- yards
What must you do when approaching a level crossing and/or track workers when you have a defective whistle?
Flash headlight between high and low
What must you do if the whistle tone is too low?

- continue as normal
How many headlights must be operative to stay in service without restriction?
1
At what speed can you travel during the day time when both headlights are defective?
- no restriction outside
- 50km/h through MURL and west richmond tunnels
When/where must you do 50km/h when driving with both headlights defective?
- MURL
- west richmond tunnel
When both headlights are defective during the hours of darkness, what is your maximum speed?
- between stations and crossing loops -> 50km/h
- level crossings, stations, yards -> 15km/h
What colour and how many marker lights must be displayed on the front and rear?
- front -> 2 x white
- rear -> 2 x red
What 4 things could possibly cause locked/jammed wheels?
- seizure of a traction motor
- brake rigging/head failures
- axle box failures
- any other potential mechanical fault
What is the maximum speed when skidding wheels to clear the track?
5km/h
Can you move a train if the lead axle is locked?
No, unless returning in the other direction
What are some things you may see to indicate a locked/jammed axle?
- smoke
- fire
- hot when walking past
- retardation
If a train needs to be skidded clear of a section, what speed must be done by following trains?
- infrastructure personnel present -> reduced speed
- no infrastructure personnel -> 15km/h
What are the speeds associated with isolated bogies?
- > 80% braking -> -10km/h if speed >60km/h
- 50-80% braking -> extreme caution
- <50% braking -> disabled
If a HCMT has 3 or more bogies isolated, what will happen?
Removed from service
If there is a speed restriction associated with a fault, what must the driver put in each cab?
FWN and sticker
What are the 5 steps that a driver must do when they get a FDCL between stations?
- PA announcement, stand clear of doors
- view mirrors for passenger safety
- reduce speed of train
- advise TC of situation
- stop at next station regardless of timetable
What must you do if you have a FDCL at a station?
- PA announcement
- re-release doors to restart chimes
- check for defective door
- TEC call to TC to advise of situation
- re-open then close doors from centre cav to restart door chimes
- if fault can’t be found, door loop bypass and detrain passengers
How many doors can be isolated and the train be able to remain in service?
1 per side per car
If a cab door is found opened and unable to be secured, will the train be able to remain in service?
Yes if competent employee available to ride in cab
If a FDCL is able to be rectified, what 3 things must happen for the train to remain in service?
- blue door closed light is steady proving doors closed and locked
- only 1 per side, per car doors isolated
- door loop system not bypassed
How must you determine if a crack on a window is on the inside or outside?
Run the back of your nail ovet the window
How are windows numbered EMU trains?
- same as doors
- starting from 1 end A side in a clockwise direction
What will happen if the window crack is internal or external?
- internal -> competent employee to attend the window, otherwise out of service
- external -> remain in service until maintenance can inspect the window
During emergency conditions where the train needs to be moved, what are the speed restrictions (powering/braking location)?
- power and brake from lead -> reduced speed
- braking from lead, powering from other cab -> 40km/h
- braking and powering from cab other than lead -> 15km/h
What are 4 ways drivers can communicate with each other if the DTRS fails?
- cab to cab
- bells
- mobile phone
- hand signals
Can different train types couple electrically?
No, only mechanically and pneumatically
Within how long must pantos lower after pressing the panto down button?
10 seconds
What is used to indicate the overhead is going to run out?
Terminal stop sign
What must you do if the overhead is about to run out and you don’t think you’ll be able to stop in time?
- emergency brakes/try to stop beforehand
- lower pantos remotely
If you see an obstruction in the overhead, what must you try and do?
Attempt to stop prior
Can you raise pantos while in motion?
No
What must you do with the pantos before coasting under an obstruction?
Panto test and ensure they lower within the 10 seconds
What will happen to the saloon doors on a comeng if there is a loss of overhead power?
They will release
What are the 7 steps when you have to coast under an obstruction in the overhead?
- stop sufficient distance from obstruction
- PA announcement
- panto test
- raise pantos
- apply traction power
- lower train lined pantos
- stop train when clear
What are the 8 steps when you have to coast under a tramway square?
- stop prior to home signal at danger
- receive SCO for signal
- PA announcement
- panto test
- raise pantos
- apply traction power
- lower train lined pantos
- stop train when clear
If the train hasn’t fully cleared the obstruction/tramway square, what must you do?
Raise leading panto and move train until whole train passed first stanchion in the advance of the level crossing
If your pantos are lowered, will there be ED/rheo braking available?
No
What are 3 minor pantograph defects?
- worn carbon strips
- panto failing to raise
- pantos failing to lower
What raises the pantos on each train type?
- comeng + HCMT -> air pressure
- x’trap and siemens -> electric motor
If a panto fails to lower and cannot be manually lowered and isolated, can the train continue/enter into service?
No
If a panto can be isolated and there is no obvious damage, can the train continue in service?
Yes
