What does a green MAL bar represent?

A green MAL bar indicates that the track is clear for up to 3,500 feet. This signal is vital for train operations, as it provides engineers with information about the state of the track ahead. When the MAL bar displays green, it assures the engineer that there are no obstructions or hazards within that specified distance, allowing for safe and efficient travel at higher speeds.

The significance of the specified distance is crucial for train operation, as different colors or readings on the MAL bar convey various lengths of clear track, influencing speed and operational decisions. Understanding the implications of each signal and its corresponding distance contributes significantly to ensuring safety and maintaining schedules in train operations.
