A 1989 Conrail diagram book, available on the WWWeb at George Elwood's marvelous "Fallen Flags" railphoto site, lists Conrail 2789-2798 (the last U23B-- and last domestic U-series diesels-- built) as having the GT581 main generator. Other sources (e.g. the U23B roster in "Extra 2200 South" issue 75) list these units as having the GTA-11 traction alternator.
My SUSPICION is that the Conrail document is in error. (A few pages earlier it lists 2777-2788, the U23B built for the Lehigh Valley, as being ex-Penn Central, and, as Descartes said, "it is prudent never to trust completely those who have deceived us once." (Grin!))
I think some of these units are still in existence, having been sold to shortlines. Does anyone here know for certain what sort of transmission they had/have?
