CLASSIC TRACK DIAGRAMS

PENNSYLVANIA RAILROAD

Middle Division

Former Pennsylvania Railroad main line between Harrisburg and Pittsburgh. At the time, the line was mostly four tracks, and had a significant number of manual interlocking towers. This diagram is based on a composite of information, not necessarily from the same exact eras. But this is a representation of the railroad as it likely existed from approximately the 1930's to 1950's. There were never 4 tracks between Spruce and Forge. Between View and Forge, the outside tracks were assigned to passenger trains and the inside tracks were assigned to freight trains. Between Forge and Antis, the inside tracks were assigned to passenger trains and the outside tracks were assigned to freight trains. East of Spruce, track 3 numbered from the south was mostly removed during the 1950's or 1960's. And during the 1990's, Conrail installed the present CTC, reducing the line to 2 tracks, 3 tracks between Tyrone and Altoona.
