Before your edit I had a forehead slap, MP477 is Glendale, which is not very far from the southern terminus of the LA-Bakersfield district, Taylor Yard. Yeah, there were palm trees around the station, and the mention of "smog" pins it to the San Fernando Valley. There were palm trees in Bakersfield, but the desert and mountains in between were not hospitable for palms.
That was "home" stomping grounds, which is what piqued my curiosity.
Its such a cool shot. I've always had a soft spot for SP Cadillacs! One of the best looking engines ever.
