What is indicated by the presence of a solid green signal?

A solid green signal indicates that the track is clear for movement. This means that a train can proceed without restrictions, as there are no obstacles or hazards ahead. The signal conveys safety and provides the crew with assurance that the route is safe for travel at normal operating speeds.

In operating rules, a solid green is a positive indication intended to simplify communication regarding the train's movement and the condition of the track. Understanding this signal and its implications is essential for railway personnel to maintain safe and efficient operations on the railroad.
