An eastbound dead-head "push-pull" move sees 5 Bombardier cars being pushed by an "American Cities Sprinter" ACS-64, No. 906 through Exton, PA bound for Frazier. The set runs from Philadelphia's 30th Street Station to Thorndale before returning light to the shops at Frazier, PA. A larger depot exists here, finally, under construction to the right, not in sight, at the time of this image.
