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.
What are the financial implications of delays caused by incorrect stoppings?
Financial costs due to delays.
This can affect overall operational budgets.
What is a potential risk of incorrect train movements?
Collisions with other trains.
This poses a serious safety risk.
What is a risk to passengers on the train due to incorrect stoppings?
Injury to people on the train.
Safety of passengers is a primary concern.
What should you be aware of after bringing your train to a stand?
You need to be aware of train movements that may occur after your train has stopped.
What may the signaller authorise after your train has stopped?
The signaller may authorise another train to enter the section behind you or signal the train ahead of you to depart the platform.
What are some risks associated with train movements in occupied platforms?
Risks include:
- Not knowing which movement authority applies to you and your train
- Moving without authority
- Not moving when authority is given
- More than one train moving at a time, causing conflicting movement.
How are risks heightened at platforms?
Risks are heightened at platforms where bi-directional permissive working is in operation.
What should you know regarding movement authority?
You should know how the movement authority will be given.
When should you move your train?
You should only move when you have reached a clear understanding about how your movement will be authorised.
What should you do if you are unsure about the movement?
You should stop your train if you are unsure about the movement or if you notice conflicting movements.
What action should you take if there is any risk to anyone?
You should stop if there is any risk to anyone.
What must not be done once the train has come to a stand?
You must not make any movement, other than for coupling or uncoupling.
When is movement permitted after a train has come to a stand?
Movement is permitted if:
➢ A signal is cleared for the movement
➢ The movement is authorised by the signalling system
➢ The movement is authorised by the signaller
What must you do if the movement was made on the authority of the signaller?
You must tell the signaller when the movement has been completed.
What is the maximum distance for a setting-back movement when coupling or uncoupling?
The movement must not be greater than 2 foot.
What should you do if the movement needs to be greater than 2 foot?
You must get authority from the signaller.
What must you do when driving a train towards the rear of another moving train?
You must:
❖ Proceed at caution
❖ Keep sufficient distance to prevent collision
❖ Not pass a signal cleared for the train in front until it has been returned to danger and then cleared again.
What should you know about the train when approaching terminal stations and buffer stops?
You need to know if the train fits, which will be known from route knowledge.
What are the EMR speed rules when approaching buffers?
The speed limit is 10mph to buffers.
What should you consider regarding signals when approaching terminal stations?
You need to decide whether to proceed cautiously by PL or subsidiary.
What geographical feature should you consider when approaching terminal stations?
You should check if there is a gradient.
What potential issue on the platform should you be aware of?
Be aware of any distractions on the platform.
What conditions should you assess regarding the track?
You should consider railhead and weather conditions.
