Movements operating in the out-of-service portion of the track must not enter the in-service portion without?

• A. Stop-Release permit
• B. Permission of the dispatcher
• C. Permission of the Engineer in Charge
• D. A Bulletin Order

Answer: (B)

When crossing from an out-of-service portion into an in-service track, you must have the dispatcher's permission. The dispatcher controls track occupancy and can issue the proper authority to enter, ensuring the way is clear, switches are set, signals are correct, and any required protection for the area is in place. Without that clearance, entering the in-service portion could conflict with other movements or conditions on the track. The other options don’t provide the necessary authority to re-enter service: a Stop-Release permit is used for specific work-zone procedures, not general reentry into service; the Engineer in Charge oversees the work crew rather than train movements’ entry; and a Bulletin Order is an incidental instruction, not the standard authorization to move into service.
