Pennsylvania Lines LLC was a limited liability company that owned railroad lines in the United States that are owned and operated by the Norfolk Southern Railway. The company was formed in 1998 to own Conrail lines assigned to Norfolk Southern in the split of Conrail between Norfolk Southern and CSX Transportation; operations were switched over on June 1, 1999. The company is named after the old Pennsylvania Railroad, whose old main line was a line of the new company. In November, 2003, the Surface Transportation Board approved a plan allowing Norfolk Southern to fully absorb Pennsylvania Lines LLC,http://www.stb.dot.gov/decisions/ReadingRoom.nsf/0/f9b55306775a274585256dd5005c01b6?OpenDocument which was done on August 27, 2004.
