What must a driver do if encountering a defective Automatic Train Stop?
Report it to Train Controller at Metrol.
Unless faulty, what position must the train-mounted trips be in?
Leading cab trip must be lowered, all other trips must be raised.
What is a “back-trip”?

- Proceed with Extreme Caution to next fixed signal
- Incident Report
If a driver has tripped in the vicinity of a Home or Dwarf signal, when can they move the train?
After they’ve received the correct authority from the Controlling Signaller or Train Controller.
If controller/s unavailable, train cannot be moved
When can a driver move a train after unintentionally tripping in the vicinity of an Automatic Signal?
If authority can be received, proceed as per Rule 1 Section 3.
