The Girl on the Trestle

A wagon load of powder explodes, destroying the railroad trestle under which it is passing; Helen, knowing that a passenger train is due within a few minutes, climbs aboard a freight car which coasts down a steep grade near the trestle. As it nears the structure, she applies the brakes, leaps to the ground, crawls across the burning trestle

The Broken Train

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.

Helen smashes a hole through the side, braves the flames, crawls into the car, rescues Jim and drags him to safety. But her heroism is too late; Jim dies in her arms.
