Major Cities: Philadelphia, Harrisburg, Pittsburgh

Overview: The designated Keystone Corridor consists of two very different segments: Harrisburg–Philadelphia (Amtrak owned) and Harrisburg–Pittsburgh (Norfolk Southern owned).

East of Harrisburg:   Sharing some of the operating characteristics of the Northeast Corridor (NEC) main line, the Amtrak-owned and -operated Philadelphia–Harrisburg segment (104 miles) is a mature passenger corridor, with frequent intercity trains (14 round trips per average workday, most of which operate on the NEC beyond Philadelphia to New York) and commuter trains for part of the route near Philadelphia. This line has multiple tracks, full electrification, and almost complete grade separation from the highway grid. The remaining three public highway grade crossings on the Philadelphia–Harrisburg segment are being eliminated with current projects. Amtrak is planning additional improvements. Speed on the line is now up to 110 mph. Station improvements and new construction are being pursued at Lancaster and Elizabethtown.

West of Harrisburg: In contrast with Amtrak's portion of the Keystone Corridor, the segment between Harrisburg and Pittsburgh is a heavy-duty freight railroad, owned and operated by Norfolk Southern (NS), with only one passenger train round trip per day, the Pennsylvanian (New York–Pittsburgh), over its mountainous topography.

Status: The remaining three public highway grade crossings on the Harrisburg–Philadelphia segment are being eliminated with current projects. Amtrak is planning additional improvements, including the installation of the Positive Train Control (PTC) technology in use on the NEC. West of Harrisburg, a 2005 NS study suggests that significant infrastructure improvements would be needed to smoothly integrate additional passenger trains with the dense and growing in freight traffic.
