Excursions on the former Reading Perkiomen Branch between Emmaus and Pennsburg, Pennsylvania have been operated by three different railroads since the line was spun off by Conrail in the 1980’s. The first of these three was the Anthracite Railway, succeeded by the Blue Mountain & Reading, and then the East Penn. Here ATRW SW1 735, still wearing its Amtrak paint, leads a Pennsburg – Dillinger Tunnel trip through Zionsville.
