In March of 1971 my Dad took the train south to the San Jose branch office of the company that he worked for. I believe that this is in San Jose.
Regardless I really like the detail in this image, the open doors and the lubrication drips below the coupling knuckle.
There are a few photos at the rrarchives.net states that this engine ended up life in Utah. I recall seeing this and several other 4000 numbered Alcos in line there as well.
I suppose that I’ll find that box of slide photos as I trudge through the 60,000 or so.
