Rock Island Trail is proof enough that Republic could turn out an "A" western as well as any of the "majors." This saga of pioneer railroading stars Forrest Tucker as Reed Loomis, a visionary railman who dreams of the day that trains will run from coast to coast. During his own efforts to make this dream come true, Loomis must face the formidable opposition of steamboat operator Kirby Morrow (Bruce Cabot). Another ongoing problem is lack of funds: fortunately, Loomis is in love with Constance Strong (Adele Mara), who happens to be a banker's daughter. Longtime Republic leading-lady Adrian Booth plays Aleeta, an Indian princess who has a yen for Loomis -- meaning, of course, that she probably won't survive to the end of the film. The film's climax is an all-out action orgy in the grand Republic tradition.
