Union Pacific Railroad built the line westward and the Central Pacific Railroad built the line eastward. The first transcontinental railroad basically connected the east and the west of the United States.

Central Pacific Railroad merged with Southern Pacific in 1885 and then Union Pacific bought Southern Pacific in 1996. Union Pacific still operates much of the rail from Central Pacific Railroad and Southern Pacific Railroad.

The two companies in charge of building the transcontinental railroad were the Union Pacific and the Central Pacific. The Union Pacific worked from east to west, and the Central Pacific worked from west to east. Both companies stopped at Promontory Point, Utah, where the last golden spikes was hammered in to commemorate the building of the railroad.
