The now-preserved 964 (at Strasburg, PA) is pulling a heavy northbound train of Heritage equipment under the classic PRR position light signals between CP BUSH and Perryman. The 964 was built by GE for Amtrak in June of 1976, and was later renumbered to 603 when Amtrak rebuilt it in the late 1980s. It was delivered to the RR Museum of PA in January, 2004.
