What should you do when ready to depart after performing a train check?

When preparing to depart after conducting a train check, moving the automatic brake handle to RELEASE is the appropriate action. This step is crucial as it enables the train to be ready for departure by releasing the brakes, allowing for safe and efficient movement.

Doing this ensures that the train's braking system is disengaged, allowing it to respond properly when power is applied. This action is essential for effective train handling, minimizing the risk of unwanted delays or safety issues when starting the train.

While notifying the conductor, securing loose items in the cab, and initiating a final air test are important tasks that need to be considered in the overall procedure of train operation, the immediate step to allow for departure after a thorough check focuses primarily on releasing the brakes. Thus, moving the automatic brake handle to RELEASE is a foundational action that directly facilitates the train's movement.
