If a whistle is sounding continuously what can you do to fix it?
Operate lever rapidly several times
Or if that doesn’t work…Isolate
If a whistle fails to sound, what can you do to rectify?
Operate lever rapidly several times
Check isolating cock and any relevant circuit breakers
If a whistle fails in service, what restrictions are required? (4)
- May need to rerelease doors at platform
- Travel at reduce speed cautiously and 15km/h through yards, stations, level crossings or near track workers
- High/low beams at level crossings and near track workers
- Reduce speed or stop if vehicles/person on/near line are not aware of trains approach
If the train whistle tone is too low, can the train continue in service without restrictions?
Yes, if it is still effective
If a Leading Motor has a whistle failure what can be done to rectify it (time and space allowing)?
Remarshall

Low beams
If one headlight is defective, are there any operating restrictions?
No, train may remain in service without restriction
If both headlights are defective during daylight hours, are there any restrictions?
50km/h in Loop and West Richmond Tunnel only
If both headlights are defective in hours of darkness, what category of fault would this be?
Critical unless it can be remarshalled - becomes maintenance
What restrictions are in place if both headlights are defective during hours of darkness? (4)

What is the max speed a train with locked/jammed wheels move at?
5km/h
Once a train with locked/jammed wheels is moved, what will infrastructure personnel implement?
All following trains must be stopped, or travel at reduced speed until track is deemed to be safe
If infrastructure personnel are not available to inspect track after locked/jammed wheels what will TC implement?
Track force protection
15km/h until track is certified safe
If a train has up to 20% of it’s bogies isolated, what restrictions are in place?
60km/h or below - Track Speed
Above 60km/h - reduce by 10km/h
If train only has 50-80% of braking available, what restrictions are in place?
Speed is - Extreme Caution

Train is declared disabled
If a saloon window is damaged and the film isn’t penetrated, can it remain in service?
Yes
If a saloon window is damaged and the film is penetrated, can it remain in service?

No, only the same EMU can couple electrically
Who fits transition couplers?
Maintenance personnel only
If a combined train is braking and powering from the lead, what restrictions are in place?
Reduce speed cautiously
If a combined train is braking from the lead but powering from another cab, what restrictions are in place?
Max speed of 40km/h
If a combined train is braking and powering from a non lead cab, what restrictions are in place? (Propelling)
15km/h max
In a combined train, what cab has the trip lowered?
Lead Cab
How can you communicate with a Competent employee during train rescues? (4)
DTRS
Cab to Cab
Hand Signals
Bell/Whistle Codes
What damage can occur to a Pantograph? (6)
- Broken wires
- Damaged/missing/broken carbon strips
- Damaged horns
- Twisted/bent/damaged frame
- Foreign object entangled in pantograph
- Excessive arcing
What can excessive arcing be an indication of?
Pantograph defect
If you spot a defect/damage in the overhead, how must you react?
Emergency brake to stop short of
Lower pantographs if unable to stop short
If the overhead is disarranged, what must the driver do immediately?
REC to TC
Do not exit cab (assume live wires)
PA
What must be performed before coasting under obstructions/tramways?
Pantograph test
Once pantographs are lowered, what brakes are still available?
Friction only
If the carbon strip is damaged on the pantograph, what must you do?
Lower and isolate, book fault
How does each train type raise pantographs?
Comeng/HCMT - Pneumatics
X’Trap/Siemens - Electric motor/battery power
If you have a flashing blue door light between stations, what must you do? (6)
- PA
- View mirror - stop if anyone protrudes
- Reduce speed of train
- TEC call
- Stop at next station (regardless of stopping conditions)
- Initiate door closing sequence
How do you rectify a flashing door close light at a station? (5)
- PA
