How did the transcontinental railroad affect the nation?

Answer 1

The transcontinental railroad, completed in 1869, revolutionized transportation and communication across the United States, significantly reducing travel time and costs. It facilitated westward expansion, enabling the movement of settlers, goods, and resources, and fostering economic growth in previously isolated regions. Additionally, it helped unify the nation by connecting the East and West, promoting trade and cultural exchange, while also contributing to the displacement of Native American communities and altering their way of life.
