Explanation:

The First Transcontinental Railroad in the United States was a railroad line, built between 1863 and 1869 by the Central Pacific and Union Pacific companies, which connected Council Bluffs (Iowa) and Omaha (Nebraska) to Sacramento (California) and the Pacific Ocean in Oakland (California). Linking with the existing rail network to the east it connected, in fact, the coast of the Atlantic Ocean with the one of the Pacific for the first time with railroad. The line was popularly called Overland Route and was in service until the end of 1962. Coming into service on May 10, 1869 with the placement of the symbolic golden spike in Promontory (Utah), this route established a transcontinental mechanized transport system that revolutionized demography and the economy from the Far West of the United States.
