The two railroad companies involved in the transcontinental  railroad were the Union Pacific and the Central Pacific. They  completed the track on May 10, 1869 at Promontoryâ¦ Summit, Utah.
Five years later, in 1869, another national railroad company, the Union Pacific, completed the country's first transcontinental railroad line. This was great for the development of the Midwest, Southwest, and California, but did little to promote the growth of the Pacific Northwest. The Northern Pacific's land grant stipulated that the company complete its transcontinental line by July 4, 1876.
