The Sacramento Valley Railroad (SVRR) was incorporated on August 4, 1852, the first transit railroad company incorporated in California. Construction did not begin until February 1855 because of financial and right of way issues, and its first train operated on February 22, 1856. Although the oldest working railroad in the state was the Arcata and Mad River Railroad, first operational in December 15, 1854, the Sacramento Valley Railroad was the West's pioneering incorporated railroad, forerunner to the Central Pacific.
