Who has authority to issue a stop within Form B limits?

• A. The Conductor
• B. The EIC
• C. The Dispatcher
• D. The Yardmaster

Answer: (B)

Form B limits designate a protected work area overseen by one person—the Engineer in Charge. That person has the authority to issue a stop to any train or movement within those limits whenever protection is needed or unsafe conditions exist. The goal is to ensure the crew can work safely without trains entering the protected site. The Conductor is responsible for operating the train but does not carry the protective authority inside Form B. The Dispatcher manages movements across the broader network, not the specific protection at a Form B site. The Yardmaster handles yard operations, not the protection of a Form B work site. So the person in charge—the Engineer in Charge—has the authority to issue a stop within Form B limits.
