What does it indicate when a train stops immediately after running over RTS?

When a train stops immediately after running over a Runaway Train Signal (RTS), it signifies a critical event that necessitates further examination of the train's condition and operational status. This procedure is essential because running over an RTS typically indicates that there may have been a significant issue detected that could affect the safety of the train and its operations. Stopping allows for a thorough inspection to ensure that the train is safe to continue its journey.

The need for inspection arises from the nature of the RTS, which is an indication to train crews that there may be a risk related to the train's performance or the conditions ahead. By inspecting the train immediately after such an event, crews can identify and address any potential mechanical failures, safety hazards, or any other irregularities that may have caused the train to encounter the RTS. Therefore, the protocol for stopping and inspecting is a vital safety measure.

Other options refer to responses that do not encapsulate the necessary course of action following the event of running over an RTS. A caution signal signifies a warning but does not specifically necessitate an immediate inspection of the train itself. Similarly, if an emergency situation were declared, it would suggest a more severe condition is present that might require further actions beyond just inspection. The idea that
