Permissive Flashcards
What indicates that a platform ahead is occupied?
The signal before the platform will display a ‘stop’ indication.
How can movements into an occupied section be authorised?
Movements can be authorised using a PL associated with the main aspect or a semaphore subsidiary signal.
What does proceeding at caution mean?
Travelling at a speed where you can see the line to be clear; able to stop short of any train, buffer stops, signals or obstructions.
What must you be able to do if approaching on a bend or with poor visibility?
You must be able to stop safely in the distance you can see to be clear.
What should you do if you need to stop behind a train occupying the platform?
Proceed carefully towards the train and stop at least 6 feet away from it.
How should you control your speed when approaching a train in front?
Bring the train to a gradual and smooth stop.
What should you do if there is a risk of low adhesion?
Reduce your speed earlier and bring the train to a stand progressively.
Who may signal you to a stopping point?
Platform staff may signal you to a stopping point.
Where should you stop if car stop markers are provided?
Stop at the relevant marker for your type or length of train.
What additional information might the sectional appendix contain?
It may have local instructions regarding stopping procedures.
What is Permissive Freight (PF)?
Permissive Freight (PF) refers to a type of permissive working.
What is Permissive Contingency (PC)?
Permissive Contingency (PC) refers to a type of permissive working.
What is Permissive Sharing (PS)?
Permissive Sharing (PS) refers to a type of permissive working.
What is Permissive Platform (PP)?
Permissive Platform (PP) refers to a type of permissive working.
What is Permissive Attaching/Detaching (PA)?
Permissive Attaching/Detaching (PA) refers to a type of permissive working.
What is Permissive Emergency (PE)?
Permissive Emergency (PE) refers to a type of permissive working.
What are the risks of stopping short of the correct stopping position on an occupied platform?
Movements stopping short of the correct stopping position.
This can lead to the rear of the train not platformed.
What can happen if doors are opened but not accommodated?
Death or serious injury.
This is a significant risk if the train is not properly positioned.
What are the consequences of extending movement beyond the correct stopping position?
Having to set back to the correct position.
This can cause delays.
What delays might occur when needing to set back?
Delays due to contacting PIC to obtain authority to set back.
This can further complicate operations.
What issues can arise from incorrect stoppings?
Other trains unable to occupy platforms due to incorrect stoppings.
This can lead to a chain reaction of delays.
