The Solano was a large railroad ferry, built as a reinforced paddle steamer with independently powered sidewheels by the Central Pacific Railroad, that carried entire trains across the Carquinez Strait between Benicia and Port Costa in California, daily for 51 years from 1879 to 1930. When launched, the Solano was the largest ferry of its kind in the world, a record held for 35 years until 1914 when she was joined by her sister ship, the Contra Costa, which was 13 feet longer.
