RailARC was the brainchild of two avid railfans, Nathan Holmes and Michael Petersen. With a mutual interest in the Iowa Interstate railroad, the two started the Unofficial Iowa Interstate Photo Archive and Railfan's Guide while students at Iowa State University in Ames, IA. As this archive grew, so did their ambitions. It began with a desire to share their individual railroad photo archives with the public. Eventually, RailARC was conceived as a way to do this while also (eventually) providing a forum for others to share their photographs. After a semester's worth of work, the database software was written and the original RailARC was born in 2000. This site ran for a number of years with few problems, but also few updates, mainly since we both now had real jobs. However, after little bits of hacking here and there, a major overhaul was released in 2006 to update the site and add new features, resulting in the site you see here.

RailARC is intended to be an open forum for the exchange of high-quality railroad photography. Its main purpose is to provide a research database to assist historical researchers, modelers, and others interested in railroad equipment. As a research database, the focus of RailARC is not on defending copyrights and such, but instead to provide a public forum for sharing photographs.  For more information, please read the RailARC Usage Policy.
