The transportation revolution grew out of the American System. This radical transportation change developed along with the new infrastructure. Inventors in England and the US improved the steam engine, leading to sharp growth in the use of steam-powered boats and locomotives. Steamboats made river travel quicker and more reliable. Steam locomotives replaced horse-drawn trains and moved much faster. These two improved forms of transportation helped the US economy’s growth. Their use lowered transportation costs and shipping times. This caused an increase in trade between states. People and businesses in interior states could now purchase goods from the Northeast and the South. More goods were available to more places at a lower cost. The transportation revolution helped create the market economy, which is centered on the buying and selling of goods based on supply and demand.
