The Bridge of Danger (1916)

The new superintendent's first order on taking the post eliminates the men whom he terms old, which costs "Pop" Bates his job as Helen's relief operator. His next declaration is that active railroad work is no place for women, and Helen is also dropped from the service. While Helen is breaking the news to Bob Bates, the new superintendent is hustling about the road yard speeding up the work. "Put more snap into your switching," he tells the men. A minute later, while he is making an inspection inside a boxcar with defective air brakes, a switching engine rams the car. The force of the impact, heightened by the recent orders, throws the superintendent to the floor stunned, and starts the car on the down grade. In the few moments it is speeding along the road and there is consternation among the men for a washout down the road means that it is headed to certain destruction.
