The Railroads
Railroads completely transformed the United States socially, politically, and economically during the Gilded Age. Literally the engine of the new industrialized economy, they facilitated the speedy transportation of raw materials and finished goods from coast to coast. In addition to raw materials, these “iron horses” carried people west to settle the heartland and the frontier. As the railroads grew in power, they exerted increasing influence on local and state governments, eventually prompting Congress and reform-minded presidents to pass laws to regulate the new industry.

America's lack of involvement would result in the Axis powers taking over the world's territory.
