How is an Absolute Block Signal represented?

Solid Green Light
Flashing Red Light
Flashing Yellow Light
Alternating Flashing Lights

The correct answer is: Flashing Red Light

The representation of an Absolute Block Signal is indicated by a solid red light. This type of signal means that the track is closed to train movements, ensuring that no other train can enter that segment of the track until the signal changes. It is a crucial safety measure that ensures the safety of trains and their passengers by preventing collisions on the track. In the context of the other options, a solid green light would indicate that it is safe to proceed, which is not the case for an Absolute Block Signal. Flashing yellow lights typically indicate caution or a warning that the signal will change soon, while alternating flashing lights are commonly used for warning signs or alerts rather than for absolute block conditions. Therefore, a flashing red light would be more appropriate as a representation of a stop or danger signal, clarifying that entry to the block is prohibited.
