Winslow's railroad history: the 1882 founding and Santa Fe division point years
Winslow was founded in 1882 as the Atchison, Topeka and Santa Fe Railway extended its main line west from New Mexico into Arizona Territory. The site was selected as a division point — a location with major railroad infrastructure where train crews changed, locomotives were maintained, and railroad operations were divided into smaller segments. Division points required substantial labor forces and substantial physical infrastructure, and small towns at division points typically grew rapidly through the late 19th and early 20th centuries as railroad workers, their families, and supporting businesses concentrated in the area.
By 1900 Winslow had developed substantial railroad infrastructure including a roundhouse for locomotive servicing, a large rail yard for freight assembly, division administrative offices, and housing for railroad crews. The Santa Fe Railway was one of the largest employers in northern Arizona, and Winslow's economy was substantially dependent on railroad operations across its first several decades. The town's commercial district along Second Street and Kinsley Avenue developed to serve railroad workers and their families.
The railroad era continued through the early and mid 20th century with substantial scale. Winslow remained an important Santa Fe division point through World War II and into the post-war years. The decline of passenger rail in the 1950s and 1960s reduced the town's railroad-dependent economy, though freight operations continued and continue to the present day. The original 1880s-era railroad infrastructure has been largely replaced or demolished, but the historic downtown commercial district that developed to serve railroad workers remains substantially intact and is the area most Route 66 tourists explore today.
