When hand-operated switch(es) have been restored to normal position, even though the train has not been reported clear of the block, it must not again enter that block without?

When hand-operated switch(es) have been restored to normal position, even though the train has not been reported clear of the block, it must not again enter that block without?

• A. The Dispatcher’s instruction
• B. Permission of the Dispatcher
• C. A new train order
• D. An additional signal

Answer: (B)

When a hand-operated switch is restored to normal, the block isn’t automatically protected again just because the switch is back in place. The movement may still be occupying the block or not yet reported clear, so entering the block requires explicit authority. The only safe and correct way to re-enter is to have the Dispatcher's permission, which authorizes that movement to proceed into the block. This keeps the dispatcher aware of track status and prevents conflicts with other trains or movements. A new train order isn’t required for this re-entry, and an extra signal isn’t a guaranteed means of protection in this situation.
