Railroads made it easier for people to travel long distances. They also helped many industries grow. The iron, steel, coal, lumber, and glass industries all grew partly because the railroads needed their products. Railroads also increased trade among cities, towns, and settlements.
Two examples of how changes to the railroad system helped American Industries to grow is first the expansion West.
When the railroad was made, it made the Western Coast much more important, as both sides were linked with a reliable way of transportation. As a result of this, Industries from both coasts benefited as you could manufacture some parts in California and bring it to Georgia to make a product.
Another example of how the change benefited industries is how it made commerce avaliable large scale. The benefits of this also helped both coasts of the USA.
