An ATP Possession is authorised by ARTC Network Control on the day of operation, between mandatory
and ad hoc services only, and allows all trains to transit as required. Work teams must clear the track
ahead of all train movements.
Operating restrictions or alternate systems of safe working, excluding TSRs, should not be implemented
at the conclusion of an ATP Possession. If it can be reasonably forseen that operating restrictions or
alternate systems of safe working will be required following fulfilment of the Possession, an ATP
Possession is not appropriate.
Reoccurring and/or advance notice ATP Possessions shall be advertised in the Interstate Possessions
Calendar where practical to do so. ATP Possessions that have been published in the Possessions
Calendar will be subject to an initial review and included in works coordination activities where required.
If scheduling conflicts occur, advertised ATP works will be given priority of over non-advertised works.
