Q

How many times may a fault be rectified (RIR)?

(Not highlighted)

A

A fault may be reset three (3) times. After that, the defect must not be rectified by the Driver unless attempting to clear the main line after being totally disabled.

To ascertain the number of times a specific fault has been reported as rectified in running you should contact the TSO-PDS.

Q

Another Cab Operative (when there actually isn’t) Rectification

A

Make a cab-to-cab call to attempt to locate another Driver
Inspect each trailing cab for a key in the reverser or a cleaner’s key being active

If no key is found, activate each cab to attempt to ascertain which the active cab is, then deactivate it. This process could rectify the fault by energising and de energising the Other Cab Operative alarm system.

If none of the Master Key Switches are defective and the Other Cab Operative light still remains illuminated, perform a Train Stable for fault rectification procedure

If this fails to rectify the fault, the train can only be driven from the active cab.

Q

Pantograph Faults
IF the “High Voltate Present” light fails to illuminte in (how long?),it may be an indication of what?

What should you check?

A

30 seconds, it may be an indication that the pantograph has failed to make contact with the overheads.

First check the voltmeter for above 90volts
If there is not voltage at all
- Check the position of the baterry box isolation switch
- If isolated, call fleet and report via TMM
- If not isolated, declare train disabled.

If there is less than 90v
- Declare train disabled

If there is voltage above 90v

  • Check the Local and Trailing Panto control buttons are not latched in
  • Check teh 22q11 MCBB (Panto command) in Moter car
  • Attempt to raise pantos from another cab.

If THAT fails

  • Proceed to the trailer car and inspect the 3 was position, needs to be in Automatic (But you may not adjust this switch)
  • Inspect the panto circuit breakers in the trailer cars
  • Book as per FMP

Q

Isolating Pantos
What do you need to do?

A
  • Always stable the train first
  • Observe the defective panto has lowered

If it does lower

  • Proceed to the relevant trailer and place the 3 way switch to manual lowering and isolated position
  • Activate the leading cab to raise the other panto
  • Report as per FMP

If stabling does not lower the panto, it needs to be manually lowered

  • Proceed to the relevant trailer and place 3 way switch to mainually lowering and isolated.
  • Attach the crank handle to winder.
  • Wind in anti-clockwise until tension is felt
  • return the crank handle to the holder
  • Confirm panto is lowered (observe)
  • Book as per FMP

(remember this means the 3 car unit with no panto is running on batteries (60m)

Q

How do you coast under a section with an overhead obstruction?

A
  • Panto test to make sure panto’s lower in time (10s)
  • Raise the panto’s again, if test failed confer with TC
  • Move master controller to full service, switch to EMS 1
  • Apply sufficient power to enabel train to coast under obstruction. (Fucking floor it)
  • Lower pantos, pray they lower in time
  • When all T-cars clear the first stanchion after the crossing/obstruction bring train to a stand.
  • Put EMS back to 2
  • Ensure all T cars are clear, raise pantos (unlatch)

Note: If only the lead car clears the obstruction, you may raise the local panto and drag the train forward before raiding the trailing panto.

18
Q

What are all the positions of the Door Motor Isolation Switch?

A

1 - Motor release

2 - Motor Isolate

3 - Normal

4 - Motor Lock Close

19
Q

Flashing Door Close Light occuring between stations

A

Make a PA
Example “All customers please stand clear of the doors and please remove any job objects from the doors”
If you’re on empty cars, assume you have somebody on the train.
Check for DER light
If FDCL is not caused by DER, continue ruinning to the next station, reg ardless of timetable

While on the way to the next station, reduce speed and watch mirrors for objects/people hanging out of a door.
At the next station, release the doors as normal. make a PA. Close the doors when safe.
If the door close light steadies, the train may continue.

20
Q

If your FDCL does not fix at a station, what do you do next?

A

Release the doors
Make a PA asking passengers to stand clear and remove objects.
Check DER
Log call to TC ( TEC)
Make another PA asking any customers who can hear the door tone or see an open door to press the PEI because we can’t move until the doors close.

FAULT FIND

  • The door tone will sound for 60s
  • Full cab unattended, hit the releasing and closing the doors before exiting the cab. (to reset the 60s)
  • Take portable and “door not in use” sticker/tmm book.
  • “Briskly walk” along the train listing for door tones or looking for the open door.
  • If you find door, close and isolate the door.
  • If you reach the back 3 units, enter center cab to reset door tone timer
  • Same thing to the Trailing cab.
  • If you reach trailing cab, put key in to check if FDCL status.
  • If you have not found the door, you must detrain and shunted.

IF this is the last service of the night, call PD’s for more fault finding, they don’t want to pay for taxis.

  • If detraining, lock doors at rear cab, walk through cabs to ensure nobody is in train.
  • When ready to shunt empty train, turn the Door loop bypass in the MCB
21
Q

How will the driver know if there is a DER activation?

A
  • Flashing Blue Door Closed light
  • Door Emergency Handle Activated status light illuminates
  • Flashing Red ANSW Acknowledge button
  • DDU emites beep sound
22
Q

What are the drivers actions when the DER activates?

A

Establish which DER handle has been operated from the DDU
Conduct full cab unattended
Reset DER with trikey
Report the broken DER seal as per FMP

If the DER activated due to a door fault, isolate the door.

23
Q

How does a driver isolate a door?

A

Locate the door, when advised by TC
Open the overhead cabinet to the left of the door.

Move the motor isolation switch to Motor Release (position 1)
Manually close the door (by hand)
Move the motor isolation switch to motor release (position 4)
Apply door nopt in use sticker

Book TMM

24
Q

What could be the issue if you open a cab door during a prep and find your step light not illuminated?

A
  • Bulb in the light needs replacing
  • Batteries are flat
  • Batteries have been left isolated
  • Battery box fuse is blown/missing
25
Q

If you put your key to start up the xtrap, and you find 0 volts on the voltmeter, what do you do?

A

The driver is to check the battery isolation switch, to ensure it is ON.
If the switch is found to be ON. You can assume the train has a flat batter or fuse blown. The defect is to be booked as per FMP

If battery is in isolation call Fleet

26
Q

Which lights would show up if you have a Battery charger fault? (assume no circuit breaker)

A

High Voltage presence

Battery Charger Fault

( If you have a battery charger issue Hvac 1 and 2 will be off too)

27
Q

What lights will appear if there is a traction equipment fault on a center or trailing cab?

What will they get if it’s in the lead cab?

A

If the fault is in any other cab
- 1 or more traction equipment fault light (train lined)

If the fault is in the cab the driver is in, they will see both
- Traction Fault light

  • 1 or more traction equipment fault light (train lined)

If you are in the lead cab and see both lights, turn the Traction Isolate switch.
If you only see 1 or more traction light, next time you are changing ends on the train, enter center and trailing cabs and insert key to see which cab has both lights and turn the switch

28
Q

How does a driver know if all speed probes have become defective, as opposed to only one or two?

A

If All are defective, the driver will not be able to operate the doors and will have no electric speedometer. DUCTs will not work
