Note: WNYP is the Western New York and Pennsylvania. They operate on a portion of the old Erie mainline.
We followed the WNYP OL-2 crew from Olean to Driftwood and back over Keating Summit before calling it a day...and late evening! Thanks to modern technology was able to get both video and still shots well past sunset at Keating Summit. The Nikon D7K was cooking at 16K ISO!!!
Following are links to the videos shot the same day by Kermit Geary, Jr.
