Which sea was crossed by the Polynesian voyagers to settle Hawaii?

The Central Pacific Railroad (CPRR) was a rail company chartered by U.S. Congress in 1862 to build a railroad eastwards from Sacramento, California, to complete most of the western part of the "First transcontinental railroad" in North America. Incorporated in 1861, CPRR ceased independent operations in 1885 when the railroad was leased to the Southern Pacific Railroad Company. Its assets were formally merged into Southern Pacific in 1959.
