Recently sketches of the map for the proposed NYPC RR with grade profile have been provided to this testplant blog from the Interstate Commerce Commission, Finance Docket 4,741, February 27, 1930. It is noteworthy that closer examination finds that at its crossing of the Allegheny Frontal would be a grade of 1.337% for a distance of 7 miles. The line was to use a 1560 foot tunnel. A longer tunnel and / or combination of using the face of the Allegheny frontal to ascend could have lessened the grade. In fact, a five mile long tunnel was also proposed that lessened the grade to .03 per cent.
The steep grade was to have been from Houtzdale to a place about 5 miles northeast of Tyrone, PA using Emigh's Gap.

Both The NYPC RR and "Sam Rea" line would have used dramatic viaducts likely rivaling the one built across the Tunkhannock creek known as the Nicholson Viaduct 1912 - 1915 by the Delaware and Lackawanna Railroad.
If the rough location of the NYPC RR were followed across Pennsylvania for a new high speed rail (HSR) line, structures like this one in Germany would be built. A viaduct on this magnitude together with a longer tunnel at the proposed NYPC RR (Emigh's Gap) route over and through the Allegheny frontal would result in a lesser grade.
