Most main railroad lines are signaled, and many have PTC. However, smaller short lines often have no signals—this is called “dark territory.” The WNYP, which runs on the former Erie-Lackawanna mainline between Hornell, NY and Meadville, PA is all dark territory. There is a signal in Corry, PA that protects the junction there with the former Philadelphia and Erie (Pennsylvania RR) line between Erie and Johnsonburg. Both lines cross at Corry Diamond. Are there any sections that Amtrak trains run on “dark territory?”
