John H. Armstrong (November 18, 1920 – July 28, 2004) was a mechanical engineer, inventor, editor, prolific author, and model railroader best known for layout design and operations. He was married for 44 years to Ellen Palmer. They had four children. Early life He was born and raised in Canandaigua, New York, and began designing his Canandaigua Southern Railroad model layout when he was 14 years old. After earning a mechanical engineering degree from Purdue University, he settled in Silver Spring, Maryland in the late 1940s. He was employed at the Naval Ordnance Laboratory of the United States Navy in White Oak, Maryland and contributed to the design of weapons systems for nuclear submarines. Following his retirement from the Navy, he was a contributing editor for Railway Age magazine for ten years. Model railroad construction In evenings and on weekends he began building his Canandaigua Southern Railroad O scale layout in the basement of the modest Armstrong family home, carefully cutting the cross-ties from balsa wood, setting them on rail-beds made from scale-sized gravel, and then laying out each length of track and carefully nailing it into place with tiny railroad spikes to scale that were hammered into the cross-ties one at a time. Armstrong was extensively published in the U.S. railroading press, publishing 13 books including "Railroad: What It Is, What It Does" (1978) and articles for Model Railroader and trade magazine Railway Age. He has over 300 references in the Trains Magazine Index. Influence on the hobby Armstrong wrote many books and articles on the subject of railroading and model railroading. His personal model railroad, the Canandaigua Southern, was the subject of many newspaper and magazine articles by other writers. In the late 1940s, Armstrong submitted a track plan to a contest sponsored by the magazine Model Railroader. His plan was so successful that it led to an invitation to contribute an article to the magazine on the Canandaigua Southern, which appeared in 1946. He remained a regular writer for the magazine, contributing 76 articles over his lifetime. His last article, was 'Main line through the mountains', was published posthumously in the April 2005 issue. He also held at least four patents. Armstrong was well known in the model railroad community in part through his memberships in the National Model Railroad Association, the Capital Area O Scalers and the Lexington Group. He was named to the O Scale
