PRR: Summit of the Allegheny Mountains


At the Summit of the Allegheny Range we look east on Sugar Run Valley in Cambria County PA. Immediately below us #3 track exits the New Portage Tunnel, this is the eastbound main commonly referred to as "the slide" on account of its 2.0 to 2.36 grade descending the Summit. Joining from the left, tracks 1 and 2 curve around from Gallitzin and Allegheny Tunnel (now just the newer Gallitzin Tunnel since Conrail increased clearances on the line in the 1990's). While the line is quiet during a steady mid-day rain, activity here can be quite impressive, watching west-bounds top the Allegheny Range and eastbound trains begin there descent to Horseshoe Curve and ultimately Altoona the eastern base of the climb.
