How far ahead does the green MAL bar represent a clear track?

The green MAL (Movement Authority Limit) bar indicates that there is a clear track that extends up to 3,500 feet ahead of the train. This visual signal is critical for train engineers as it provides them with information about the route ahead, allowing them to proceed safely at the appropriate speed. Understanding the distance represented by the green MAL bar helps engineers make informed decisions regarding acceleration, braking, and overall operational safety. The precise distance of 3,500 feet is standardized in train operations, reflecting industry practices and regulations designed to ensure safe train movements while also maintaining efficiency within rail operations.
