Conemaugh Line
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〔(the NS Conemaugh Line )〕 along the former main line of the Conemaugh Branch of the Pennsylvania Railroad (PRR).〔http://triblive.com/x/blairsvilledispatch/s_522552.html〕 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 (now the Pittsburgh Line).〔(Keystone Crossings: Hobo's Guide to the Pennsy: The Allegheny Valley Railroad )〕
==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.〔, March 2005 Edition〕 The Western Pennsylvania Railroad opened from Blairsville west to Saltsburg in 1863〔, June 2004 Edition〕 and to Kiskiminetas (Kiski) Junction (near Freeport) in 1864 or 1865.〔, June 2004 Edition〕〔, June 2004 Edition〕 The line from Freeport to Allegheny (Pittsburgh) opened in 1866.〔, June 2004 Edition〕 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.〔(PRR Corporate History: Pennsylvania Railroad )〕 The PRR's Sang Hollow Extension, now only part of the Conemaugh Line west of Conpit Junction, opened east to Johnstown in 1876;〔, April 2006 Edition〕 the portion east of Conpit Junction was operated as a one-way line for westbound freight.〔(PRR Interlocking Diagrams: Altoona to Pittsburgh Main Line )〕 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.〔, August 2004 Edition〕 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).〔(【引用サイトリンク】url=http://www.trainweb.org/eastpenn/criconl.html )〕
