Ceremonial spike driven in a US Railroad

The golden spike is the ceremonial 17.6-karat gold spike driven to mark the completion of the first transcontinental railroad across the United States. It was driven by Leland Stanford to connect the Central Pacific Railroad from Sacramento and the Union Pacific Railroad from Omaha on May 10, 1869, at Promontory Summit, Utah Territory. The spike is now displayed in the Cantor Arts Center at Stanford University.
