The 1926 Santa Fe depot and the railway-era history
The Santa Fe depot building that houses the visitor center is itself a substantial piece of Flagstaff history — a 1926 brick-and-stone passenger station built by the Atchison, Topeka and Santa Fe Railway to replace an earlier wood-frame depot that had served Flagstaff since the original 1882 railroad construction through the region. The 1926 depot was part of a broader Santa Fe Railway investment in its passenger-rail infrastructure across the American Southwest during the prosperous 1920s, and the building's architecture reflects the Santa Fe's signature mission-revival-influenced style that characterized many of its depots from this era.
The depot served as the primary railroad gateway to Flagstaff for several decades, with the Santa Fe Railway's prestigious passenger trains (including the original Super Chief and the El Capitan, which ran daily between Chicago and Los Angeles during the streamliner era) stopping at the depot for passenger boarding, mail and baggage handling, and engine servicing. Through the 1930s and 1940s, the depot was one of the busiest passenger-rail stops on the Santa Fe's transcontinental mainline, with thousands of passengers using the facility annually for travel to Grand Canyon (via the Grand Canyon Railway connection at Williams), to Hollywood (the Santa Fe was the standard route for Hollywood film stars traveling between Los Angeles and East Coast destinations), and for general transcontinental travel.
Passenger-rail traffic declined substantially after the 1950s with the rise of commercial aviation and the Interstate highway system, and the depot's role narrowed significantly. The Burlington Northern Santa Fe (the successor to the original Santa Fe Railway following multiple mergers) continued to operate freight traffic through the mainline, and Amtrak took over the remaining passenger service in 1971. The daily Amtrak Southwest Chief (the modern successor to the original Super Chief) continues to stop at the depot today, providing one daily eastbound and one daily westbound passenger train service.
