An End Section Authority/Start CTC board is located adjacent Signal BBK/26.
Section Authorities issued from Tooli Block Point to Berrybank Loop shall continue to indicate a ‘Key Loop/Main Instruction’ on the Authority text, as far as practicable the Network Controller shall signal movements through Berrybank Loop in accordance with the text on the Section Authority as far as practicable.
All rail services will be signalled through Berrybank Loop in accordance with TA20 Section 17 "Centralised Traffic Control System". ALL Train Crews MUST proceed through Berrybank Loop as per the signal indications.
