When a train operator sees a yellow lantern waved up and down, what should they expect?

When a train operator sees a yellow lantern waved up and down, it is a signal indicating that there is another group of workers located a short distance beyond the signal point. This type of signal is used to alert the train operator to be cautious and aware of potential workers on or near the tracks, allowing them to prepare for any necessary actions to ensure safety.

Recognizing this signal helps the operator to maintain awareness of the work being done on or near the railway, thus reducing the risk of accidents. It’s essential for the operator to understand the implications of the signal so they can execute the appropriate response while operating the train in a safe manner. The context of the situation typically encourages vigilance and safety rather than an immediate stop or drastic reduction in speed unless specifically indicated by other signals or conditions.
