The train guard was attacked and knocked unconscious by an assailant who then stole his uniform coat. This impostor used the guard's clothes to move through the train undetected, posing as railway staff while helping orchestrate the escape attempt. The disguise allowed the accomplices to operate freely among the passengers.

Foreshadowing: The initial discovery of the opened door and snow being blown into the carriage signals that someone has already breached the train's security.

Foreshadowing: The growing danger and escalating tension build toward the power outage as the critical moment for the murder.

The power failure at the junction station was caused by the severe snowstorm. The harsh winter conditions knocked out the electrical supply, plunging the waiting room into darkness. This was not deliberately caused by the conspirators but rather the extreme weather that forced all passengers to shelter at the station.

Foreshadowing: The earlier reference to a fierce snowstorm establishes the environmental conditions that will later become critical to the plot.

During the final confrontation, it was revealed that Peterson's killer had accidentally shot the officer in the darkness while attempting to shoot Harding. In the chaotic exchange during the climax, the killer's aim was thrown off by the poor visibility and tension, resulting in Peterson being hit instead of his intended target. Both Peterson's killer and Harding end up dead.

Foreshadowing: The earlier accidental shooting of Peterson during the power outage sets up the revelation that the killer's marksmanship failed in the darkness.
