During late summer and early autumn the evening light changes quickly.
Compare these views of Amtrak 651 at Christiana.
The first was exposed on August 14th, the second was yesterday evening (Sept 4).
There are other differences too. The top photo was made with my Nikon Z7-II, the bottom is a product of my Lumix LX7.
Having just composed a summary of the Metroliner for my Amtrak book, I’m feeling nostalgic about these old cars (one leads as a ‘cab car’ in the bottom photo) which are now some of the oldest in revenue service on Amtrak.
