What does a RED OVER RED signal instruct an operator to do?

A RED OVER RED signal indicates that the operator must stop and stay in place. This signal means that the track is not clear ahead, and the operator must adhere to this directive for safety reasons. It is important for the operator to ensure that no movement occurs until receiving further instructions or until the signal changes to a more permissive aspect. The location of the signal and the need for caution underscore the importance of maintaining a safe environment for both train operation and the safety of personnel and equipment on or near the tracks.

In this context, stopping is essential to prevent potential collisions or derailments, making the interpretation of this signal critical for safe rail operations.
