The transition from steam to diesel is well underway as we look at the Reading Railroad between Reading and Norristown, PA in scenes photographed in 1945. Then join us for the last day of operation, July 15, 1955, for the “Mule Train”, a mixed train on the Perkiomen Branch between Emmaus Jct. And Perkiomen Jct. With onboard and trackside views. Then, towerman Charles Bealer provides us with views from Catasaqua, Union Street and East Penn towers showing activities of the Lehigh Valley, Reading, Lehigh & New England and Central Railroad of New Jersey.
