For another, settlement of the 'wild West' was made easier, as was increased growth of areas already settled. For yet another, military operations became more sophisticated and generally more power-packed: during the Civil War, Union and Confederate forces could be quickly reinforced or moved to areas of special need due to the rapid transportation provided by railroads.
