Railroads provided transportation necessary for the products of the surrounding dairies, farmlands and canneries to reach markets in the large cities. By the time Aberdeen was incorporated in March 1892, there were two flourishing rail lines with steam locomotives giving definition to the community. According to the first tax records in 1892, the B&O Railroad paid $82.88 in taxes that first year of incorporation. This railroad was not only a source of revenue, but added convenience for quick and comfortable transportation. Both it, and the Philadelphia, Wilmington and Baltimore, (now Amtrak) were considered assets when the federal government chose the area adjacent to Aberdeen for the site of Aberdeen Proving Ground in 1917. During World War I, World War II and the Korean War, the railroads served the nation in transportation of troops and materials.
