Which of the following scenarios would require emergency callouts?

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

Answer: (D)

Emergency callouts are needed whenever a train enters an emergency state and an immediate, heightened response is required. When the train goes into emergency, it signals a sudden, unsafe condition that demands fast coordination with the appropriate control and response teams. That makes this scenario the clear case for calling out emergency responders right away. The other situations—severe slack action during braking, a routine stop with no issues, or a minor delay—do not by themselves constitute an emergency under standard operating procedures. They may require inspection or standard reporting, but they don’t trigger the urgent emergency protocol.
