In this online exhibition from the Smithsonian's National Museum of American History, students will discover how the completion of the network of transcontinental railroads in the 19th century changed American agricultural practices. Railways that linked farms to the wider commercial world made it possible to ship food farther and faster before it spoiled. Vast wheat fields supplied flour for people around the world. Trains carried cattle and hogs to central stockyards and refrigerated railcars carried meat, fruits and vegetables to cities across the country year-round.
