What happens when a train stops with an emergency brake application?

When a train stops due to an emergency brake application, the stationing marker number indication disappears from the Train Operating Display (TOD). This is a critical safety feature that indicates to the crew that the train is no longer in motion and has come to a complete stop. The disappearance of the stationing marker number serves as a visual cue to the engineers that they need to assess the situation, understand the reason behind the emergency stop, and take the necessary actions to ensure passenger safety and train integrity.

The other possibilities do not accurately reflect the behavior of the train during an emergency stop. For instance, continuing at a reduced speed would not occur as the purpose of an emergency brake is to bring the train to a full stop immediately. The activation of emergency lights may vary based on operational protocols, but it's not a direct result of an emergency brake application. Lastly, the need for a manual restart is a possibility, but it does not universally apply or occur immediately following an emergency stop, as operational procedures may dictate the next steps differently based on the circumstances of the stop.
