The railroad increased commerce by making shipping easier and cheaper.

It linked East and West, greatly cut travel time and freight costs, opened national markets for farm and manufactured goods, and stimulated industries (steel, coal, timber) and settlement. (There were also negative effects — e.g., corruption scandals like Crédit Mobilier and displacement of Native peoples — but the overall effect on U.S. commerce was a large increase.)
