We all learned it in school: molecules are the basic building blocks of life. Without them, our world as we know it would not exist.

In much the same way, freight railroads provide the foundation that enables the world’s top economy to thrive. For manufacturers and consumers, small and large businesses, energy companies and farmers, freight rail is the basic building block that allows a great sweep of economic activity to take place across the country.

From providing some of the highest-paying jobs in America to protecting the environment through fuel-efficient operations to delivering the raw materials and finished goods you rely on every day, U.S. freight railroads have a huge impact on our economy, global trade and modern life as we know it.
