Union Pacific 4-4-0 No. 119 was one of two locomotives that participated in the 1869 Golden Spike cememony at Promontory Point, Utah, marking the completion of the transcontinental railroad. The other locomotive was the Central Pacific's Jupiter. Both of these historic locomotives were scrapped, so twentieth-century reenactments of the ceremony — such as that during the "Wheels-a-Rolling" pageant — had to use other locomotives disguised as the original participants. At the 1939 New York World's Fair the stand-in for No. 119 was Chicago, Burlington & Quincy No. 35. Comparing a postcard view of No. 35 from the 1933 "Century of Progress" Exposition it appears that the same locomotive, minus the fake balloon stack, played the role of No. 119 at the Chicago Railroad Fair.
