Well my wife wouldn't let me go out of my way to railfan but I did manage to be in the right place at the right time to catch 2 trains.
The first was a Delaware-Lackawanna pulled by an Alco RS3, was amazed to see this coming. We were in the Delaware Water Gap National Recreation area on the New Jersey side taking pictures and I heard it chugging round the mountain.
