FWIW - here's a complete collection of pictures (which I just stumbled upon) of the Penn Central's E40's - all six in PC black, including #4971 which shows the fire damage. http://www.rrpicturearchives.n...lthumbs.aspx?mid=874
#4973 and #4977 survived long enough to see some service in the Conrail era - at least the pictures show #4973 still active in 1976 and #4977 active into 1977.
