Amtrak Autumn Anniversary Aesthetic. A lone fisherman is up and out early on a crisp October Sunday morning as Amtrak 46 (P42DC, 50th Anniversary) leads Amtrak Train 157 over the Farmington River Railroad Bridge in Windsor, Connecticut. This 1867 structure, one of the state's greatest stone arch bridges, is the perfect setting amongst the fall foliage for a classic New England scene.
