I had the fortune to help operate Frank Miller's recreation of the 2 rail Delta Lines a number of times at Mr. Miller home near Newtown, Pa. before he moved. Frank Miller hand made most of the cars and I believe some engines himself. Operating nights consisted of about 5 of us and a fast clock with a schedule we all followed with updates from the dispatcher sitting at a huge ctc board. This was a master designed layout, offering many hours of operating enjoyment.
