The Harrisburg Subdivision is a railroad line owned by CSX Transportation in Pennsylvania. The line is located in Philadelphia, and connects Greenwich Yard and the Philadelphia Subdivision with the Trenton Subdivision[1][2] along a former Pennsylvania Railroad line. Much of the Harrisburg Subdivision is the High Line' or West Philadelphia Elevated along 31st Street over the 30th Street Station area.
The line begins at Greenwich Yard in South Philadelphia, where it meets the Philadelphia Belt Line Railroad. It heads west alongside the Delaware Expressway (Interstate 95) and then north along and partially elevated over 25th Street, turning west at Washington Avenue to cross the Schuylkill River on the Arsenal Bridge. At Arsenal Interlocking, on the west side of the Schuylkill, a branch runs southwest alongside Amtrak's Northeast Corridor to a junction with the Philadelphia Subdivision near Lindbergh Boulevard.
The main line heads north from Arsenal, rises onto the elevated structure, and crosses to the west side of the Northeast Corridor. It heads north above 31st Street, finally touching down in the southeast approach to Zoo Interlocking. It leaves that interlocking to the north, staying on the west side of the Schuylkill River, and ending at the Trenton Subdivision at Belmont.
