As follow-up to my posts last Monday and Thursday, I’ve posted a photo that reveals the identity of my mystery railroad. (see: https://briansolomon.com/trackingthelight/second-clue/)
This photo was exposed at Belfast, Maine on a warm morning in August 1980. It was the beginning of a memorable railroad journey with my father over the length of an iconic New England short line.

Congratulations to everyone who guessed correctly!
