General Fault Finding Flashcards
What are the two types of faults? (not categories)
- Persistent
- Intermittent
What are the safety-critical faults that appear on the Fault Warning Notice book? (5)
(side note, it’s dumb we highlight/memorise this because in the field we would just look at the literal book)
- Bogies Isolated
- Airbag deflated
- Lateral sway fault
- Red EC/Yellow TECHAV isolated on a lead/trail motor
- Doors isolated
(BALRD - as in, let me sing you the BALRD of Safety-Critical Faults that Appear on the FWN book)
Three indications of a defective whistle are:
- Sounding continuously
- Not sounding
- Tone too low
How might a driver remedy a whistle sounding continuously or a whistle failing to sound?
Operate the whistle lever several times
If a whistle fails in service, what speed restrictions apply?
Reduced speed cautiously
If a whistle fails in service, what precautions must a driver take when approaching level crossings/persons near the line?
Alternate headlights between high and low, or use hazard lights if available
True or false:
When a whistle fails in service, a driver is required to pass level crossings with a speed restriction of 15km/h
False – it is reduced speed cautiously with use of high/low beams or hazard lights
If a whistle fails in service, what speed restriction is applied through yards, stations or near employees/track workers?
15km/h
How is a driver to operate if their whistle is a lower tone than normal?
Train will operate as normal, but a TMM must be submitted
Daylight hours:
If both headlights are defective but white marker lights are operational, what speed restrictions apply?
Maximum 50km/h through MURL and West Richmond tunnels
What restrictions must be adhered to in the hours of darkness if both headlights are defective? (5)
- White marker lights must be operative
- Advise train controller at Metrol
- Nor exceed 50km/h between stations/crossing loops
- Not exceed 15km/h through level crossings, stations or yards
- Make frequent use of the whistle (particularly near pedestrian/level crossings)
What category of fault is both headlights defective during hours of darkness?
Critical (must be removed from service or re-marshalled if time permits)
What is the maximum speed of a train when skidding jammed/locked wheels to clear a section?
5km/h
If a train is skidded clear of an area, infrastructure personnel will attend and examine the track. What guidelines will the personnel put in place?
All following trains must be stopped, or travel at reduced speed, until the track is deemed to be safe.
(This questions is shonky but I couldn’t think of a better rewording)
If a train is skidded clear of an area and infrastructure personnel are NOT available, track force protection will attend. How will track force protection advise use of the track?
Train Controller will arrange for track force protection – flag signaller will instruct drivers to proceed cautiously not exceeding 15km/h until track is rectified fit for operational use
Isolated Bogies:
What percentage of bogies must be available for a train to remain in service?
50% of greater. If lower than 50% train is declared disabled.
If number of isolated bogies equates to having between 50% to 80% of a train’s breaking power available, what speed restrictions apply?
Train must not exceed Extreme Caution
What must a driver do if the FDCL continually flashes between platforms? (5)
- Make PA requesting passengers stand clear of doors
- View mirrors for passenger safety
- Reduce speed
- Advice train controller of situation
- Stop train at next platform (regardless of conditions)
What service restrictions apply if a train’s window is externally cracked?
Train may remain in service
When a train has been combined in case of a fault, what speed restrictions apply if the train is powered and braked from the leading motor?
Reduced speed
When a train has been combined in case of a fault, what speed restrictions apply if the train is powered from leading cab but braked from a trailing cab?
15km/h maximum
When a train has been combined in case of a fault, what speed restrictions apply if the train is braked from leading cab but powered from a trailing cab?
40km/h maximum
(from courseware)
Some defects that can occur to pantographs include but are not limited to: (7)
- Worn/damaged carbon strips
- Damaged panto heads
- Damaged panto arms
- main res leaks
- electrical defects
- end of overhead overruns
- disarranged overhead wires
(from courseware)
Damage that can occur to pantographs heads can include: (6)
- Broken wires
- Damaged/broken/missing carbon strips
- damaged horns
- twisted/bent/damaged frame
- foreign object entaglements
- excessive arcing
If a driver observes defects in upcoming overheads, what must they do?
Use emergency brake to stop short of defect, and lower all pantographs if unable to stop in time
What is the maximum time allowance required for pantographs to be lowered from the lead cab?
10 seconds
After stopping their train, what is a driver’s responsibility to seeing disarranged overheads? (3)
- Make emergency call to Metrol
- Do not exit cab
- Make PA announcement informing passengers of situation
If a train lowers its pantographs to coast under a section of overhead, what type of breaking is available to all trains?
Friction breaking
When coasting under a section of overhead, what must a driver do if a driver is only able to clear their leading pantograph under the obstruction?
Raise the lead pantograph only and pull the train through to the next platform.
How are pantographs raised on a Comeng train?
Pneumatically, using main res air
What kind of power is used to raise pantographs on a Siemens train?
Electric motor and battery power
What kind of power is used to raise pantographs on an Xtrap train?
Electric motor and battery power
What kind of power is used to raise pantographs on an HCMT train?
Electric signal and pneumatic power
