When does the Out of Service indication disappear?

The Out of Service indication is designed to ensure the safety and operational integrity of train services. This indication disappears when the train arrives at the station where it will be removed from service. This is critical because it marks the transition point where the train is officially no longer in operation for passenger transport and can undergo any necessary inspections, repairs, or servicing without posing risks to passengers.

The other options may seem plausible, but they do not accurately reflect the operational protocols associated with the Out of Service indication. For instance, simply leaving a station or reaching a certain speed does not signify that the train is ready to resume service; it merely indicates movement through the network. Additionally, initiating a pick-up does not ensure that the train’s operational status has changed—it may still be considered out of service until it reaches its designated station for removal. Understanding these processes is essential for maintaining safety standards and compliance in train operations.
