What type of braking is engaged with a loss of stationing numbers?

In the context of train operations, when a loss of stationing numbers occurs, emergency braking is typically engaged to ensure the safety of the train and its passengers. Stationing numbers are essential for the train's control systems to determine its exact position and speed. If these numbers are lost, it indicates a significant issue that could affect the control of the train, leading to a potential safety hazard.

Engaging emergency braking in such a situation serves as a precautionary measure to bring the train to a halt as quickly as possible under uncertain conditions. This type of braking system is designed to activate rapidly and provides maximum stopping force, helping to prevent accidents or collisions that could arise due to the loss of critical operational data.

Normal, dynamic, and electromagnetic braking methods are generally employed under regular operational conditions, where the train's position is known and monitored effectively. However, they might not provide the immediate response required in a situation where there is a loss of control data. Thus, utilizing emergency braking is the most appropriate response to safeguard the train's operation during such emergencies.
