A brochure is available that features the history of three counties along the 78 miles of Civil War rail line. Former slaves were impressed by Federals to complete construction of the Nashville and Northwestern Railroad from the capital city to Johnsonville on the Tennessee River. This railway provided a valuable supply line for Union armies in the western theater of war. The laborers who worked on the line were inducted into the 12th and 13th U.S. Colored Infantry Regiments, among the first black military units organized during the war.
