Iowa Falls once had an Illinois Central Railroad (IC) mainline, a Chicago, Rock Island & Pacific Railroad (Rock Island) mainline, a Rock Island secondary line and a Chicago & North Western Railway (C&NW) branch line. Today, the former IC is owned by Canadian National Railway, while Union Pacific Railroad owns the former Rock Island mainline and the C&NW line. The former Rock Island secondary line and the C&NW line south of the city have both been abandoned.
