What action is required when an unidentified track occupancy (UTO) indication appears?

When an unidentified track occupancy (UTO) indication appears, the appropriate action is to notify the train crew and route movements around the UTO. This is important because a UTO could indicate the presence of a train or an obstacle on the tracks that is not being monitored, which poses a significant safety risk. By alerting the train crew, they can be made aware of potential dangers and ensure that trains are rerouted to avoid any accidents or collisions.

Handling a UTO with caution is crucial to maintaining safety on the rail network. This ensures that all personnel are informed and can take necessary precautions, while also allowing train operations to continue without putting lives or equipment at risk. Properly routing around the UTO also helps in investigating the issue effectively and resolving it more quickly.
