Philadelphia to Harrisburg Main Line

For the Norfolk Southern (formerly Reading Company) line, see Harrisburg Line.

The Philadelphia to Harrisburg Main Line is a rail line owned and operated by Amtrak in the U.S. state of Pennsylvania. The line runs from Zoo Interlocking in Philadelphia, where it meets the Northeast Corridor, west to Harrisburg along the former Pennsylvania Railroad main line. It is part of the longer Keystone Corridor, which continues west to Pittsburgh along the Norfolk Southern Railway's Pittsburgh Line.^[1]

Amtrak's Keystone Service and Pennsylvanian operate over the entire line. SEPTA Regional Rail R5 Paoli-Thorndale trains operate east of Thorndale, with the rights to continue revenue service west to Parkesburg and to run west to Cork Interlocking (just east of Amtrak's Lancaster station) to reverse direction.^[1]

Freight trackage rights over the whole line are assigned to the Norfolk Southern Railway. The Canadian Pacific Railway also has rights over a small piece near Harrisburg, from the west end to Roy Interlocking in Royalton, to allow CP trains to get from the end of their Sunbury Line or Allentown to Perryville, Maryland.^[1]
