who signed the order to build the transcontinental railroad
First Transcontinental Railroad In February 1860, Iowa Representative Samuel Curtis introduced a bill to fund the railroad. It passed the House but died when it could not be reconciled with the Senate version due to opposition from southern states who wanted a southern route near the 42nd parallel.[30] Curtis tried and failed again in 1861. After the southern states seceded from the Union, the House of Representatives approved the bill on May 6, 1862, and the Senate on June 20. Lincoln signed the Pacific Railroad Act of 1862 into law on July 1. It authorized creation of two companies, the Central Pacific in the west and the Union Pacific in the mid-west, to build the railroad. The legislation called for building and operating a new railroad from the Missouri River at Council Bluffs, Iowa, west to Sacramento, California, and on to San Francisco Bay.[31] A second law to supplement the first was passed in 1864.[32]
