I rode it from Ansonia, where US 6 crosses it, to the southern terminus in Jersey Shore in 2017 during a cross-PA tour. Saw a bear the first day. Camped off the trail a bit north of Waterville. Hope you stopped for a sandwich at Wolfe’s in Slate Run. They are to die for.

BTW...It’s pronounced tee-uh-dot-un. My employer donated that abandoned line for the trail, but that was before my employ. There’s actually an interesting story behind the abandonment. A story about infighting among two railroad executives, but I won’t bore you all with it.
