Historical railroads played a crucial role in the development of transportation and commerce. They emerged in the early 19th century, connecting cities and regions, which facilitated the movement of goods and people. The invention of the steam locomotive, such as those designed by George Stephenson, revolutionized travel and trade, making it faster and more efficient. In the United States, the completion of the Transcontinental Railroad in 1869 marked a significant milestone, linking the eastern and western parts of the country. This expansion not only boosted the economy but also encouraged westward migration, shaping the nation’s growth and development.
