What does a clear signal look like and what does it indicate?

A clear signal typically consists of a green light or a combination of lights that indicate to train operators that they can proceed. This signal signifies that the track ahead is clear of any obstructions and that the train can continue at normal speed without the need for immediate caution or stopping.

In rail operations, clear signals are critical for maintaining safety and efficiency on the tracks. When a conductor or engineer receives a clear signal, they can confidently move forward, ensuring that they are adhering to the established procedures for maintaining safe train operations.

Other options represent different signals that communicate various instructions or warnings to train operators. For instance, a stop signal would indicate that the train must halt immediately. A signal indicating to proceed prepared to stop would require the operator to maintain a level of caution, while a warning signal that instructs to slow down suggests an upcoming change or potential hazard on the track. Understanding the meaning of clear signals is essential for effective train operation and safety.
