On May 10, in anticipation of the ceremony, Union Pacific No. 119 and Central Pacific No. 60 (better known as the Jupiter) locomotives were drawn up face-to-face on Promontory Summit in the Utah Territory. It is unknown how many people attended the event; estimates run from as low as 500 to as many as 3,000; government and railroad officials and track workers were present to witness the event. Completing the last link in the Transcontinental Railroad with a spike of gold was the brainchild of David Hewes, a San Francisco financier and contractor. A special tie of polished California laurel was chosen to complete the line where the spike would be driven. The ceremony was originally to be held on May 8, 1869 (the date actually engraved on the spike), but it was postponed two days because of bad weather and a labor dispute that delayed the arrival of the Union Pacific side of the rail line. The ceremonial final spike was driven by Leland Stanford to join the rails of the First Transcontinental Railroad across the United States connecting the Central Pacific and Union Pacific railroads.
