Western Pacific GP40 3506 and WP U23B's 2264 and 2254 are eastbound at Williams Loop near Quincy, California July 02, 1979. No photographer listed on slide.
A full moon softly illuminates the crossing point at the Williams Loop. A train, as yet unseen, approaches out of the Feather River Canyon to the west, turning the signal red.
A$$'s get back to grazing after bugging the photographer for pretzels, and are oblivious to the Feather River Express heading to Portola, soaring high above the Chandler Creek.
