3. AUTHORISATION

Before Authorising the LPA, the Train Controller must make sure that:
 another Work on Track Authority is not in use within the proposed limits;
 approaching Rail Traffic can be Restrained at both ends of the Section that includes
the proposed limits;
 Rail Traffic that is Stabled and not associated with the LPA, but still being within the
limits of the LPA, must not be Authorised to move;
 Rail Traffic associated with the LPA, within the limits has been identified and is
being managed as agreed by the PPO and the Train Controller;
 the PPO knows about any existing obstructions;
 Blocking Facilities have been applied to prevent the Unauthorised entry of Rail
Traffic into the proposed limits; and
 in single line territory, the Half Pilot Keys have been removed from both ends of the
affected Section.
The Train Controller must confirm with the PPO the following:
 name and contact details of the PPO;
 type of work;
 intended start and finish times; and
 location, using one or more of the following identifiers:
o a kilometre sign and Section;
o station name;
o Overhead Line Equipment (OLE) structure number;
o a Points number;
o a Signal number;
o an observance of Points or Signal Aspect change;
o permanent structures, such as a bridge, roadway or overpass, used only in
conjunction with one of the above identifiers; or
o another identifier.
Where an existing Work On Track is in place, the Train Controller may Issue the LPA
only if the existing Work On Track is Fulfilled or ended.
