You watched as the population of the frontier grew quickly. The Burlingame Treaty of 1868 led to a rise in Chinese immigration. Over 12,000 Chinese workers joined the Central Pacific railroad, making up more than 90% of its workforce. The labor shortage in the 1860s meant that railroad companies hired workers from many backgrounds, even when laws and discrimination made it difficult.
Railroads Shaping Decisions
You noticed that railroads did more than just move people. They shaped where and how people settled. Railroad companies received land grants from the government. These companies sold land to settlers and advertised the benefits of moving west. You could buy land near the tracks and start a new life.
The transformation of the Plains showed the power of this system. Kansas grew from about 10,000 farms in 1860 to 239,000 by 1880. This growth happened because railroads and land grants made it easier for you to reach and settle in the West. The companies built roads and stations, turning empty land into busy towns.
You saw that railroads offered more than transportation. They gave you access to markets and supplies. Farmers near Colfax, Washington, wanted railroads because they needed a way to sell crops and buy goods. One woman wrote that a railroad connection would bring big profits. The arrival of railroads let you send perishable goods to distant cities and buy modern products from far away.
Farmers in new areas needed transportation to succeed.
Families moved west for the chance to earn more money and improve their lives.
Railroads brought goods and services that made life on the frontier easier.
Railroads transformed the West by naming and renaming places. You saw new towns appear along the tracks, often named by railroad builders. This helped create a sense of place and encouraged more settlement in the west.
Railroads also changed the makeup of communities. The presence of transportation routes led to the growth of immigrant neighborhoods. The roads of steel connected people from different backgrounds. You could see Chinese, Irish, and European immigrants living and working together in new towns. The expansion of railroads and steam locomotives brought people to places like California, where they built farms, ranches, and cities.
The idea of manifest destiny inspired many Americans to move west. You believed that the nation should stretch from coast to coast. Railroads made this dream possible by providing the infrastructure needed for expansion and development. The roads of steel turned the frontier into a land of opportunity.
