In the 19th Century, railroads were a form of transportation that changed the world. Transcontinental Railroads looks at the sweeping changes made to society and the challenges created by the building and running of these railroads in North America. Readers will be encouraged to critically analyze source material on why the railroads were built, who built them, and how they changed the movement of people and products. Topics include settlement and nation-building, as well as who gained through railroad building - and who lost. Teacher's guide available.
