What is a Bulletin Order (BO)?

A Bulletin Order (BO) is specifically focused on notifying employees of changes that affect train movements. This includes crucial information about track conditions, speed restrictions, changes in schedules, or any other updates that may impact the safe operation of trains. Such notifications are vital in ensuring that all personnel are informed and can make necessary adjustments to their operations to maintain safety and efficiency on the railroad.

The other options do not accurately capture the essence of a Bulletin Order. For instance, while some forms of publications may summarize train schedules, that function is not the primary purpose of a Bulletin Order. Likewise, details about passenger information and crew assignments are typically found in different publications tailored to those specific needs, separate from the operational focus of a Bulletin Order. Therefore, the emphasis on notifying employees of changes that directly impact train movements is what distinguishes a Bulletin Order and underscores its importance in operational communications.
