Pennsy Legacy.
Amtrak Metorliner cab car 9638 (nee Penn Central 812; Budd, 1967-1970) is on the front of Keystone Service train 645(31), seen approaching Harrison Station. Similar to the cab car, the signals on the catenary bridge above are also originally from the Pennsylvania Railroad and have been upgraded by successor railroads. The signals were originally PRR position lights, which have been converted by Amtrak into position color lights. The Metroliners were originally ordered by the PRR, but the railroad was folded into Penn Central before they were delivered.
