Under blue flag conditions, when may you release the hand brakes on your train?

• A. Immediately after the flag is placed.
• B. Never; hand brakes must remain released.
• C. When the locomotive is started.
• D. Only if directed by the employee who placed the blue flag or the EIC.

Answer: (D)

Blue flag protection means the track is safeguarded and no train movement should occur until someone in charge authorizes it. The person who placed the blue flag, or the engineer/employee in charge, has the authority to direct when it is safe to release the hand brakes and proceed. Releasing hand brakes without that explicit direction could move equipment into a protected area and endanger workers, so movement—or release of brakes—is only allowed when specifically instructed by the flagger or the EIC. This is why you must await their directive before releasing the hand brakes. The other scenarios would bypass the required authorization.
