"Ask A Gettysburg Guide #120 - Civil War Railroads," features Licensed Battlefield Guide Rich Kohr discussing the crucial role of railroads during the American Civil War.

Here are the key takeaways from the discussion:

Railroads' Crucial Role: The Civil War was the first major conflict where railroads were essential for supplying armies, moving troops, and transporting equipment on a massive scale.

Rapid Expansion Before the War: In 1840, the U.S. had 3,000 miles of railroad. By 1850, it grew to 9,000 miles. By 1860, it reached 30,000 miles, with a significant disparity between North and South: the North had 21,000 miles, while the South had 9,000 miles.

Differences Between Northern and Southern Railroads: Southern Railroads: Primarily "market railroads", designed to transport commodities like cotton, tobacco, and sugar from farms to ports, often with shorter mileage.

Northern Railroads: More focused on connecting cities and commerce, with some relying heavily on passenger business.

Impact on Manpower: The railroad boom in the 1850s influenced the available manpower for the war. Southern railroads largely used slave labor, while Northern railroad construction brought in European immigrants, significantly increasing the white male population of military age in the North by 1860.

Gauge Issues: Railroads in 1860 were not standardized in terms of "gauge" (the distance between rails), with about a dozen different gauges in use. This often meant freight and passengers had to be transferred between different rail lines, as railroads frequently didn't physically connect.

Southern Reluctance to Modernize: Despite the recognized need to connect railroads for military purposes, the Confederate legislature debated extensively in 1861, with arguments centering on military necessity, funding, and whether connections should be temporary or permanent. A significant argument against expansion was the belief that the war would be over quickly.

Protection of Railroads: While initially neglected by figures like Secretary of War Cameron due to personal financial interests, later in the war, the Union built blockhouses and established a "railroad division" to protect vital lines like the Baltimore and Ohio Railroad.

Compensation and Management: The U.S. government compensated private railroads for their use by offering higher rates for government shipments. The North also consistently appointed experienced railroad managers to positions of authority within the War Department, which was a significant advantage.

Train Speeds: Wood-burning freight trains typically traveled around 15-20 mph, while passenger trains could reach 30-40 mph. Coal-burning locomotives, which were beginning to appear, offered higher speeds and would become more prevalent after the Civil War.
