Welcome Iowa Interstate Enthusiasts! The Unofficial Iowa Interstate Photo Archive and Railfan's Guide is dedicated to covering the past and present of Iowa Interstate (IAIS), one of the older and more successful of America's regional railroad spin-offs.

Born from the ashes of the Chicago, Rock Island & Pacific in 1984, Iowa Interstate operates about 500 miles of railroad, centered around the ex-CRIP main from Bureau, IL, west through the Quad Cities and Des Moines into Council Bluffs, IA. Additionally, they reach eastward to Blue Island, IL, via CSX and Metra trackage rights, and south to Peoria, IL, as well as operating several small branches off the main line. This site is meant to assist already avid IAIS enthusiasts, encourage new ones, and provide information to those just dropping in for a visit.
