I recently found a box of old slides that I shot on the Delaware and Hudson RR mostly between 1974 and 1976. The Adirondack is an Amtrak passenger train. But in the 70's it had the look and feel of a pre-Amtrak railroad operated pasenger train. The Alco PA locomotives generated considerable interest in this train in the railfan community. I have not been back the D H in quite awhile and I do not remember all the location names.
