If STOP is not indicated in the Stop column of the Form B track bulletin, may a train enter the limits of Form B without instructions?

The correct answer is that a train may not proceed into the limits of Form B if STOP is not indicated in the Stop column of the track bulletin. This is in line with safety protocols designed to ensure the safe operation of trains in areas where track work or other hazards may be present.

Form B track bulletins are crucial in providing instructions and restrictions for train movements within designated limits where work is performed. If a train were to enter the limits of Form B without express instructions or a STOP indication, it could potentially lead to dangerous situations, including collisions with work crews or equipment on the track.

The absence of a STOP indication clearly implies that there are rules in place that govern entry into those limits, emphasizing caution and the need for proper authority before any movement can occur. This ensures that all movements are carefully coordinated, and all personnel involved are aware of any work being conducted on the tracks. Thus, the protocol reinforces operational safety and adherence to established guidelines.
