With the introduction of railway service in 1867, chiefly the Delaware, Lackawanna & Western Railroad, Waterville became a major shipping point for hops-related cargo; "Waterville Hops" and hop extract were shipped to brewers all over the world. The economic prosperity fueled by the hop industry was reflected by merchants building fine Victorian-style homes. By the 1920s, hop production began to wane, due primarily to poor agricultural technology. By the close of the 1940s, Waterville's working hop farms had all been converted to other uses. Some locals continue to grow hops as a recreational "tip of the hat" to Waterville's past.
