What happens to a previous timetable when a new one takes effect?

When a new timetable takes effect, the previous timetable is automatically revoked. This process ensures that there is no confusion or overlap in scheduling and that all train movements are based on the most current information available. This revocation is crucial for maintaining safety and efficiency in rail operations, as it allows dispatchers, engineers, and other personnel to rely on the latest timetable for their planning and decision-making.

The other options, such as archiving the previous timetable or allowing it to remain active for a specified duration, do not align with operational protocols that prioritize updated information. Instead, the automatic revocation of outdated timetables streamlines operations and minimizes the risk of errors that could arise from using old data.
