which form of transportation made moving soldiers to battle smoother during the Civil War than in the past

During the Civil War, railroads played a significant role in making the movement of soldiers to battle smoother than in the past. The use of trains allowed for the quick and efficient transport of large numbers of troops, equipment, and supplies. This improved logistical planning and coordination, reducing the time it took to mobilize and deploy soldiers to various battlefields. It also facilitated the movement of wounded soldiers back to hospitals and the transportation of captured prisoners. Additionally, the development of telegraph lines alongside railroads enabled faster communication, further enhancing military planning and troop movements.
