After the initial stop on a controlled track, what additional information must be broadcast every 15 minutes?

• A. The above information (that the train has stopped).
• B. The current speed of the train.
• C. The train's destination.
• D. The time of day only.

Answer: (A)

On a controlled track, once you’ve stopped, you must keep the dispatcher informed about your status. Broadcasting that you have stopped every 15 minutes provides a current status update that confirms the block is still occupied and that no movement is occurring. This ongoing report prevents misunderstandings about whether the train is still in the block or has progressed, and it helps the dispatcher manage authority and track occupancy safely. Current speed isn’t relevant while the train is stopped, since there is no speed to report. Destination is useful information in other contexts, but it doesn’t convey the active status of the track or occupancy. Time of day alone also doesn’t communicate your location or status within the controlled network. Therefore, the essential broadcast is that the train has stopped.
