What is the purpose of Marker Signals in train operations?

Marker signals are crucial in train operations primarily for controlling train speed. These signals provide visual cues to train operators regarding the speed limits that must be adhered to in various sections of the track. By indicating appropriate speed limits, they ensure the safe and efficient movement of trains, helping to prevent collisions or derailments.

While control over train speed is the principal function, it’s important to understand that marker signals can also indirectly imply other operational aspects, such as caution when approaching potential hazards or changes in track conditions. However, their main role focuses on speed regulation, which is vital for maintaining safety standards in busy railway environments.

Understanding the nuances of how these signals operate can greatly enhance a train operator's ability to respond appropriately to changing conditions on the track. It is essential for operators to be well-versed in interpreting these signals to uphold the safety and efficiency of train operations.
