A

Brought to signal at danger with hand signaller and red flag (this is entrance signal), 2nd hand signaller located at exit signal, 1st hand signaller issues TBW ticket (RT3184), once you have RT3184 and yellow hand signal you have authority to temporarily isolate TPWS and enter at caution completing the ticket instructions.

The entrance and exit signals are held at danger with a detonator which is removed after issuing RT3184 and displaying yellow flag or after having RT3184 returned and displaying yellow flag.

At the exit signal, return RT3184 to hand signaller, reinstate TPWS, wait for signal to clear, detonator to be removed and yellow flag shown before proceeding past exit signal.
