Which visual indication confirms the hand brake is applied?

• A. The brake shoe is pressed against the wheel
• B. The hand brake chain is loose
• C. The gauge shows full pressure
• D. The train is stationary

Answer: (A)

The confirmation that the hand brake is applied is indicated by the brake shoe being pressed against the wheel. When the hand brake is engaged, it exerts pressure that pushes the brake shoes into contact with the wheel. This physical contact generates friction, which holds the train in place and prevents movement. Observing the brake shoe against the wheel is a direct and clear visual indication that the hand brake is functioning as intended. In contrast, other options do not provide reliable confirmation of the hand brake's application. For example, a loose hand brake chain could potentially indicate that the brake is not fully engaged. A gauge showing full pressure typically relates to the air brake system rather than the hand brake, providing no information about the hand brake status. Finally, while the train being stationary could suggest the brakes are applied, it does not specifically confirm that the hand brake itself is engaged, as the train might be stationary due to other brake systems or factors.
