Dieselization is catching up to the N&W as these Alcos and an EMD Geep await their next assignment at the water tank at Norton, VA. RS-3 306 is ahead of the 308 on Dec. 29, 1956.
The date is approximate. I was stationed at the Naval Amphibious Base for 6 months - Lambert's Point was a favorite place to relax. There was a park adjacent to this site.
