week 6 test

Question 1

When do you send Obstruction danger?

Answer 1

If you need to stop trains from signal box in rear because of a Obstruction or emergency within clearing point at your box

Must do this no matter where your block indicator is

Question 2

When do you not need to send Obstruction danger

Answer 2

Obstruction is beyond clearing point

There are facing points you can immediately set for another route clear of the Obstruction and that route is clear to the clearing point

Question 3

Other instances to send Obstruction danger

Answer 3

Train out of section not Received

Is line clear not Aknowledged

Train proceeding without authority in right direction not Received

Shunting move not Aknowledged

Question 4

What must you do after you have sent/received Obstruction danger

Answer 4

BITOL (if not all ready there) until the Obstruction has been removed

All signals leading to the Obstruction back to danger to protect Obstruction

Attempt to stop any trains (emergency call)

USE REMINDERS

Reply with 6 or 4-5-5 depending on situation

Find out/tell other signallers why the bells were sent and reach a clear understanding of those lines that must remain blocked and those that can be re-opened

Question 5

If you have received Obstruction danger and you have stopped a train in your section what must you do

Answer 5

Cancel the train, Block indicator will remain at TOL

Question 6

Bell code for Obstruction removed, proceeding in right direction, wrong direction and cancelling

Answer 6

Obstruction removed 2-1-2

Proceeding without authority right direction 4-5-5

Proceeding without authority wrong direction 2-5-5

Cancelling train 3-5

Question 7

If a train is in the same section as the Obstruction danger when can you send train out of section?

Answer 7

You don’t, you must send Obstruction removed 2-1-2 once both the Obstruction as been removed AND the train has passed beyond the clearing point CWTL

Question 8

When do you block back during Obstruction danger?

Answer 8

If you need to alter the facing points at a junction to allow a train to pass over the junction from another direction meaning the Obstruction would now be in the clearing point you must first block back inside the home signal (2-4)

Question 9

Bell code for train passed without tail lamp box in advance

Answer 9

9

Question 10

Bell code for train passed without tail lamp box in rear

Answer 10

4 5

Question 11

How may you know a train has passed without tail lamp?

Answer 11

Ops control

Station staff

Track workers

Physically looking out of window

Bell codes

Question 12

Why do you check for tail lamp?

Answer 12

Physical indication that whole train has made it out of the section

Allows us to send train out of section 2-1 and place Block indicator to normal to be able to be offered another train

Question 13

Where must block indicator remain after you have sent 4-5 passed without tail lamp to box in rear and when will it change?

Answer 13

TOL until driver, signal box in advance or train going in opposite direction has contacted you/gave you indication that the line is clear (when you can give 2-1 train out of section to box in rear)

Question 14

What must you do if train passes with a tail lamp but the light is out?

Answer 14

Send train out of section as normal

Send 9 bells to box in advance (after train entering section)

Inform box in advance that the lamp is out

You do not need to caution trains on opposite line

Question 15

What precautions must you take before allowing a signal to be passed at danger?

Answer 15

The portion of line is clear and it is safe for the movement

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

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

Any ground frame release is normal unless needed for movement

Question 16

What must you tell a driver when authorising them to pass a signal at danger? (other than single line working in wrong direction and block instrument failure)

Answer 16

Why the signal must be passed at danger

How far the movement can proceed

Proceed at caution

Pass any SPAD indicators which may illuminate

Check and to approach at caution and check that it is safe to pass over any:
Controlled level crossings

Automatic level crossings that will not operate normally for the movement

Barrow or foot crossing with white light indicators that will not operate normally for the movement

Question 17

2 occasions you can use restricted acceptance

Answer 17

Single line working

Engineering train Is to enter a t3 possession of the line with a work site marker board within the clearing point and the line is only clear upto the home signal

Question 18

When will train out of section be sent during restricted acceptance and where will block indicator be placed?

Answer 18

When the train has passed the home signal, Block indicator remains train on line

Question 19

What must you say to a driver that has been accepted under restricted acceptance?

Answer 19

You have been accepted under restricted acceptance only as far as the home signal.

Only say proceed at caution if you are authorising a signal passed at danger because line clear could not be given to clear section signal

Question 20

Methods of contact for a driver to signaller

Answer 20

GSMR

CSR

Mobile phone

Line side telephone

SPT telephone

Another SPT

Driver going to signal box

Question 22

Which personnel do not fill in a RT3181 form?

Answer 22

Station staff
Train crew
DP designated person

Question 23

Why might you need a line blockage for 13.1?

Answer 23

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

Question 24

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

Answer 24

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

Question 25

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

Answer 25

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

Question 26

Forms of protection in a line blockage

Answer 26

``` T-cod Take the token Disconnect signals Detonators EPR engineering possession reminder ```

Question 27

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

Answer 27

Use the signal previous to protecting signal as a MAD signal

Question 28

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)

Answer 28

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

Question 29

What must you do when signalling equipment fails?

Answer 29

Make operational railway safe Tell any other signallers involved Tell ops control Make sure trains pass safely Enter details into trb

Question 30

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

Answer 30

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

Question 31

What must you do with a defective ibh signal

Answer 31

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

Question 32

What is a complex failure and who takes responsibility

Answer 32

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

Question 33

What is a simple failure

Answer 33

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

Signaller Shunter acting on signallers instructions Pilotman or hand signaller acting on signallers instructions Another competent person

Question 36

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

Answer 36

The signal is: defective Disconnected Cannot be cleared because signalling equipment has failed

Question 37

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

Answer 37

Reverse all levers that usually release the signal lever concerned Normalise all levers that usually lock the signal lever concerned

Question 38

If the interlocking is out of order you must make sure

Answer 38

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

Question 39

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

Answer 39

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

Question 40

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?

Answer 40

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

Question 41

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

Answer 41

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

Question 52

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

Answer 52

Only at a signal you can physically see from your box

Question 53

PUBAG for arrangements before allowing a wrong direction move

Answer 53

Points are in correct position and locked by facing point locks where provided Unworked points are secured Barriers or gates at Controlled level crossings are closed to road traffic AHBC crossings without wrong direction controls are locally monitored Ground frame releases giving access to the route is 'normal' unless required for the movement
