates two routes along the Keystone Corridor, connecting Philadelphia to Harrisburg and Pittsburgh. The Keystone Corridor consists of two different segments: the section between Harrisburg and Philadelphia, and the segment west of Harrisburg to Pittsburgh. The eastern segment of the line, owned by Amtrak, is fully electrified and almost completely grade separated. The Philadelphia to Harrisburg section was upgraded to allow for top speeds of 110 miles per hour (180 km/h). The section west of Harrisburg is a heavy-duty freight railroad owned by Norfork Southern. Regular service on the Keystone Corridor consists of the Keystone Service, which travels between Harrisburg and Philadelphia. After stopping in Philadelphia, certain trains continue along the Northeast Corridor to New York. The western section traverses mountainous terrain, and has obstacles limiting track speeds such as the Horseshoe Curve. The Pennsylvanian, consisting of one train in each direction per day, is the only route between Philadelphia and Pittsburgh.
