How can a train pass a fixed signal displaying stop?

Passing a fixed signal displaying stop typically requires specific authorization, which is crucial for maintaining safety protocols within train operations. A Verbal Part-241 or Train order provides the necessary instruction from the dispatcher or authority, allowing the train to proceed past the stop signal under controlled and communicated conditions. This authorization ensures that the train crew is fully aware of the situation and has received formal permission to bypass the restriction indicated by the signal.

The intent behind this rule is to prevent accidents and ensure that the train operates safely within the prescribed guidelines. The proper communication channels, such as a Verbal Part-241 or Train order, are established to maintain clarity about which trains are permitted to pass a stop signal, thereby safeguarding both the train crew and the overall railway system.

Options that suggest automatic authorization, physical signals from the conductor, or proceeding based solely on the last known signal do not ensure the level of communication and oversight required for safety when dealing with stop signals. These alternatives lack the formal mechanism of authorization that is critical in such circumstances, where adherence to protocol is paramount.
