Yes, enslaved people played a massive and foundational role in the construction of the railroad infrastructure in the Southern United States during the 19th century. Historians have documented that prior to the American Civil War, nearly every railroad built in the South relied on enslaved labor. Railroad companies either owned enslaved people directly or, more commonly, "rented" them from local plantation owners. These individuals performed the grueling and dangerous work of clearing dense forests, leveling ground, blasting through rock, and laying heavy iron tracks. In the North, railroads were more commonly built by immigrant labor (such as Irish and Chinese workers), but in the South, the entire economic model of rail expansion was tethered to the institution of slavery. Even after the Emancipation Proclamation, many formerly enslaved people were trapped in "convict leasing" systems, where they were forced to continue building railroads under brutal conditions that mirrored slavery. In 2026, there is an increasing effort by historians and descendants to ensure these individuals are recognized for their forced contribution to the industrial birth of the United States.
