CR 2636 Harrisburg, PA 7-9-1977

A ground shaking rumble in Harrisburg revealed 10 CR units pulling freight on a dark July, 1977 day! Rolling quickly through, I captured the last seven units in this picture. The entire consist included leading unit CR SD-45 6163 followed by SD-35 6009, an unidentified third unit, GP-38-2 8090, PC U25B 2636, GP-38-2 8124, SD-40 6288, SDP-45 6696, GP-38 7806, and trailing SDP-45 6697.
