1. Expanding Population and Cities: The population in the western states was rapidly increasing, fueled by the discovery of gold, silver, and other precious metals, as well as the availability of fertile lands suitable for agriculture. This population growth created a strong demand for transportation infrastructure to connect people and goods to established markets in the East.
2. Land Policy: The federal government's land policy, particularly the Homestead Act of 1862 and the Morrill Land-Grant Acts, encouraged settlers to move westward by offering them free or low-cost land. The expansion of settlements and agricultural activities, coupled with the presence of valuable natural resources, made railroad construction essential to transport agricultural products, minerals, and other goods from the West to markets in the East and beyond.
3. Federal Subsidies and Incentives: The federal government played a significant role in encouraging railroad construction through subsidies, land grants, and financial incentives. The Pacific Railway Acts of 1862 and 1864, also known as the Union Pacific and Central Pacific Railroad Acts, granted massive amounts of land to railroad companies along the routes they were building and offered favorable financial terms to encourage private investment in railroad construction. These incentives greatly reduced the financial risks and made railroad building in the West more feasible.
4. Agricultural Production and Transportation: With vast stretches of fertile land in the West, especially in the Great Plains region, railroad expansion was essential to transport the increasing agricultural production to markets. The construction of transcontinental railroads, such as the Union Pacific, facilitated the efficient movement of agricultural products from the Midwest and the West Coast, revolutionizing the agricultural industry.
5. Mineral and Natural Resource Extraction: The Western region was rich in mineral deposits, including gold, silver, copper, and lead. Railroads played a vital role in transporting these valuable resources from mining areas to smelters, processing facilities, and markets. Additionally, the abundance of natural resources, such as timber and coal, fueled the growth of industries in the Western states and increased the need for reliable transportation infrastructure.
6. Military and Strategic Importance: The construction of railroads in the West also had significant strategic and military importance. Rapid troop and supply movements were crucial during the American Indian Wars and various military campaigns in the region. Railroads were essential in connecting military posts and facilitating effective communication and logistics.
By fulfilling these diverse economic, social, and strategic needs, railroad expansion in the western part of the United States after 1870 played a transformative role in shaping the nation's economy, settlement patterns, and overall development.
