What should a train operator do after passing a certain sign that indicates no signal indications?

A train operator should operate without signal indications after passing a sign that indicates no signal indications. This means the operator must proceed with caution, as standard signals are not in effect, and the usual guidance for speed and operational procedures is not provided.

In this scenario, the absence of signals implies that the operator must rely on their training, experience, and situational awareness to navigate the track safely. Operating without signal indications necessitates a heightened level of attention, as the operator is responsible for ensuring the train is operated safely and in accordance with any applicable operating rules and regulations.

Understanding that signal indications are absent allows the operator to anticipate potential hazards or changes in track conditions and act accordingly. This approach prioritizes safety, enabling the train operator to make informed decisions based on the unique circumstances of the journey.
