When in the cab with the engineer, a conductor must do what in regards to calling out signals?

• A. They must communicate to each other in a clear manner the name of each signal as soon as it becomes clearly visible
• B. They must call out signals only when the engineer prompts
• C. They must record signals in a log but not verbalize them
• D. They must avoid verbal communication altogether

Answer: (A)

The essential idea is to keep the engineer and conductor in perfect sync by verbally identifying signals as they appear. In the cab, the conductor must call out the name of each signal as soon as it is clearly visible. This immediate, clear communication lets the engineer know exactly which signal is in effect and what it means for the train’s movement, even if the view is partial or conditions make reading the signal tricky.

This proactive calling out prevents misreads and miscommunications, which are safety risks in rail operations. Waiting for the engineer to prompt or relying on a log alone doesn’t provide the real-time confirmation needed for safe operation, and avoiding verbal communication defeats the purpose of coordinating signal aspects.
