Treynor

Treynor is a city in Pottawattamie County, Iowa, United States. The population was 919 as of the 2010 census and was estimated by the Census Bureau to be 957 in 2016.

Treynor began east of Council Bluffs in the late 1880s with the establishment of Fritz Eyberg’s General Store, August Olderog’s dance hall and saloon, and St Paul’s German Evangelical Church. The vicinity east of Middle Silver Creek had previously been known for its number of wolves. Local German immigrant farmers referred to the settlement as Four Corners or High Five, a popular card name, until the post office opened in the early 1890s as Treynor, named after the recently deceased Council Bluffs postmaster. By the time the town was incorporated in 1905 it included two general stores, two saloons, a furniture/implement house, a livery stable, several blacksmith shops, and the Treynor State Bank. In 1911 the community got its own railroad with the opening of the Iowa & Omaha Shortline which ran 12 miles to Mineola on the Wabash Railroad line southeast of Council Bluffs. The line was unprofitable and ended operations after five years. The Great Depression closed down the Treynor State Bank while improvements began on the “Short-line” Road from Treynor to Council Bluffs that is now Iowa Highway 92. An Air Force radar base operated just outside town during the early years of the Cold War.
