01. How did railroads most affect the economic growth of the United States?

At the rise of the Industrial Age, or the Gilded Age, railroads became the industrial epicenter. With the completion of the transcontinental railroad, the movement of supplies and goods became easier, faster, and much more efficient. However, large railroad corporations began to monopolize the market and buy out small businesses before they could take a toll on their service. The economic growth of the United States is due, a considerable amount, to the railroads. The railroads most affected the growth of the economy through the transportation of goods. It became easier for businesses to manufacture or produce goods, transport them, and sell them to make more profit.
