What action should a train operator take when observing the sign for a ten-car train?

When a train operator observes the sign for a ten-car train, the appropriate action is to resume normal operation. This sign indicates that the train is positioned correctly within the established parameters for operation on that segment of track. The operator can assume that all necessary safety checks and precautions have been accounted for based on the training and protocols in place for handling trains of that length.

The system is designed to ensure that train operators can resume normal operations safely once conditions, such as the length and configuration of their train, are confirmed to be within standard operating limits. By doing so, the operator facilitates efficient movement along the rail network, maintaining schedules and minimizing delays.

Other actions, such as stopping for authorization, reducing speed to 5 MPH, or changing tracks immediately, are typically reserved for specific situations that do not apply when simply observing the sign for a ten-car train. The presence of the sign suggests that the train is suitable to continue at its standard operational speed, permitting the operator to keep the train moving effectively.
