Under what condition may you move cars with handbrakes applied?

• A. Always
• B. Except when testing the effectiveness of the handbrake
• C. Only during maintenance
• D. Never

Answer: (B)

Handbrakes are there to hold railcars in place, not to enable movement. Moving cars with the handbrake applied is normally unsafe and causes excessive wear on the braking system, potential wheel damage, and a risk of uncontrolled movement if the brakes fail to hold.

The only time you would purposefully move cars while the handbrake is applied is as part of a handbrake effectiveness test. In that scenario, you apply the handbrake and then attempt a controlled movement to verify whether the brake holds. If the car does not move, the brake is working correctly; if it moves, the braking needs inspection or adjustment. After completing the test, the handbrake is released for normal operations.
