The Pacific Railroad Acts of 1862-1865 chartered the Central Pacific and Union Pacific Railroads to build the transcontinental railroad. The railroads received loans of $16,000-$48,000 per mile of track laid and 10 square miles of land for each mile built. The railroad was completed in 1869, connecting the eastern and western United States by rail and enabling the transport of cattle from Texas to markets in the central plains. Ranchers began fencing in their land with barbed wire and raising more docile breeds of cattle as long cattle drives became impractical. Farming technologies like steel plows, mechanical reapers, and grain drills helped make farming the prairie lands viable.
