In what step do you select "TRAIN CHECK" during the train check process?

Selecting "TRAIN CHECK" during the train check process occurs at the third step. This step is crucial because it involves confirming that the train's air brake system and functionality meet safety standards before departing. By selecting "TRAIN CHECK," you initiate the specific procedures to assess various aspects of the train's operation, including brake effectiveness, leak checks, and overall readiness for safe movement.

This step is pivotal as it ensures that any issues with the train's air brake system are identified and addressed before the journey begins. Conducting a proper train check helps maintain safety and operational integrity, which are essential for both crew safety and the safe transport of cargo or passengers.

Understanding the sequence involved in the train check process, with "TRAIN CHECK" as a significant action at the third step, is vital for effective train handling and compliance with safety protocols.
