The transcontinental railroad was built by the Central Pacific and Union Pacific Railroad Companies. Construction began in 1863. The two companies started on opposite ends of the country and built toward each other for seven years. During that time, both companies overcame many struggles. There were weather delays, and holes had to be cut through mountains. When finished, the railroad was 1,912 miles long and connected the country from coast to coast. Transporting passengers and goods was faster, easier, and less expensive by train.
