What action should be taken regarding signal malfunctions?

When faced with signal malfunctions in tower operations, it is crucial to ensure safety and maintain operational integrity. Notifying the RCC (Rail Control Center) about the issue is the appropriate action because the RCC is equipped to handle such situations effectively. They can assess the problem, coordinate a response, and provide necessary instructions to ensure that operations do not compromise safety.

Ignoring the signals or continuing operations could lead to dangerous situations, such as collisions or derailments. Changing the signal manually without proper authorization could also create confusion and safety hazards. Moreover, waiting for other operators to assess the situation could delay critical responses and may lead to miscommunication or extended risks. Therefore, promptly notifying the RCC ensures that the situation can be managed with the necessary oversight and authority.
