Q

What will a Train Controller do when Train Overtime in Section has been implemented?

A
  • Prevent any movement of trains in area
  • Inform station and signalling staff at ends of section
  • Locate train through any means possible
  • Keep trying to communicate with driver
25
Q

A
  • Stop train and check for signs of derailing
  • Call Train Controller at Metrol – give location, signal no, and whether it is in vicinity of signal
  • make a PA
  • Look for cause of trip
  • Reset trip
  • Proceed with extreme caution to next fixed signal
  • Incident Report to correspondence box
26
Q

Who do you call if your train trips in the vicinity of a Home, Disc or Dwarf signal?

A

Controlling Signaller

27
Q

How are signal diagrams read?

A

Like a map, with FSS always on the left

28
Q

Where can a driver be informed that a new signal diagram has been issued?

A

Under “The Depot” > Passenger Network Operations > Signal Diagrams

29
Q

Look at your signal diagrams for how we can identify Home, Automatic and Dwarf signals on a signal diagram. Maybe have a go at drawing them yourself :-)

A

Okay

30
Q

Where will a driver receive notification of signals being out of use? (3)

A
  • WON (Weekly Operational Notice)
  • Safe Working Circulars
  • Depot Notice Boards
31
Q

If a signal is to be permanently removed, what must be updated to reflect this change?

A

Signalling diagrams

32
Q

How is a Fixed Signal identified as being Out Of Use?

A

A black cross placed in front of each light, with the light extinguished

33
Q

When might an Out Of Use signal be bagged instead of crossed?

A

When it is a new signal that hasn’t yet been commissioned for service

34
Q

What does a driver do when they encounter a signal that has been marked as Out Of Use?

A

Disregard the signal

35
Q

What should a driver do if they arrive at a signal that has been booked as Out Of Use, and it is illuminated?

A

Treat it as a signal irregularity (i.e. stop) and report it to Train Controller at Metrol

36
Q

Can multiple signals of the same class be placed on the same pole?

A

Yes

37
Q

Can multiple signals of different classes be placed on the same pole?

A

yes

38
Q

What is indicated when there are multiple signals of the same class on the same pole?

A

Several routes are available to your train from that signal (no. of signals indicates no. of routes)

39
Q

In what order are multiple signals read?

A

Top to bottom, left to right

40
Q

What are the three reasons given in the courseware as to why signals are arranged top to bottom, left to right?

A
  • To give driver info regarding which route has been set
  • To advise driver if a route has been set on a line that is occupied
  • To make signals more visible
41
Q

If different classes of light are present on a two-position signal post, does this indicate how many routes are available to the driver?

A

Not necessarily – a calling-on signal will not indicate an additional route

42
Q

When is a Co-Acting Signal used?

A

Where a signal can’t easily be seen due to obstruction

43
Q

How is a Co-Acting Signal indicated?

A

With a letter “P” after the signal number – it will share a signal number with its paired signal

44
Q

What must a driver do if a Co-Acting signal displays a conflicting signal aspect?

A

Treat both signals at safest aspect (Stop). Contact Train Controller/Controlling Signaller

45
Q

Can Co-Acting Signals be read as separate signals?

A

No

46
Q

What is a PAE Cat-A?

A

Running a red without prior braking.

A train has proceeded without authority onto a running line, occupied track, work site, inactive level crossing or is now in conflict with another train movement.

47
Q

What is a PAE Cat-B?

A

Driver has tried to prevent PAE but wasn’t able to

From courseware: “Train has exceeded limit of proceed authority or proceeded without proceed authority on or onto a running line other than roll back.”

47
Q

What is a PAE Cat-C?

A

Driver has exceeded limit of proceed authority where:
- Rear of stationary train rolls back, resulting in prior section becoming re-occupied OR
- PAE has happened within a yard and has remained in a yard OR
- Other incidents not falling under Cat-A or Cat-B

47
Q

What is a PAE Violation?

A

Where the driver does not follow the correct rules after having a PAE

48
Q

What are the instructions a driver must follow after having a PAE? (5)

A
  • Immediately bring train to stand and into Emergency
  • Assess for potential risk to other trains
  • If risk present, make a REC call
  • Contact Controlling Signaller, Train Controller and provide the required information
  • Do not move the train unless instructed
49
Q

If a PAE has occurred, what information might the Senior Network Controller ask for? (10) (You probs don’t need to memorise it all, but good be be vaguely familiar with)

A
  • Name and employee number
  • Shift no
  • Leading motor number
  • TDN
  • Location
  • Signal no
  • Distance travelled on PAE
  • If braking had been applied prior
  • Fit for duty considerations
  • Any other questions
50
Q

When can you move a train after a PAE, and how far can you go?

A

Once you have been instructed, and only as far as you’ve been authorised.

51
Q

If a driver is to be relieved after a PAE, a driver will return to Flinders St to: (3)

A
  • Drug and alcohol test
  • Incident Report
  • Schedule a post-PAE interview
52
Q

What are the typical errors leading a Start Against Signal PAEs? (6)

A
  • Assuming a proceed signal without checking
  • Not moving reverser into Off/Neutral at stop
  • Moving the reverser without looking at the signal
  • Looking at the wrong signal
  • Distracted
  • Did not remember previous signal
53
Q

What can a driver do to remember if they have passed a Warning aspect and the next signal is not in clear view?

A

Use the Memory Aid Device

54
Q

According to courseware, what techniques can be utilised to help avoid PAEs in the section? (7)
(again, be familiar, you don’t have to memorise)

A
  • Reduce speed at warning signal/ MAD button
  • Plan to stop prior to signal
  • Be aware when approaching signals in unfamiliar areas
  • If uncertain of location of signal, brake
  • Next signal may have restricted sighting – don’t wait until you can see it before you reduce speed
  • Allow for wheel slip
  • Focus on red ahead
55
Q

What are the four typical errors when running under restrictive aspects:

A
  • Assuming aspects will improve
  • Not proactively slowing train
  • Not responding to warning aspect (pretty much same as above – wyd courseware??)
  • Lack of concentration
56
Q

How does a signal become a Multi-PAE Signal?

A

If it is passed 3 times within a 5-year period

57
Q

How long does a signal retain its “Significant” or “Extreme” risk status?

A

Two years – if it is PAE-free for this period of time it is reclassified to normal
