Before issuing a Form D line 2, what must the Dispatcher ensure about the track?

Before issuing a Form D line 2, the Dispatcher must ensure that the track is clear to the next interlocking. This is critical because a Form D is used to authorize the movement of a train into a specific section of track, and ensuring that the track is clear minimizes the risk of collisions or accidents. The clearance to the next interlocking indicates that there are no obstructions, allowing for safe passage without encountering any other trains, maintenance work, or signal issues in that segment.

While having a clear signal is important for train operations, it does not replace the necessity of ensuring the track is clear. The inspection time is relevant for safety but is not a primary condition for issuing a Form D. Free of maintenance work is also important, but the key requirement is the assurance of clear track to maintain safety and efficiency in train dispatching.
