How did the U.S. government encourage the growth of the railroad industry in the late 1800s?

In the late 1800s, the U.S. government encouraged the growth of the railroad industry through significant land grants and financial incentives. The Pacific Railway Acts of 1862 and 1864 provided substantial land to railroad companies, facilitating the construction of transcontinental railroads. Additionally, the government offered loans and subsidies to support the expansion and modernization of rail infrastructure. This investment was crucial for promoting westward expansion and enhancing economic development across the nation.
