Before De-Energisation of the Overhead Supply, the ECO must inform the Train
Controller of the affected Electrical Section. The Train Controller must check the
Electrical Section on the Train Control system.
The ECO and the Train Controller must confer and make sure that details about the
Authority to De-Energise the Overhead Supply correspond with the Overhead
Sectioning Diagram.
The Train Controller must make sure that, in the Electrical Section to be De-Energised:
there is no Rail Traffic requiring electric traction that might need to be moved during
the period of De-Energisation; and
the Pantographs of Rail Traffic have been lowered.
