What were the names of the two railroad companies that completed the Transcontinental Railroad?

Question

Who were they?

Answer 1

The Central Pacific (from west) and Union Pacific (from east). They met up on May 10, 1869 at Promontory, Utah.

The Central Pacific Railroad was the California-to-Utah portion of the First Transcontinental Railroad in North America. Many proposals to build a transcontinenal failed because of the disputes over slavery in Washington; with the secession of the South, the modernizers in the Republican party took over Congress and passed the necessary legislation and subsidies. It was planned by Theodore Judah, authorized by Congress in 1862 and financed and built through "The Big Four" (who also called themselves "The Associates"), who were Sacramento, California businessmen Leland Stanford, Collis Huntington, Charles Crocker, and Mark Hopkins.

The Union Pacific Railroad was incorporated on July 1, 1862 in the wake of the Pacific Railroad Act of 1862. Under the guidance of its dominant stockholder Thomas C. Durant the first rails were laid in Omaha, Nebraska. They were part of the railroads that came together at Promontory Summit, Utah, in 1869 as the first transcontinental railroad in North America.
