There were 2,000 miles of track in 1850. There were 80,000 miles of track by 1877. Crossing the wilderness, the railroads changed the ways Americans thought and lived.In 1830, America’s first steam locomotive made its first appearance. Over the next 2 decades, railroad tracks linked many cities on the east coast. There were 9,000 miles of track that had been laid on the east of the Missouri River by 1850.In the same period, the first settlers started to move westward across the United States. It tended to rise dramatically in California, after the discovery of gold. In 1862, the Pacific Railroad Act certified the Central Pacific, and the Union Pacific Railroad Companies. Before the building of the Transcontinental Railroad, it cost 1,000 dollars to travel across the country. The rates of the bill, Central Pacific Railroad Company will start building in Sacramento, California. They will continue to build east across the Sierra Nevada. East of the Missouri River, the Union Pacific Railroads was going to be built. The two lines would meet up in the middle. The companies will receive 6,400 acres of land.The amount they will receive, will double the amount. In the beginning, the building of the transcontinental railroad was in charge of a competition between the two companies competing. In Omaha, Dr. Thomas Durant has badly achieved a supervising interest in the Union Pacific Railroad Company. In 1865, Charles Crocker was in charge of the construction happening in the Central Pacific, while he was struggling with saving workers. They began hiring Chinese workers. By that time, 50,000 Chinese colonist were living on the West Coast. Many having to arrive when the Gold Rush was happening. This was questionable at the time. The Chinese were considered a less chase, due to common racism. The Chinese colonist proved to be tireless workers, and Crocker hired more of them. There were 14,000 colonist that were striving under brutal working conditions in Sierra, Nevada in 1867. The railroad was first advanced in Great Britain. A man named George Stephenson strongly applied the steam technology of the day, and created the world’s first successful locomotive. Robert Fogel, among others, tried to measure the impact of transportation innovations on American development using tools of new economic history and concluded that the contribution of railroads was not as crucial as some had maintained. On May 10, 1869, the two tracks met in Promontory Summit, Utah. The Central Pacific Railroad Company had built a track from Sacramento, California for 690 miles, and the Union Pacific Railroad company had laid track for 1,086 miles from Omaha, Nebraska. The transcontinental railroad was completed with a golden spike. The most important people that were involved were, Theodore Judah, Grenville Dodge, Abraham Lincoln, Collis P. Huntington, Thomas C. Durant Leland Stanford, Oakes Ames, and Charles Crocker.
