What is the preferred method to inform another crew about a signal?

The preferred method for informing another crew about a signal is by maintaining the integrity and security of signal information. It is crucial that crews do not share or relay specific signal indications to others, as this could lead to misunderstandings or unsafe situations. Each crew is responsible for interpreting the signals they encounter based on their own situation and context. Consequently, allowing a crew to communicate signal information could compromise operational safety.

In a railroad environment, safety is paramount, and protocols are in place that dictate the communication methods to ensure clear, unambiguous exchanges of information. Relying on individual crews to interpret and act on the signals they see maintains this safety standard and prevents miscommunication that could arise from sharing signal details, which might not be applicable in different contexts. Thus, the correct response emphasizes the importance of individual crew accountability and safety in signal recognition and interpretation.
