What does an illuminated S signal indicate for a train?

• A. A warning to slow down
• B. Proceed at regular speed
• C. Stop immediately
• D. Prepare to stop at the next signal

Answer: (A)

An illuminated S signal specifically indicates a warning to slow down. This signal serves to alert train operators that they should reduce their speed in anticipation of changing conditions ahead, such as a lower speed limit, the presence of track work, or a potential stop signal. The purpose of this warning is to ensure the safety of the train and its passengers by allowing sufficient time to react to any upcoming changes in operation or track conditions. While other signals indicate different actions, the S signal is uniquely designed to communicate the need to decelerate. Understanding this warning is essential for maintaining safe train operations and preventing accidents or delays.
