No. 119 was stationed in Ogden, Utah, when a call came from Thomas C. Durant, traveling to Promontory, who needed an engine. Similar to Leland Stanford and the Jupiter, previous misfortunes allowed No. 119 to take her place in history. Durant, the vice president of the Union Pacific Railroad was traveling on the so-called Durant Special for the ceremony at Promontory. A swollen river had washed away some supports to the Devil's Gate Bridge. Durant's engineer refused to take the current engine across but did consent to nudge the lighter passenger cars across the bridge. The bridge held, the cars made it across but Durant and his entourage were left without an engine. Durant's plight was answered when No. 119 was sent from Ogden to take the Durant Special the short distance to Promontory where it came nose to nose with the Central Pacific's Jupiter.
In Andrew J. Russell's famous photograph of the Meeting of the Lines, No. 119 is seen on the right with its engineer, Sam Bradford, leaning off the pilot holding a bottle of champagne up to Jupiter engineer George Booth. Bradford and Booth would later break a bottle of champagne over the other's locomotive in celebration.
The First Transcontinental Railroad, the National Park Service's Golden Spike site at Promontory, Utah, had exhibited representations of the 119 and Jupiter on a portion of restored trackage where the original ceremony was held. In this instance, the 119 was portrayed by the Virginia and Truckee Railroad's Dayton locomotive, (which is ironic because The Dayton was built by the Central Pacific Railroad's shops in Sacramento) and was displayed here until it and the Jupiter, which was portrayed by that railroad's Inyo locomotive, were sold to the state of Nevada in 1974.
In 1975, the National Park Service embarked on a project to reproduce the Union Pacific No. 119 and Central Pacific Jupiter exactly as they appeared in 1869. Initially, the Park Service had approached Walt Disney Studios, who had previously built two steam engines from scratch for their Disneyland park's railroad, for the project. Disney declined, but recommended Chadwell O'Connor's firm, the O'Connor Engineering Laboratories in Costa Mesa, CA, for the task. Over 700 detailed engineering drawings were recreated, based almost entirely on the photographs taken of the engines during the ceremony, as the original drawings have not been preserved. Disney animator and steam engine owner Ward Kimball did color matching and original artwork for the Jupiter and No. 119. The replicas began operating on May 10, 1979, and continue to make demonstration runs.
