What is the initial step in recovering from an emergency brake application?

The initial step in recovering from an emergency brake application is to move the speed selector to stop. This action is critical as it ensures that the train is brought to a complete halt, preventing any further movement that could lead to unsafe conditions. By stopping the train immediately, the operator can assess the situation effectively without the risk of the train continuing to travel, which could complicate the recovery process and pose additional hazards.

Once the train is stopped, the operator can then proceed with necessary checks, such as verifying the status of the RCT battery or communicating with other operators. However, the priority in an emergency situation is to secure the train first before any further actions are taken. Keeping the train under control is essential for the safety of both the operators and any personnel in the vicinity.
