Penn Central jade green boxcar circa 1976. From the internet., a photo by Eddie from Chicago on Flickr.
I found this photograph on the internet.
Unfortunately...I do not remember what web site it was on. However once I dofind out, I will make sure that the photographer gets the proper credit for it, as this isn't one of my own photos.
One of my all time favorite railroad color schemes I fondly remember growing up in Chicago during the 1960's and 70's, was the "Jade" or "Empire" green originally used by the New York Central and later Penn Central railroads. This Penn Central green boxcar was photographed way back in 1976.
