Ns conemaugh line 2014 highlights
The Conemaugh Line is a rail line owned and operated by the Norfolk Southern Railway in the U.S. state of Pennsylvania. The line runs from Conpit Junction (west of New Florence) northwest and southwest to Pittsburgh, following the Conemaugh, Kiskiminetas, and Allegheny rivers, on the former main line of the Conemaugh Branch of the Pennsylvania Railroad (PRR). At its east end, it merges with the Pittsburgh Line; its west end is at the Fort Wayne Line at the west end of the Fort Wayne Railroad Bridge. The line was used by the PRR as a low-grade alternate to its main line (which is now part of Norfolk Southern's Pittsburgh Line) in the Pittsburgh area.

History
A short branch of the Pennsylvania Railroad from Torrance (on the main line) to Blairsville opened in 1851; only a small piece of this at Blairsville is still in use. The Western Pennsylvania Railroad opened from Blairsville west to Saltsburg in 1863 and to Kiskiminetas (Kiski) Junction (near Freeport) in 1864 or 1865. The line from Freeport to Allegheny (Pittsburgh) opened in 1866. A new, more direct line east from Blairsville was built by the Western Penn in the early 1880s, meeting the PRR main line at Bolivar. The PRR's Sang Hollow Extension, now only part of the Conemaugh Line west of Conpit Junction, opened east to Johnstown in 1876; the portion east of Conpit Junction was operated as a one-way line for westbound freight. All of the aforementioned lines became part of the PRR through leases and mergers, became Penn Central in 1968, and were taken over by Conrail in 1976. In the 1999 breakup of Conrail, the line was assigned to Norfolk Southern.
The Conemaugh Line is notable for being the recipient of a variation of the PRR's cab signal system in 1940, which eliminated the wayside signals between interlockings from Conpit Junction to Kiski Junction, requiring operation of trains by cab signal indication only. This system (whose visual NORAC Rule 562), modified by Conrail to operate bidirectionally, continues to be used by Norfolk Southern on this part of the Conemaugh Line; the section from Kiski to Pittsburgh also uses bidirectional signaling, however this section uses wayside signals but is NOT cab-signal energized. The entire line is remotely dispatched by Traffic Control System (TCS).
