After the American Civil War, railroad construction linked the areas of the county, giving rise to new towns, and gave access to other markets. In 1868 the railroad reached Afton, Iowa, and the next year Creston, the county seat, was made a division point. The railroad built service facilities there, a roundhouse and related structures. The railroad brought immigrants and migrants to the area, who were attracted to the fertile soil as farmland. Immigrants came from across central and eastern Europe, as well as from eastern states of the US. The Burlington Northern Santa Fe Railroad (BNSF) continues to be important in the area, serving as the chief network for hauling grain and coal. Over the years, it drew workers from industrial cities such as Chicago to Creston.
