The name for the railroad is taken from a point on the Pennsylvania Railroad where the PRR's Conemaugh Line (the former Western Pennsylvania Railroad) and Allegheny Branch (former Allegheny Valley Railroad) met.
The section of the Kiski Junction Railroad's line that runs from the former Kiski Junction, across the bridge over the mouth of the Kiskiminetas River, and along the Allegheny River, was part of the Pennsylvania Railroad's line from Pittsburgh to Oil City, Pennsylvania.
