A Boy at the Throttle Filming Locations

Climbing into a cab of a freight engine, Bobbie Layson, the son of a station pulls the throttle open. The alarm goes out and Helen, stationed at Lone Point, is ordered to derail the runaway and thus prevent it from running head-on into the approaching passenger train. Fearing for his son's life, Layson phones Helen and implores her not to send the engine into the ditch. Outside the station a small truck suggests a way out of her dilemma. Leaving the derail open, Helen gets the car on the track and speeds down the grade to the end of the siding, where she opens the switch and flags the passenger train. Her warning causes the engineer to sidetrack his train. This done, Helen speeds to the Melius Bridge and reaches it before the runaway train. Climbing to the topmost girder she then hangs suspended by a rope and as the onrushing train roars across the bridge she drops to the top of a freight car and in a few seconds the runaway is brought to a stop.
