In Palmerton Pa, the Chestnut Ridge Railway runs with a former Pittsburg and Shawmut GP10, and has an S2 that was being used until recently. They have two customers, the successor to NJ Zinc, Horsehead Resources, and I believe is an aggregates firm near the end of serviceable track. Sometimes there are only one or two covered hoppers a day, other days there are six or seven, I believe, plus a boxcar for the agg. shipper. Most activity is from early morning to afternoon, and is withing a two mile area.
