What action will the Train Movement Office take upon receipt of a speed restriction?

Upon receiving a speed restriction, the Train Movement Office typically informs the originating office about the first train receiving the Form D. This action is crucial as it ensures that all relevant parties are aware of the new speed limitation and can take the appropriate steps to communicate that information to train crews.

Communicating with the originating office is important for maintaining safety and compliance with speed restrictions, as it allows for coordinated action in managing train movements effectively. This helps in ensuring that crews are alerted to any changes in the operating conditions, thereby enhancing safety and minimizing the risk of accidents due to excessive speeds.

The other options may not align with the standard operating procedures regarding how speed restrictions are communicated and managed within the rail network. By focusing on informing the originating office, the Train Movement Office ensures that the information is correctly distributed to the necessary personnel, allowing for timely and efficient operational adjustments.
