When are track flags authorized to be displayed during track bulletin changes?

Track flags are crucial for ensuring the safety and efficiency of rail operations, particularly during times when track conditions are changing or when maintenance is being performed. The display of track flags following confirmation that a track bulletin has been issued is essential because it signifies that all relevant personnel, including train crews, have been made aware of the updated track status and any associated restrictions or speed limits.

By waiting for confirmation that the bulletin has been issued before displaying the track flags, the dispatcher ensures that everyone involved in the operation is on the same page regarding current track conditions. This minimizes the likelihood of accidents or miscommunication, which could arise from displaying flags prematurely. It reinforces the principle that safety protocols must be communicated clearly and thoroughly before any visual signals are presented on the tracks.

This process also helps maintain the integrity of train operations, as train crews rely on accurate and timely information when making decisions that affect their travel and operational efficiency.
