What happens to the Form L if a train’s schedule is annulled?

When a train's schedule is annulled, the Form L associated with that schedule becomes void. The Form L, used to outline the conditions of train operations, including schedules, is no longer applicable once the train is no longer following its original timetable. This ensures that there is clarity and accuracy in train operations, as any instructions or permissions granted in the Form L would no longer be relevant or enforceable.

In contrast, other choices suggest that the Form L would be modified, remain effective, or could be reinstated, which would not align with the operational protocol for annulled schedules. A void status clearly indicates that the Form L should not be relied upon for any subsequent operations related to that annulled train schedule.
