Heritage unit, heritage background. Although Norfolk Southern Corp 24Z is rolling on the former Reading Railroad through Topton, PA on the afternoon of Wednesday, April 10, 2019, the setting is classic Pennsylvania Farm country for tribute of GE ES44AC 8102 (Pennsylvania Railroad). The The Allentown and Auburn Railroad in the background operates EMC SW 206, originally owned by the grandiosely named Philadelphia, Bethlehem, and New England Railroad. The “A&A” will open for tourist season soon, but does handle local freight that keeps the railroad running year round.
