What action should be taken when a light locomotive consist is operated over a distance exceeding 2 miles without crew control via signals?

When a light locomotive consist is operated over a distance exceeding 2 miles without crew control via signals, the appropriate action is to operate from the cab nearest the direction of travel. This is crucial for ensuring effective control of the locomotive, as it allows the crew to maintain optimal situational awareness and response capabilities. Being positioned in the cab that is facing the direction of travel enables the crew to better observe track conditions, signals, and any potential hazards ahead.

In scenarios where signal control is not available, relying on the capabilities of the crew in the cab nearest the direction of travel enhances safety and operational efficiency. It ensures that the crew can react promptly to any changes in the environment, and maintain better oversight of the train's movements.

While automated controls may provide convenience, they do not replace the valuable assessment and decision-making skills of trained personnel present in the cab. Stopping the locomotive until communication can be established might lead to unnecessary delays or hazardous situations if the environment on the track changes. Switching to manual control might imply that there is a lack of confidence in the automated system, but operating from the more advantageous cab setup provides a consistent framework for safe operations under the given circumstances.
