what is affected on a motor car with no Main Res

A

trip
whistle
pantos down so no
MA so half saloon lighting half air con
air bags and saloon doors

if it’s the lead max 15km/h EMY brake only need a CE otherwise disabled

35
Q

why do we trip the EP in a main res rupture

A

to have maximum brake capacity

36
Q

what do you do to a trailing motor that has a MR rupture

A

end cocks
manually release SPB (don’t need to isolate as there’s no MR going to it)
lower and isolate panto motors out
trip out the compressor governor?
yellow TECHAV
move passengers and lock communication doors

37
Q

what do you need to do in the LEAD cab of a MR rupture

A

isolate VICERS
isolate door loop bypass
trip EP
open bvics set trip
release SPB
half track speed to a max of 30km with air bags out

turn the end cocks
move the passengers and lock communication doors

39
Q

if there a main res tank rupture

A

turn the main res delivery end cocks
turn the comp contacter off
isolate the compressor governor circuit breaker

40
Q

automatic drain valve broken off

A

blank the pipe from the bogie to the min res or it will leak the BC if your using EP brake

41
Q

if the flexible hose is broken between cars

A

close the end cocks

42
Q

how
might you know you have defective air suspension

A

complaints
rough riding
observed off levelling in a train prep

43
Q

how many air suspension IC. per bogie

A

1

44
Q

defective or low control res

A

turn the yellow techav the trip will lower and no power in that motor but the others will power because line breakers can’t close

if you have a problem before control res in cock it’s a MR issue if it’s after control res out your trip is ok but you can close the line breaker contacters

MOTORS OUT if the control res is ruptured turn control res in

45
Q

to isolate the trip lever if control res air is leaking out

A

turn trip gear IC in van area
(to save BP)
whenever control res is isolated you need to turn the yellow because it can’t be held up

46
Q

whistle

A

hit the lever
turn the cock open close the same way

47
Q

APA alternative proceed authority

A

CBTC communication based train control

48
Q

route indicators DNG to EPH

A

plat 3 get the up (normal)
2 get the left (diverge)
can’t get FROM 1 to EPH
can get TO 1 from EPH

49
Q

what. could be the cause of rapid BP reduction

A

trip
VAV
pilot valve dropped
if the noise isn’t in the lead
back tripping
VAV in trailing if it has yellow techav

50
Q

TECHAV

A

trip missing or failing to reset
emergency application valve not resetting
Control governor not closing
hand and foot not able to reset
anti- neutralisation device activating above 8km/h
VICERS activation valve failing to reset after being isolated with the key

51
Q

FEEC

A

foot pilot valve
emergency pilot valve
emergency control governor
control governor bypass push button

52
Q

rupture in BP to tripple valve

A

isolate BP to tripple valve
isolalate MR to seven step manually release brake on bogies on that car run on the EP
speed is 10 less until 60 for 80% bogies

53
Q

possible reasons for deficient EP

A

interruption of electrical wiring ABCD wires
defective brake unit on any car individually
defective brake controller or relay unit whole train
mechanical brake down of rigging
could also be isolated bogies 1 if BC gauge shows 0
run on the air

54
Q

skidding wheels indications

A

while powering and braking:
steady wheel slip light
flashing line switch and local
this car in affected car

can tell by retardation, smoke, maybe sound

55
Q

skidding wheels 5km/ro clear a section

A

following trains 15/h under FTPC instruction until track is inspected

56
Q

water over under the railhead not flowing

A

5km/hr -once authorised!
under the rail head not flowing 15

57
Q

the local fault light is shared with traction (line switch) and rheo (rheo)

A

sometimes it remains illuminated even after equipment is isolated, the driver can identify a new fault by continuous illumination of the line switch fault light while powering or rheo fault light while braking

58
Q

what could cause traction faults

A

control res faults
pneumatic leaks
traction overloads tripping
1500v DC failure
circuit breaker failure

59
Q

control res fault

A

line breakers can’t close get a line switch fault light
also trip won’t raise

60
Q

1500vDC fault indication

A

also a line switch light, could mean there’s a panto not making contact with the over head, if the traction overload reset doesn’t fix it this indicates a more serious fault

61
Q

traction overload reset button

A

will illuminate the line switch light, you can attempt to rectify by going to coast and off and pressing the button, if it doesn’t work you gotta put motors out, isolate rheo

62
Q

if the traction overload reset button is causing the control circuit breaker to trip

A

you have to find which cab the fault is with this car light and isolate the motors there

63
Q

how many motors do you need on a consistent to remain in service?

A

50%
one set of motors out is 25%

64
Q

isolating traction faults with motors out

A

go to off remove key and use it to place motors to all out
press the traction overload reset button and try again for power/control gov/hand pilot functionality test.
if the fault lights extinguish yay, if one remains (maybe local) book it

65
Q

panto interlock auxiliary isolate switch

A

if this or the main switch is turned you should have a yellow sticker on the bulkhead wall from fleet maintainers

(if your doing traction faults and it’s not local you can still try traction overload as it’s a train lined button)

66
Q

what do you lose when you isolate a panto

A

half air con half saloon lights half head lights,
local rheo out and half cab lighting and heating
the other half is run by the 415 from the leading centre motor panto

67
Q

how do younger which MA is out on the unit

A

look for the air con fault light above the bulk head door in the drivers compartment, which ever is illuminated is the one that’s out

68
Q

illumination of MA fault light

A

1500v problem
MAC air leak
loss of MR
van area IC turned
panto down
over speed - can only be identified by observing the over speed trip on the MA
GEC westcode- underneath use switch stick, will stop running no sound
Mitsubishi knorr- on the side, will keep running but no output

69
Q

DC supply circuit breaker

A

a short circuit in the 110 DC supply cable will cause ALL CB to trip,
try and reset the lead, if it can’t need RTA and try and reset at least 1 - if you can’t get one set your disabled
will cause MAs to overspeed make sure you reset the CB before you reset the MAs

70
Q

what else should you try for an MA fault light

A

press the aux start button

71
Q

air con fault lights

A

flashing 2 in one car, steady one in one car
to tell which one you have the saloon area lights on both ends of a trailer car
motor car it’s in the drivers cab above the bulkhead wall

72
Q

control circuit

A

master controller closed - nothing you can do CE or rescue
master controller open- try the different notches, if it trips in shunt go motors out and see, if that doesn’t work PA TEC leading centre motor and try motors out there, if it doesn’t work divide the train and reattach non electrically DLbypass detrain first opportunity etc
master reverser- if it’s F,N or R and brake handle is applied, isolate local rheo and see, if not reset the rheo and trip the EP, reset control CB if it stays set drive on the air, if not you gotta drive from another cab / get rescued
remote panto raise- raise each manually
remote panto lower- reset CB, isolate panto EP, press trainloned panto lower, if it will trips go look for the one that won’t trip it when lowered.
electric brake demand circuit
traction overload reset- find the car with this car fault light and isolate the motors
(also supplies power to the speedo and control governor)

73
Q

if the EP CB is tripped

A

the EP and rheo brake does not operate on the train

74
Q

compressor gov sync circuit breaker

A

you could use if you isolated the main res in that car so it doesn’t interfere with the other comp governors or you could just de energise the comp gov CB? this will remove the function of train lined SPB in that car though

75
Q

comp contractor switch vs compressor governor isolating cock

A

turns compressor off
makes compressor run continuously because governor isnt governing

76
Q

when you lose one MA

A

half saloon lighting (generally a 1 on 1 off pattern)
half air con, motor car with the MA not working will have air con #1 not working
half can lighting and cab heating
local rheo brake where the MA has failed will be inoperative due to a cooling fan that is powered by the MA

77
Q

will the MA and air con fault lights he extinguished by isolating equipment?

A

no

78
Q

if you turn the SPB IC

A

the status lights will come off but the brake will remain applied until it is manually released

79
Q

make sure the park brake is on and the tap is closed

A

to ensure that no main res air is being supplied to the SPB while you are trying to manually release it
