The group largely responsible for funding the building of the railroad system in the U.S. was the federal government, particularly through the passage of several acts by Congress in the 19th century. One crucial legislation was the Pacific Railroad Acts of 1862 and 1864, which authorized the construction of the First Transcontinental Railroad. These acts provided federal support in the form of land grants and loans to the railroad companies.
