The ONLY railroad to pass through Den'ts Run was an off shoot of the Philadelphia - Erie Railroad and it was called the Low Grade. Now, what you have after reading this is two or three guys who worship Punxsutawney Phil and sample their own brand of Pennsylvania Mountain Juice. They're out to get their 5 minutes of fame and nothing more.
On June 23, 1863, S. Wimmer came to Elk county as principal assistant engineer of the Pennsylvania company, to complete the Philadelphia & Erie Railroad from Whatham to Warren; of which E. Miller and Milton Courtright were chief contractors. In July, 1864, the road was practically completed; but not until March, 1865, did Mr. Wimmer sever his connection with the road, owing to his acceptance of a position as engineer on the Vera Cruz railroad, where the Wimmer bridge stands as one of the memorials of his work near La Cumbres de Maltrata. In March, 1869, he took charge of the building of the Benezette and Driftwood division of the Low Grade, and subsequently of the road from Benezette to DuBois, which was completed in 1874.
