The Union Pacific Railroad Photographs depict the Union Pacific Railroad Company's tracks, depots, locomotives, and stations in Southern Nevada and Southern California from 1904 to 1973. The photographs primarily depict Union Pacific officials in Las Vegas, Nevada, construction of Boulder City, Nevada and the Hoover (Boulder) Dam, hotels and casinos in Las Vegas, and the aftermath of flooding in 1938 that damaged Union Pacific tracks.
