What action is required for a train to change its direction of movement?

Having permission from the Train Dispatcher is essential for a train to change its direction of movement. The Train Dispatcher is responsible for overseeing train movements on the railway network, ensuring safety and proper coordination between different trains. When a train needs to reverse or switch tracks, it is necessary for the engineer to receive explicit instructions or authorization from the Dispatcher to prevent any potential conflicts with other train movements.

This requirement emphasizes the importance of communication and authority in rail operations, ensuring that all movements are planned and executed safely. By getting permission, the train is compliant with operational protocols that help to maintain a safe and efficient transit system. The other actions, while important for overall train operation and safety, do not specifically address the need for authorization to change direction. Proper permissions are critical in preventing accidents and ensuring the smooth operation of train services.
