May a control operator give verbal authority to pass a stop signal when a proceed indication could be displayed?

A control operator may give verbal authority to pass a stop signal only when specific conditions are met, primarily concerning safety and protocol. In this case, such authority is restricted and is permissible only if it is for protection within Centralized Traffic Control (CTC) limits. When there is a potential for a proceed indication to be displayed, the automatic systems in place are designed to maintain safety by not permitting trains to pass a stop signal without assurance that the track ahead is clear and safe. This is essential to prevent accidents and ensure that trains can operate safely under the control of the dispatcher.

Providing a verbal authority to pass a stop signal without adhering to these guidelines could lead to unsafe situations, especially when a proceed indication could be shown. The CTC limits are established to ensure that all operations under verbal authority are done under controlled and safe circumstances, which comprehensively contributes to the safety protocols of train operations.
