train stable HSCB light control
can’t get traction if it’s tripped in that unit
30
if you can’t reset friction brake and monitoring
safety loop bypass
31
safety loop MCB and Emergency brake valves MCB
cannot be bypassed- must be rescued if cannot be reset
32
automatic coupler control tripped in the
leading centre motor
it will be impossible to uncoupled if this is tripped in any unit
can be bypassed safety loop bypass
33
door control train lined MCB
if this cannot be reset the door close and lock and auto inhibit features will not operate. the door loop in this case cannot be operated the train must be rescued
34
door control power supply MCB
just means the door cannot get power/command from the door buttons

30 seconds for pantos to lower
ensure line voltage tile extinguishes
step light and spot light will remain illuminated for 5 minutes
39
‘brakes on’ train status tile illuminated while moving
indicates:
a brake has failed to release
40
isolating a bogie
RTA
Full cab unattended
locate affected unit
remove brake module cover
turn the cock to the isolate position
replace cover
report TMM to TC and cancel RTA
Operate in accordance with bogie isolated procedure
41
if there’s a fault with the bogie:
fault panel tile
once isolated train status tile will illuminate
42
Park Brake Defects:
attempt to release using the rotary switch
observe cab train man MCB is set
attempt to power against them- if it can be moved retrain and shunt ( but the safety loop will open if you exceed 5km/h with the park brakes on)
otherwise RTA look for air leak
submit TMM
43
how can you tell if the park brakes have failed to release?
the tile is illuminated
retardation
smoke/smell
44
how to manually release a park brake
(mindful the park brake will automatically reset after the next application eg. key out)
locate
isolate bogie
locate and unlock pin
pull manual release device until tension relieved
replace and lock pin
turn the bogie IC back
replace brake module cover
TMM
45
main res pressure at or above 600 (but below 850)
flashing uncouple button
report TMM
operate as normal
monitor duplex gauge
46
main res below 600
emergency brakes will apply
air suspension on both bogies must be isolated
max 80km/h
47
defective spring
remove from service
deflate both air bags on level service and look for a lean
48
defective dampener
report and book
49
if main res is a steady 700kpa
maybe the towing cock has been turned in that cab to the rescue position
50
main res defects cars 3&4
RTA identify leak attempt to blank the equipment, if unsuccessful:
RTA
full cab unattended
close end cockcs
manual release park brakes with the manual release devices
isolate safety loop bypass
drive in accordance with equipment isolated
detrain and remove from service
51
main res defect any car except 3&4
RTA attempt to blank the equipment
if it works confirm loss of equipment and TMM if not
isolate end cocks at both ends of the car, declare disabled, train must be sandwiched, if electrically coupled with a siemens the safety loop must be bypassed in the lead
once coupled: isolate bogie 1 and manually release SPB
repeat on bogie 2
52
spring park brake on trailer cars?
yes
53
main res pressure drops below 600 and compressor fault light tile illuminated
call TC request permission for train stable try train stable for fault rectification
if fault remains:
RTA
head to air compressor ( T car 1 end A side)
turn the pressure switch to isolate
if the compressor fails to start and main res stays below 600 declare disabled
54
when might a driver turn sanders IC
major damage has occurred to sanding equipment
major air leak from sanding equipment that results in low main res pressure and affects safe operation of the train
55
do you need to isolate an inoperative sander
no
56
how does the whistle work
a solenoid valve releases air to the whistle components so it needs and electrical circuit to operate pneumatic components
57
whistle sounds continuously
depress and release several times
trip and reset DCDC inverter wiper on affected car
58
whistle not sounding
depress and release the lever several times
inspect the whistle isolating cock
inspect windscreen wiper horn
inspect dc dc inverter front lights wiper
TMM
59
bogies isolated
80-100% 2 bogies on a 6 car : 10km less until 60km2h
50-80% 6-9 bogies on a 6 car : extreme caution
less than 50% disabled
60
FDCL between stations
PA
view mirrors
reduce speed
TEC
stop at next station regardless of timetable
61
pre movement /revenue
18 mins revenue is when it’s already been prepped
pre movement if it’s not fouling a running line /going outside station limits
62
there are usually station staff for an attach divide if there are none
it is Driver In Charge conditions
63
another cab active
investigate
check cleaners key etc try and activate and deactivate if it won’t trip out cab train manned
64
serious and serious priority needs to be fixed by the next day
end run is end of that journey and return is end of that peak
65
if it’s not possible to move the train inspect
friction brake monitoring in motor
static inverter monitoring in trailer car
66
master controller handle failure / the oh fuck procedure
move it to emergency
press ESB
park brake on
master key too off
67
headlight failure
external lights control MCB
external light supply MCB
DC DC inverter front lights wiper
If they’re tripped reset
use headlight switch
if not already tripped, trip and reset
68
fire on train
turn off the HVACs
evacuate at a station
advise and use DERs if necessary
69
skidding wheels / locked axles
permanent wheel slip light
retardation/ smoke/ smell / sound
- stop TEC RTA locate isolate bogie or SPB might not work, clear section at 5km/h cannot be moved if fault is on lead
70
locked axle or skidding week trains to do 15 until track has been inspector
71
whistle faults
re release
reduced speed cautiously considering cuttings curves crests visibility
must not exceed 15 through yards stations or near employees working on the line
high low beam over level crossing
72
headlight failure
one light failure no restrictions
day light- max 50 murl west richmond tunnel
darkness- 50 through stations / crossing loops 15 level crossing station yard
marker lights
frequent whistle
73
2 bogies is 80%
3-6 bogies 50%
74
window defect
external crack no problem
internal if the safety film isn’t compromised ok if it is you need a staff member
75
you can re-instate trip cock bypass key switch unlike
door loop and safety loop bypass
76
when the master key switch is turned on the trip will
lower but not set until coast/neutral
77
to reset the trip set the hand and use the turret switcg
78
water below the rail head not flowing?
15km/h
water over track or flowing do not proceed,
you may do 5km/h if less than 75ml and not moving after inspected by track maintenance representative
79
if the trip lowered light is illuminated after deactivating the cab
maybe the trip cable is broken
80
the secondary circuit consists of
safety loop
trip cock
81
driving on the secondary
MAD every 45 seconds, 10 second window
isolate CICERS even tho train will do it automatically too
82
main res normal operating pressure
850 to 1000
uncouple flashes when below operating range
83
if main res is below 600 because of air suspension leak
isolate air bags
84
siemans rescuing a siemans that is unbaked in one end, must isolate safety loop in lead
85
MR leak on 3 or 4
isolate end cocks and release SPB
bypass safety loop (isolate vicers cos ur on the secondary)
and shunt to nearest siding
86
compresasor faults
you will get illuminated tile with your low main res
train stable
isolate pressure switch
87

90
manual raise panto
stable
trip panto motor
open cabinet
remove handle
clockwise until resistance
activate cab
reset CB
raise pantos
panto test (if it fails isolate it in the lowered position)
91
isolate a panto with manual lowering
stable
trip panto motor
manually lower
activate cab
leave CB tripped out
