When the First Tanscontinental railroad was built, all the smoke came to where the Native Americans lived. They called the train the 'Iron Horse".
The Transcontinental Railroad connected the east coast of the United States with the west coast. Previous to the completion of the railroad the only way to cover the distance was on horseback which could take several months.
It is often argued that the transcontinental railroad increased the national GNP, but an economic study shows that the GNP would have remained the same without the railroad, but it would have been concentrated in the East.
The construction of the Transcontinental Railroad in the United States began in 1863 and was completed on May 10, 1869. The railroad was built to connect the eastern and western parts of the country, facilitating trade and travel. The final spike, known as the "Golden Spike," was driven at Promontory Summit in Utah, marking the completion of this monumental project.
The First Transcontinental Railroad opened for traffic on May 10, 1869.
