During emergency EOT procedure, after placing the automatic brake handle to the emergency position, what should you do immediately?

• A. Lift the red cover of the EMERGENCY SWITCH and activate the emergency valve on the EOT. Repeat until the HEU indicates pressure at the EOT has vented to zero
• B. Release the brake and wait for the train to stop
• C. Open the EOT bleed valve manually
• D. Ignore and continue applying service brakes

Answer: (A)

When an emergency brake is applied, you must ensure the entire train is secured by venting the brake pipe at the end of the train. Lifting the red cover and activating the emergency valve on the End of Train (EOT) directly accomplishes this by venting the brake pipe pressure at the far end. You then verify with the HEU that the pressure at the EOT has been vented to zero, confirming the emergency brake is fully established along the train. If the HEU doesn’t read zero, you repeat the venting until it does. Releasing the brake and waiting would not remove the residual brake pipe pressure, so the train might not stop or could have incomplete braking. Manually opening the EOT bleed valve isn’t part of the standard immediate action and could bypass the proper sequence. Ignoring the emergency and continuing with service brakes would not satisfy the emergency procedure and could leave the train unreliant on the correct, full emergency braking.
