Track Vehicles must enter or be placed on Running Lines only:
within the limits of an Occupancy Authority; or
at approved on and off Track Locations where the approach of Rail Traffic can be
managed by Controlled Absolute Signals.

must be verified using one or more of the following:
a kilometre sign and Section;
