Helen is mostly obsessing about trains on the wrong trail (or men on the wrong path — the path of misconduct, or crime).
And while chasing them she is capable of spectacular stunts.
When others are in PERIL, she is capable of HAZARDS.
The HAZARDS of Helen:
(episode 15) The Engineer's PERIL
Helen, the operator at Hobart, warns her friend Anna, the operator at Montville, that Tim Hudson, a notorious swindler, is headed for Montville. Anna later brings about Hudson's arrest when the man, posing as a minister, attempts to swindle the people of the town. Anna marries Tom Binfield, a locomotive engineer. Shortly afterwards, Hudson escapes from jail. The man secures a position as fireman on the railroad and is assigned to Tom's engine. Tom invites the convict to board at his home. Anna fails to recognize her husband's fireman when the man comes to live at the Binfield cottage. Hudson, however, is filled with an insane desire for revenge upon seeing Anna. An attempt to shoot her is unconsciously frustrated by her husband. The convict thereupon resolves to punish Anna through Tom. Hudson's opportunity comes the following day. Just before their train passes the Binfield cottage, the scoundrel strikes Tom over the head with a wrench. Believing his victim dead, Hudson leaps from the engine. Anna, however, sees Tom's body hanging from the locomotive cab. At frightful risk to her own life, the girl succeeds in saving her husband.
(episode 40) The Limited's PERIL
Wharton, trailing Red Leary and his gang, learns that the men intend to wreck the Limited. Curley, a fireman, is implicated. The crooks become aware of Wharton's presence and attack him. Helen comes to the detective's rescue with a revolver and captures one of the men. Undaunted, the rest of the gang plant dynamite in a culvert. Adair comes upon them just as they are in the act. The crooks capture the detective, bind him, and then place their victim so near the dynamite that the explosion will kill him. One of the desperadoes tries to capture Helen, but the girl flees and attempts to cross the drawbridge a short distance away. The crook overtakes her and the two battle as the draw is raised. Falling, they roll down the incline. Helen's assailant is stunned and the girl gains her freedom. The draw is lowered and the girl rushes back to rescue Wharton. Red Leary's men have connected the detonating charge to a push button which is placed on the track. Thus the Limited in passing over.
