How do you pass a Block Limit signal to do station work?

When passing a Block Limit signal to perform station work, the appropriate method is to proceed at restricted speed with an A-Card. This approach ensures safe operations while executing tasks in proximity to the track, as restricted speed allows for control over the train's movement, enabling the crew to stop within half the distance of visibility ahead. The A-Card serves as an authorization for the crew to pass the signal under specific conditions, indicating that it is understood the train cannot exceed the restricted speed limit while moving past that signal.

This procedure prioritizes safety, particularly in situations where work is being done near or on the tracks, minimizing the risk of collisions or accidents. Overall, utilizing restricted speed with an A-Card is critical in maintaining safety standards and ensuring compliance with operating rules while performing station work.
