By establishing a national market, establishing a cattle sector on the Plains, and allowing certain people to become extremely wealthy through railroad investment, railroad expansion had an impact on the US economy.
There are many things the railroad did to improve the economy of the U.S.
Explanation:
The railroad made way of life much easier for those living at the time of its original development. Railroads themselves became large industries, and they stimulated the growth of iron and/or steel industries. In addition to this, they allowed for an increased efficiency for the transportation of goods. Lastly, railroads also allowed for the settlement of more and more land in the U.S., especially land found in the West, which had been largely left unsettled.
