What does a green lantern suspended on the right-hand side of the track indicate?

A green lantern suspended on the right-hand side of the track indicates that train operators can resume normal operations in accordance with any fixed signals. This signal is significant as it conveys a sense of safety and assurance, allowing the train crew to continue their journey without restrictions, provided that all other operational guidelines and signals allow for it.

The configuration of a green lantern is universally recognized in train operations, aligning with the color's meaning in signaling—indicating that it is safe to proceed. Understanding this signal is critical for maintaining flow and safety in train operations, ensuring that the crew is aware of their ability to move forward without hindrance or need for caution. This knowledge is essential for train operators to make informed decisions based on the signals they encounter while on duty, thereby ensuring efficiency and safety in rail operations.
