What must a dispatcher issue to authorize another train to follow a non-shunting train into a block?

• A. A Form D line 12
• B. A Form D line 13
• C. A Form C notice
• D. A verbal authorization

Answer: (B)

To authorize another train to follow a non-shunting train into a block, a dispatcher must issue a Form D line 13. This procedure is essential for maintaining safety and coordination on the railway network. Form D line 13 specifically indicates that another train is permitted to enter a block that is occupied by a non-shunting train, ensuring that all trains involved are aware of the movement and that proper precautions are in place. It serves as a formal communication tool between the dispatcher and the train crews, providing clear instructions regarding the movement and occupancy of tracks. This minimizes the risk of accidents or collisions, thereby enhancing operational safety. Using a different form, such as Form D line 12 or a Form C notice, would not correctly convey the specific permission and context required for this situation. Verbal authorization might not provide the necessary documentation and clarity needed in a railroad setting, where recorded communication is vital for safety and operational integrity. Therefore, issuing a Form D line 13 is the correct and necessary action in this scenario.
