The ECO prepares a Blocking of Track Sections for Electric Traction Purposes (BF)
form for De-Energisation of Overhead Supply, and issues the BF to the Train
Controller.
If De-Energisation of Overhead Supply affects more than one Train Controller, the
Train Controllers for the affected areas must confer and give clearance to De-Energise
the Overhead Supply on the BF.
The ECO must obtain Authority from the affected Train Controllers before DeEnergisation of the Overhead Supply.
