Which device is used on the lead locomotive to monitor operator alertness and may trigger a penalty brake if not responded?

• A. Electronic Alertness Control Device (alerter)
• B. Speedometer
• C. Horn
• D. Brake pipe gauge

Answer: (A)

The device used is the Electronic Alertness Control Device, also known as the alerter. It prompts the engineer to acknowledge at set intervals to prove they’re attentive. If there’s no response within the specified time, it can trigger a penalty brake to enforce alertness and safety. This is different from the other devices: a speedometer just shows speed, a horn is for signaling, and a brake pipe gauge indicates brake pipe pressure and doesn’t monitor the operator’s alertness or initiate a penalty brake.
