Union Pacific Railroad Museum

Just across the river from Omaha in the cute little downtown area of Council Bluffs, IA, this highly interactive museum tells the story of the world's most profitable railroad (it's headquartered in Omaha) and the company that rammed the transcontinental line west from here in the 1860s. The three levels of exhibits offer a nostalgia-filled ode to train travel and how it forever changed America.
