The ubiquitous J. P. McGowan warmed the director's chair for Red Signals. Though onetime matinee idol Earle Williams is starred, the film's real protagonist is Wallace McDonald, cast as a dishevelled hobo. When a series of train wrecks occur, railroad superintendent Williams is held responsible, but the real culprit is a crooked foreman who lusts after Williams' job. All of this is proven in due time by the superintendent's indigent brother McDonald -- who turns out to be a railroad detective in disguise. Some laughs are provided by Billy Franey and Frank Rice, usually cast as cowboy sidekicks but here playing McDonald's hobo companions.
