Dennison (pop: 2,908) was born a twin to Ulrichville. The Tuscarawas County village is located exactly 100 miles from both Pittsburgh and Columbus, making it a natural location for a large railroad yard that was operated by the Pennslyvania Roailroad and employed close to 3,000 people. Today, the town remembers its railroad history with the Dennison Railroad Depot Museum located inside the former passenger station.
