I found this short video on You Tube on the train wreck on the Maybrook Line in Poughkeepsie in 1966. It is very grainy film.

The bigger wrecking crane (“derrick”) was the D-100 from New Haven. The smaller ones from Maybrook.
This is Bowman’s Tower in Washington’s Crossing State Park in Washington’s Crossing, Pennsylvania. The views from here are spectacular.
