Suppression Position is used for what?

Suppression Position is used for what?

• A. To reset the brake system following a Penalty Brake Application.
• B. To vent brake pipe to approximately 10 psi.
• C. To apply emergency brakes.
• D. To store the system.

Answer: (A)

Suppression is the control step used to clear a Penalty Brake Application and return the brake system to normal service. When a penalty event occurs, the brakes have been applied automatically and the train is held in that penalized state. Moving the control to suppression releases that penalty, resets the braking system, and allows normal braking operations to resume. It isn’t about venting the brake pipe, applying emergency brakes, or storing the system—its purpose is specifically to reset after a penalty event.
