How is notification of a new timetable communicated?

The correct answer is communicated by general order and track bulletin because these methods are specifically designed for conveying important operational updates and changes in the railway system. General orders provide comprehensive information to all relevant personnel about any changes, including timetables, safety protocols, and operational procedures. Track bulletins serve as an essential means of communication that informs crew members about current and future track conditions, allowing them to operate trains safely and efficiently according to the updated timetable.

Using a general order and track bulletin ensures that the information is distributed officially and reaches all employees involved in train dispatching and operations. This systematic approach maintains safety standards and operational integrity, making these channels ideal for such critical updates.
