Q

Which personnel do not fill in a RT3181 form?

A

Station staff
Train crew
DP designated person

23
Q

Why might you need a line blockage for 13.1?

A

Personnel might need to work on the outside of a train stopped on a running line because of failure or other incident

Driver asks you to block line for them or other staff to walk alongside their train

A DP needs to walk with a group to a failed train or other incident

Member of station staff asks to go onto the line at a station platform to retrieve items

24
Q

What must you say to a person receiving a line blockage under 13.1?

A

The line will stay blocked until person tells you that the line blockage is no longer needed

Any other lines that could be still running trains

25
Q

What must you agree with a COSS etc before granting a line blockage

A

Nature of work

Exact location of work

Length of time needed

Time after which blockage can be granted

Arrangements for leveling crossings that will be affected

Do they require any additional protection

What the protecting signals are

The line to be blocked

Any single line arrangements

26
Q

Forms of protection in a line blockage

A 
T-cod
Take the token
Disconnect signals
Detonators
EPR engineering possession reminder
27
Q

If the work is within 200 metres of protecting signal and affects the safety of the line what must you do?

A

Use the signal previous to protecting signal as a MAD signal

28
Q

What must you do with the first train passing after a line blockage that has affected the safety of the line

(also a ibh signal)

A

Watch the track circuits to make sure they operate correctly

Section signal cannot be cleared for a second train to approach a ibh signal until train out of section is sent for the previous train

29
Q

What must you do when signalling equipment fails?

A

Make operational railway safe

Tell any other signallers involved

Tell ops control

Make sure trains pass safely

Enter details into trb

30
Q

When can you allow a driver to approach a defective signal (generally)

A

May approach a defective Stop Signal if it is placed in the on/danger position and you are sure the correct aspect is showing

May approach a defective distant signal
If it is set to caution and you are sure the correct aspect is showing

May also allow a train to approach a defective signal if you have made sure the correct proceed aspect is shown, it will not cause the driver to see an incorrect sequence and one of following applies

The line is clear to the buffer stops of a dead end

The train has been accepted to the box in advance (when necessary)

The line is clear up to and Including the overlap of a ibh signal.

The defective signal is in between the home and section signal and the line is clear up to the section signal

31
Q

What must you do with a defective ibh signal

A

Must make driver aware of the fault at the section signal before approaching regardless of the aspect showing

Get line clear from box in advance

32
Q

What is a complex failure and who takes responsibility

A

Failure of power operated points which needs more point ends to be set or secure than a simple failure

Includes all failures that affect switch diamonds and swing nose crossings

Goes through a route setting agent RSA

33
Q

What is a simple failure

A

Failure of power operated points that needs-

Single point end

Single point to end and Co acting trap point

Both ends of a cross over

34
Q

WHIP for passing signals at danger

A

Why
How far
Infrastructure
Proceed at caution

35
Q

Who can give a driver authority to pass a signal at danger

A

Signaller

Shunter acting on signallers instructions

Pilotman or hand signaller acting on signallers instructions

Another competent person

36
Q

If you can, when must you operate the signal lever concerned if the signal is to be passed at danger?

A

The signal is: defective

Disconnected

Cannot be cleared because signalling equipment has failed

37
Q

If you cannot operate the lever or the signal is to be passed at danger for any other reason you must

A

Reverse all levers that usually release the signal lever concerned

Normalise all levers that usually lock the signal lever concerned

38
Q

If the interlocking is out of order you must make sure

A

The facing points on any other line are set to avoid conflicting movements normally prevented by the interlocking

Signals for conflicting movements are at danger

Routes for any conflicting movements are at danger

39
Q

Before you authorise a wrong direction move you must make sure that

A

Barriers or gates at any controlled level crossings are closed to road traffic

Any automatic half barrier crossings without wrong direction controls are locally operated

All points are in the required position and locked by facing point locks where provided

Any unworked points are secured (trap, catch)

Any ground frame release giving access to the route is normal unless it is needed for the movement

40
Q

What must you do with the first train on the adjacent line which could be fouled by the movement being set incorrectly during wrong direction moves?

A

Stop any train until the wrong direction move is complete, you may start running trains once you know the wrong direction route is set UNLESS you change the route after the first wrong direction

41
Q

When do you not need to make sure the line is clear for 400 metres beyond the signal the movement is taking place to?

A

When the movement is proceeding towards:

Stationary train

Point of Obstruction

Detenators protecting possession

Beyond the point at which it will return to a line in the right direction

42
Q

What must you instruct a driver when carrying out a wrong direction move

A

What is required

How far the movement will go

Check where possible, that points and crossings are set correctly for movement

That any unworked points are secured (trap, catch)

Proceed at caution

Arrangements at level crossings

43
Q

When it is necessary for an assisting train to proceed through one or more sections in the wrong direction

Over the unaffected line to assist a failed train from the front

Over the unaffected line line to assist a failed train beyond the failed train in the normal direction

Over the affected line towards the failed train where no crossover is available at the signal box immediately beyond the failed train in the normal direction of travel

49
Q

When must you not use working in wrong direction reg?

A

During a signalling equipment failure (block instrument) and you don’t have communication available with the boxes concerned

50
Q

Head code for a OTM “train that cannot be relied upon to operate track circuits”

A

1Z09

51
Q

When must you class a normal running train as ‘train that cannot be relied upon to activate track circuits’

A

If a train loses 2 carriages worth of actuators from the front or the back

52
Q

Where can you stop a train that cannot be relied upon to operate track circuits?

A

Only at a signal you can physically see from your box

53
Q

PUBAG for arrangements before allowing a wrong direction move

A

Points are in correct position and locked by facing point locks where provided
