Amtrak (AMTK) 744 - EMD SW1

AMTK 744

Finally tracked down info on this relatively obscure little switcher. It was originally built for PRR as #9145. Absorbed by Penn Central as #8575, it then became first Amtrak #257 and finally as seen in this photo by Forrest Trittenbach as #744. After all of that merging and converging, it was finally retired July 1986 at Wilmington DE. Behind it sits another obscure Conrail unit #6867. Looks to be an RSD-12 but can't find it listed anywhere.
