The car end closest to the camera is T&NO 3xx22. Car to the left is SP (can't read the 5-digit number)
Sharp photo, thanks.

Courtesy of the USC Digital Archives, here is a link to an image of a freight car “assembly line” in Los Angeles (possibly Southern Pacific shops?) in 1900.
Use the slider above the image to enlarge it.
There also is a good end view of an early T&NO box car.
