Which single scenario would require the train crew to call out Emergency over the radio?

• A. Severe slack action while stopping
• B. The train goes into emergency
• C. A routine stop with no issues
• D. A minor delay

Answer: (B)

Calling Emergency on the radio is required whenever there is an urgent, potentially dangerous situation affecting train safety. The scenario where the train has activated its emergency brakes signals a real safety incident that needs immediate attention from dispatch and other crews. An Emergency radio call quickly alerts everyone that the train cannot continue under normal conditions and may need assistance, track protection, or recovery actions. The other situations — severe slack action, routine stop, or a minor delay — can be managed through normal communications and do not by themselves indicate an immediate threat that requires an emergency broadcast.
