What does a green MAL bar signify to the train engineer?

A green MAL (Movement Authority Limit) bar indicates that the track ahead is clear and safe for the train to proceed. This signal is crucial for train engineers, as it assures them that they can move forward without any immediate concerns or restrictions. It assures the engineer that the area ahead has been inspected and deemed safe for travel, allowing the train to maintain a regular speed and operation.

In the context of train operations, understanding visual signals is essential for safety and efficiency. Therefore, recognizing that a green MAL bar represents safety and authorization to continue traveling is fundamental for the operation of the train. It effectively communicates the status of the track ahead and enables the engineer to make informed decisions during their journey.
