Wow, that's a very cool D&H sign BNSF FAN. With its beginnings in 1823 in the canal business at Honesdale, PA, the D&H was the oldest transportation company in the U.S. until its sale to the CP in 2000. I have a framed reproduction D&H Canal document from 1855 hanging in my train room that lists all of the "stations" by locks and mileage, bought at the museum in Cuddebackville, NY. I admit to being a bit of a closet canal fan.
"Call Before You Dig" Before there was an 8-1-1, you called the railroad agent. Remnants of the BN still exist today, if you know where to look. Minot, ND.
Going back a couple more decades, signs of the Great Northern still exist! "Ghost of Rocky" Trackside details catch a bit of last light near the Great Northern-built pedestrian overpass in Minot. Yes, you read that sign correctly; it does say Great Northern Railway. Rocky lives in 2019!
At the Railroad Museum of Minot, the old sign from Gavin Yard back in the GN days rests as a display above the dispatcher controls for Williston to Surrey, ND:
Former P&N station in Belmont, NC still sports this fine example of vintage tilework. I've always liked the P&N's logo with its three lightning bolts. The station is mighty neat too and stood at the end of a short branch off the mainline. When I shot these in '95, it hosted a small museum which has since moved.
Wow, lots to be seen inside the depot. On the train schedule board, Nos. 5 and 6 have been painted over and can be barley seen. These belonged to the Southern's Piedmont which called on Greensboro at far more hospitable afternoon hours.
