Before the conductor opens the angle cock on the head end of a train, which steps should be completed?

• A. Notify the Conductor to Open the Angle Cock
• B. Release the Automatic Air
• C. All of the Above
• D. Press Normal and Execute on the Remote Screen

Answer: (C)

Before opening the angle cock on the head end, you want to make sure communication, readiness, and deliberate control are all in place. Notifying the conductor guarantees that the crew is aware of the action and authorized to proceed, preventing miscommunication or unexpected operations. Releasing the automatic air ensures the brake system is in the proper state to allow a controlled flow of air when the valve is opened, avoiding sudden or unintended brake changes. Using the remote screen to press Normal and Execute confirms you’re operating in the correct control mode and that this action is intentional, reducing the risk of accidental activation. All of these steps together address different safety aspects: coordination, system readiness, and deliberate control. Skipping any one of them could lead to miscommunication, an uncontrolled air release, or an inadvertent operation, so performing all of them is the safest and best practice.
