The development of the steel industry and the railroads was deeply connected. The benefits were going in both directions. The steel industry was providing the material for building the railroads. s the railroads were expanding through the country, new areas were becoming connected, some of which had the ore needed to produce steel. Through the railroad, the ore was easily transported to the manufacturing facilities, so more steel was produced. As more steel was produced, there was even more material for building the railroads, but also a cheaper material, sot he railroads developed even more. In this manner, both sides managed to contribute to their development and prosper greatly.
The territorial expansion of the US and the question of whether or not slavery would be allowed in the new territories was perhaps the single greatest factor leading up to the war, since before expansion, slavery was mostly confined to the South.
