Hello there!
Railroads played a HUGE role in the acceleration of industrialization. It played a huge role because railroads gave a <u>huge demand in things like steel, iron, coal, and etc</u>. Since it made a high demand in these items, people started to make businesses that sell these items. It made the industry grow because it was a <u>source of transportation</u>, which helped products, workers, and other things get around the nation. People use to have trouble getting things around because there were a limited amount of transportation resources, so the railroads solved this problem. If it wasn't for railroads, people would have trouble getting around places or sending products to other places.
Railroads help create national markets by<u> making it easier and faster for companies to ship their products to other locations </u>around the nation. Because of the railroads, national markets started to expand around the nation because there was an easy transportation option to bring products to another place. As the railroads started to expand across the country, markets followed the railroads.
To bring this all to a conclusion, railroads played a huge role in the acceleration of industrialization by providing <u>TRANSPORTATION </u>for people and products.
