The Broken Train (1915)

Helen spotting two jewel robbers sever the telegraph wires and hop onto a passing freight, jumps into a racing auto and takes off in pursuit. In the meantime, the freight's brakes fail, and the train breaks in two. Helen, on a road parallel to the tracks, leaps onto a flat car, runs forward, informs the train crew what has happened, and captures the crooks.
