I visited Jack Bitner in Mount Gretna with Mal Ferrell, a friend of his and John Oross a while back and he showed us around the railroad, He had dug up many artifacts from around the enginehouse area. He had a bench or two, a wheel and couplers among the items. He also wrote a small booklet about the railroad. He had a 1/2" scale model of one of the locomotives and cars on display. He also had slides made of many or the photos taken of the line, including one of the coach which we enjoyed watching. Jack has since passed on and I don't know what happened to all his stuff. A guess would be the Lebanon County Historical Society.
