author
Created by a railroad’s passenger department, this author name points to the promotional side of early Western train travel rather than a single individual. These books and pamphlets were made to spark curiosity about routes, scenery, and destinations served by Union Pacific.

Project Gutenberg lists Union Pacific Railroad Company. Passenger Department as a corporate author for travel and promotional works, including titles connected with the Overland Route. In other words, this is not a person’s byline but the publishing arm of the railroad’s passenger division, which produced material to attract travelers and shape how the American West was presented to the public.
Works credited this way were typically part guidebook, part advertisement, describing landscapes, rail journeys, and points of interest along Union Pacific lines. Because the available source in this search result is a catalog entry rather than a full biographical profile, specific historical details about the department itself are limited here, so it is best understood as an institutional author tied to the company’s passenger promotion efforts.
