In the 1890s, small communities began to develop along newly established electric railways which serviced the area, as real estate developers began subdividing the land. One such community was Fostoria, developed by the Fostoria Land and Development Company in 1890, which took advantage of the Washington, Arlington, and Falls Church Electric Railway. The railroad provided passenger service from Rosslyn to East Falls Church and ran along Four Mile Run. By 1907, the neighborhood was known as Highland Park - the earliest houses constructed in the Westover area are located within this community.
