The transcontinental railroad was a big step in the industrial revolution. This railroad also known as the Pacific Railroad is what first connected the east United States to the west. Before the railroad was built, people had to travel either by wagon or even by boat to travel across the United States. The railroad provided a safe way for traveling. This also played a big role in expanding the US and allowing for settling in the West. It’s interesting to look back at history and see how something that we see as easy nowadays (traveling), first begin.
