The Union Pacific Railroad Depot is a one-story brick and granite transportation structure with Richardsonian Romanesque elements constructed in 1901 with a baggage and telegraph addition to the west side (1901-1903) and an Eating House addition to the east side (1903-1912). The Depot is representative of the influence of the railroad and its transportation connections as related to the development and growth of Rawlins. The railroad served as a reason for settlement and its transportation links provided support for the development of other industries and expansion of the city.
