If a train has an operative EOT and is uncoupled and recoupled within 24 hours, what must be verified before proceeding?

• A. The EOT battery voltage is charged.
• B. The coupler alignment is within spec.
• C. The brake shoe wear is within limits.
• D. The brake pipe pressure is restored at the rear end of the train.

Answer: (D)

Reestablishing brake pipe pressure at the rear end after reconnecting is essential to ensure the braking system can be controlled correctly along the whole train. When the train is uncoupled, the brake pipe circuit can be interrupted, and upon rejoining, you must confirm that the brake pipe pressure has been restored at the rear so brakes will release and apply as needed, and the End of Train device can monitor and communicate properly. This verification ensures the train maintains safe braking capability and that the rear-end signaling provided by the EOT is valid again before proceeding. While having a charged EOT battery is important for the device to operate, and checking coupler alignment or brake shoe wear can be relevant in other contexts, the immediate safety check required here is that brake pipe pressure is restored at the rear end of the train.
