The "Daniel Nason" is the oldest steam locomotive in the Museum's collection and one of the oldest surviving locomotives in the nation. With a 4-4-0 wheel arrangement, the locomotive is the only surviving "insider," a design popular with railroads before the Civil War, with cylinders and main driving rods between (rather than outside of ) the locomotive side frames. The locomotive had a top speed of 60 mph. Part of the Purdue Collection.
