A train approaching a fixed signal requiring a stop must stop before any part of the movement passes the signal. If a train passes a Stop signal without permission, which actions are required?

A train approaching a fixed signal requiring a stop must stop before any part of the movement passes the signal. If a train passes a Stop signal without permission, which actions are required?

• A. Notify the train dispatcher
• B. Provide warning against approaching trains
• C. Both notify the dispatcher and warn approaching trains
• D. Neither action is required

Answer: (C)

When a train passes a Stop signal, it creates a hazards in the track layout that other trains may be relying on for safe movement. The immediate response is to coordinate with operations and alert others. Notifying the dispatcher ensures the movement is documented and proper protections can be put in place—such as updating track authority, blocking the line, or issuing further instructions to prevent additional accidents. At the same time, warning approaching trains helps prevent secondary collisions by giving crews advance notice that a train has violated a signal and may be stopped or held ahead. Taking both steps is necessary because each action addresses a different aspect of safety: communication with the dispatcher handles the official protection and sequencing of movements, while warnings to other trains mitigate the immediate risk of following trains entering a compromised or occupied block. If you only do one, you could miss either the procedural protection or the oncoming-train safety, leaving a gap in the emergency response.
