What must employees in the track area be alert for?

Employees in the track area must be particularly vigilant about the movement of trains in either direction. Trains can approach unexpectedly and often travel at high speeds, making it critically important for employees to be aware of their surroundings. Awareness of train movement ensures not only the safety of the employees but also the safe operation of the trains themselves.

While unexpected weather changes, audio signals from machinery, and nearby maintenance personnel are all important factors to consider in a work environment, the direct and immediate risk posed by moving trains significantly outweighs these other concerns in this specific context. Thus, focusing on train movement is essential for maintaining safety protocols and preventing accidents on the tracks.
