If a train has an inoperative EOT and is uncoupled and recoupled within 24 hours, what is required before proceeding?

• A. Verify the brakes on rear car apply and release from a 20-psi brake pipe reduction.
• B. Confirm the train's weight is within limit.
• C. Check the lead locomotive air brake test is current.
• D. Verify the locomotives' headlights function.

Answer: (D)

When an End-Of-Train device is inoperative, you lose the automatic rear-end signaling it provides, so visibility and signaling cues from the train’s tail become a safety concern. If the train is uncoupled and recoupled within a short window, the immediate safety action is to confirm that the locomotives’ headlights function. Working headlights ensure the rear of the train remains visible to the crew and to trackside observers, which helps prevent rear-end collisions and miscommunication when the EOT is not available. The other checks aren’t specifically tied to this EOT-inoperative scenario after a quick uncouple/recouple. Brake tests or weight limits, while important in other contexts, don’t address the direct safety need created by an inoperative EOT in this particular situation, and the lead locomotive air brake test, while generally important, isn’t the immediate required action here.
