As the United States began the most deadly conflict in its history, the American Civil War, it was also laying the groundwork for one of its greatest achievements in transportation. The First Transcontinental Railroad, approved by Congress in the midst of war, helped connect the country in ways never before possible. Americans could travel from coast to coast with speed, changing how Americans lived, traded, and communicated while disrupting ways of life practiced for centuries by Native American populations. The coast-to-coast railroad was the result of the work of thousands of Americans, many of whom were Chinese immigrant laborers who worked under discriminatory pressures and for lower wages than their Irish counterparts. These laborers braved incredibly harsh conditions to lay thousands of miles of track. That track—the work of two railroad companies competing to lay the most miles from opposite directions—came together with the famous Golden Spike at Promontory Summit in Utah on May 10, 1869. This exhibition explores the construction of the first Transcontinental Railroad and its impact on American westward expansion. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Professor Krystyna Matusiak's course "Digital Libraries" in the Library and Information Science program at the University of Denver: Jenifer Fisher, Benjamin Hall, Nick Iwanicki, Cheyenne Jansdatter, Sarah McDonnell, Timothy Morris and Allan Van Hoye.

From the earliest days of settlement and migration, the people of North America have relied on maps and mapping to understand their environment and place within it. Maps have helped Americans prospect investments, comprehend war, and plan leisure in places unknown. As Americans have used maps to explore the U.S., capitalize on its resources, and displace its Native peoples, maps have shaped American cultural ideas about travel, place, and ownership. This exhibit explores the cultural and historic impact of mapping through four specific moments in American history: migration along the Oregon Trail, the rise of the lumber industry, the Civil War, and the popularization of the automobile and individual tourism. It concludes with a look at maps in the age of computers, the Internet, and beyond. These moments demonstrate the influence maps have had over how Americans imagine, exploit, and interact with national geographies and local places. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students in Professor Helene Williams's capstone course at the Information School at the University of Washington: Greg Bem, Kili Bergau, Emily Felt, and Jessica Blanchard. Additional revisions and selections made by Greg Bem.

This collection uses primary sources to explore the steam engine and transportation in the nineteenth century. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

In this unit, students learn the very basics of navigation, including the different kinds of navigation and their purposes. The concepts of relative and absolute location, latitude, longitude and cardinal directions are explored, as well as the use and principles of maps and a compass. Students discover the history of navigation and learn the importance of math and how it ties into navigational techniques. Understanding how trilateration can determine one's location leads to a lesson on the global positioning system and how to use a GPS receiver. The unit concludes with an overview of orbits and spacecraft trajectories from Earth to other planets.

Students apply their knowledge about mountains and rocks to transportation engineering, with the task of developing a model mountain tunnel that simulates the principles behind real-life engineering design. Student teams design and create model tunnels through a clay mountain, working within design constraints and testing for success; the tunnels must meet specific design requirements and withstand a certain load.
