By the early 18th century, several mines were being developed in Chesterfield County by French Huguenots and others. The mine owners began to export the commodity from the region in the 1730s. Midlothian-area coal from Harry Heth's Black Heath mines heated the U.S. White House for President Thomas Jefferson. The transportation needs of coal shipping stimulated construction of a paved toll road (Virginia's first), the Manchester Turnpike in 1807; and the Chesterfield Railroad, Virginia's first, in 1831; each traveled the from the mining community to the port of Manchester, just below the Fall Line of the James River. In 1850, the Richmond and Danville Railroad built Coalfield Station, a freight and later passenger depot, near the mines.
