In the 1830s, railroads began to be built in Virginia. In 1831, the Chesterfield Railroad began hauling coal from the mines in Midlothian to docks at Manchester (near Richmond), powered by gravity and draft animals. The first railroad in Virginia to be powered by locomotives was the Richmond, Fredericksburg and Potomac Railroad, chartered in 1834, with the intent to connect with steamboat lines at Aquia Landing running to Washington, D.C.. Soon after, others (with equally descriptive names) followed: the Richmond and Petersburg Railroad and Louisa Railroad in 1836, the Richmond and Danville Railroad in 1847, the Orange and Alexandria Railroad in 1848, and the Richmond and York River Railroad. In 1849, the Virginia Board of Public Works established the Blue Ridge Railroad. Under Engineer Claudius Crozet, the railroad successfully crossed the Blue Ridge Mountains via the Blue Ridge Tunnel at Afton Mountain.
