In the 119 episodes that compose the long series of her adventures, Helen is a plucky telegraph operator who has willingly charged hersef with the task of looking after the safety of the railroad, intervening at every time to protect passenger wagons or freight trains from impending disasters caused by bands of criminals. Launched by Helen Holmes with the help of her husband, director J. P McGowan, the character of Helen was extremely popular between 1914 -1917. Screenwriter and co-director of many episodes of this and other series and serials, Holmes once declared that only by writing her own scripts she could really be certain she would have a chance to perform the thrilling stunts that were her passion. After she left Kalem to found with her husband an independent company, the role was given to her stand-in, Helen Gibson, a rodeo artist who had already been active as a stunt woman in Hollywood. With Gibson’s excellent acrobatic skills and lively presence, the new Helen was quite successful in replacing the original, while Holmes went on recreating her character in several more films and serials.
