What should an operator do if they see a flashing red signal?

When an operator sees a flashing red signal, it generally indicates an immediate need to stop the train. This signal serves as a critical communication from the control system, warning the operator of potential hazards ahead or indicating that the track may be blocked or unsafe for passage.

Stopping and calling the Control Center is the appropriate response to ensure safety and receive further instructions. This action allows for proper assessment of the situation and enables coordination with other trains or operations that may be affected. It helps to prevent accidents and ensures that the train only proceeds when it is safe to do so, aligning with safety protocols and operational procedures.

Moving with caution or at the same speed in such a scenario would not only disregard the warning conveyed by the flashing red signal but could also lead to potentially dangerous situations. Additionally, speeding up to pass the signal would be reckless and undermine the safety of all rail operations. Thus, the first action should always be to stop and seek clarification from the Control Center.
