To reverse direction within the limits of an interlocking, trains must have either?

• A. Proper interlocking signal
• B. Permission from the Dispatcher
• C. Form D authorization
• D. Verbal approval from the Engineer

Answer: (B)

Reversing direction inside an interlocking requires explicit movement authority to prevent conflicts with other trains or routes. The dispatcher holds that authority and can issue clearance after confirming track occupancy and the status of all routes within the interlocking. Even if a signal is in a legible aspect, it doesn’t alone authorize a reverse move; formal dispatcher permission ensures coordinated, safe changes of direction. Verbal approval from the engineer isn’t sufficient because the control of movement within interlockings rests with dispatcher-issued authority, and Form D may apply in specific procedures but isn’t the standard authority for this reversal.
