What authority does the train have while operating under Form D line 2?

When operating under Form D line 2, the train has exclusive occupancy of the track. This means that the train has been given the authority to occupy a specific section of track without the possibility of other trains sharing that same track space at the same time. This is crucial for safety, as it ensures that the train can proceed without the risk of encountering another train on the same track segment.

In this context, exclusive occupancy indicates that the dispatcher has provided the train with a clear and unequivocal authority to operate in that area, typically for purposes like maintenance or when a section is closed to other traffic. This prevents any conflicting movements from other trains and provides a safe operating environment.

Other choices do not reflect the specific authority granted in Form D line 2. Shared occupancy involves multiple trains using the same track simultaneously, which is not allowed under this authority. The authority to make any kind of stops does not align with the exclusivity of occupancy, as it suggests flexibility not typically afforded in this scenario. The authority to reverse at any point would also imply a different operational context, which does not apply to the exclusive nature of Form D line 2 occupancy.
