In November 1868 Rogers delivered five identical coal-burning 4-4-0 steam locomotives (assigned Nos. 116–120) to the Union Pacific Railroad, which were subsequently placed into freight service in western Wyoming and Utah. Union Pacific No. 119 would gain fame on May 10, 1869, when it took part in the "Golden Spike" ceremony at Promontory, Utah, to celebrate the completion of the First Transcontinental Railroad. The unit was rebuilt in the early 1880s, and redesignated as road No. 343 in 1885. No. 119 was retired and sent to the scrapyard after nearly 35 years of service in April 1903. A full-scale, operating replica was completed in 1979, and now is part of an operational display at the Golden Spike National Historic Site.
