Looking rather ratty, this old unit gets some attention in the 70s. From my collection, photographer unknown.
On a hazy summer day in Alabama gray concrete and steel blend with faded, dirty Amtrak 204, resulting in an almost color-free image.
David is correct, this train is just beyond the Attleboro Tower and the Middleboro Secondary. This will be as good as it gets untill the Acela system comes.
