If a train operator sees someone wave a green lantern, what should they do?

When a train operator sees someone waving a green lantern, it signifies a specific signal from railroad personnel. The correct response in this situation is to sound two horn blasts and proceed normally. This action indicates acknowledgment of the signal provided by the personnel on the ground, who may be indicating that the way is clear for the train to continue its route.

In the context of train operations, the green lantern is an important aspect of communication that ensures the safe movement of trains. By responding with horn blasts, the train operator is both affirming the signal and ensuring that other crew members or personnel are aware of the train's presence, thereby maintaining safety protocols.

Reducing speed or stopping the train is not typically warranted in response to a green lantern, as this signal does not point to an immediate danger or obstacle. Similarly, contacting the control center for clarification is unnecessary at this stage, as the signal has already been established by trained personnel on the ground. Thus, it is essential for train operators to be knowledgeable about these signals and respond appropriately to ensure seamless and safe train operations.
