What authority is required to pass a stop signal at Nassau?

Passing a stop signal at Nassau requires Verbal Rule 241 authority. This rule is specifically designated for situations where a train may need to pass a stop signal under controlled conditions, typically necessitating direct communication between the train crew and the dispatcher or a designated authority.

Verbal Rule 241 is implemented to ensure safety while allowing trains to proceed past signals that would otherwise prohibit movement, as long as the necessary precautions are taken, such as ensuring the track ahead is clear and no conflicts with other trains occur. This ensures that all personnel involved are aware of the situation and can coordinate effectively to maintain safe operations.

Other options such as written notice, automatic clearance, and Form D authorization do not apply in this context. Written notice typically refers to more formal notifications and procedures which are not suitable for the urgency of passing a stop signal. Automatic clearance allows for passage without specific authorization but is not typically applicable to a stop signal situation. Form D authorization is a different type of authority used for specific instructions or operating conditions, but it does not replace the need for the specialized permission granted by Verbal Rule 241 in this scenario.
