The Transcontinental Railroad

Pacific Railway Act of 1862

  • The Pacific Railway Act authorized the construction of a transcontinental railroad

    • This would create a direct connection across the country to stimulate economic growth

  • The federal government supplied financial assistance in the forms of funds and land grants to railroad companies to encourage the project

  • Construction and key players included:

    • Union Pacific Railroad

      • Starting at Omaha, Nebraska 

      • Worked westward

      • The workforce consisted of Irish, German, and Italian immigrants

    • Central Pacific Railroad 

      • Starting at Sacramento, California

      • Worked eastward

      • The workforce consisted of immigrants from China, who faced harsh working conditions and discrimination

  • To complete the transcontinental railroad, the two railroads met at Promontory Point, Utah in May 1869

    • The final connection was symbolized by a golden spike, marking the completion

  • The transcontinental railroad set a precedent for future infrastructure development

  • More transcontinental railroads would be built in the coming decades, further enhancing connectivity and national economic growth
