After the Civil War, Willie Allen, who inherited Claremont Manor, moved to New York and sold the property. J. Frank Mancha, a Maryland real estate developer took on the project to develop, subdivide and colonize a new town there in 1879. Incorporated in 1886, the town of Claremont became the eastern terminus of the new Atlantic and Danville Railway (A&D), a narrow gauge railroad, which was completed to a point near Emporia called James River Junction, where it connected with a standard gauge track towards Danville. Unfortunately for Claremont, the A&D decided to connect its western leg with a new eastern terminus in West Norfolk on the harbor of Hampton Roads, and the line to Claremont, which was never standard-gauged, went into semi-abandonment. After some use for lumber transport as the Surry, Sussex and Southampton Railway, the rails were removed in the late 1930s.
