Q

the bogie isolating cock is self venting. that means that when isolated the breaks will release on that bogies

A

it may be necessary to isolate the SPB it may be necessary to isolate the SPB and release it as well if the break block does not clear the wheel

A

make a PA to clear doorways
ask passengers to make a PEI if they see an obstruction
view mirrors
reduce speed

25
if you come to a stop while the the door light is flashing when will you get traction
once it’s stead or bypassed
26
once the door loop is bypassed can you turn it back?
no?
27
how many doors can you isolate to remain in service
one per side per car
28
can a train go into service if a can door cannot be secured
no
29
if the safety film is in tact inside and the window is cracked can you dock up?
yep
30
if the safety film is compromised can you be in service?
only if protected by a competent employee
31
how can you check if the window has a film
use your fingernail to check 5mm from the edge of the window
32
what must you take when protecting a train and how far do you go?
radio keys DRA red flag/ torch
33
drivers are not to fit transition couplers
true
34
powering and braking from behind
15km/h
35
powering and braking from the front
reduced speed cautiously
36
powering from the back and braking in the front
40
37
if comms fail how can you get a proceed
green flag all right hand signal bells whistle code
38
the trip of the leading can must be lowered unless defective
unless you are driving from the rear then you can drive on the secondary with it raised because the stop arm will be raised by the time you get to it
39
1500v dc panto faults
damaged carbon strips damaged panto heads damaged panto arms main res air leaks electrical defects end of overhead dissaranged wires
40
how do you isolate pantos electrically
with the toggle switch
41
if there are burn marks or metal on metal on the panto
it must be lowered isolated and booked
42
can you use a crank handle to lower a panto?
yes but not raise it
43
ROBBDS TEST procedure INITIAL CHECKS
trip- set and lowered switches- normal position CBs normal, door close button steady blue gauges- main res, brake pipe, control res cocks- BIVICS red EC
44
ROBBDS TEST procedure after initial checks 110v dc supply
check supply light doors open close LP flag is lowered ep works bell operates
45
ROBBDS TEST
Reverser traction overload brake pipe reduction control governor bypass door loop bypass second master controller
46
what lights will you get for rheo faults
rheo brake light local
47
what lights will you get for traction faults
local line switch
48
what does the control res do and where does it operate
490 keeps the trip in position operates equipment in the main equipment and line breaker case
49
what does it mean if the line switch light is on?
air can’t get to the line breaker case and close the circuits so there is no traction for that car only
50
you can try and fix traction and rheo faults by using the
traction overload button, if it doesn’t work switch the motors out and book it, that car won’t have motors
51
what else will fleet maintainers do if they tune the main switch
put an equipment sticker on the bulkhead (auxiliary isolate is for MA and air compressors)
52
loss of over head with comms
the substation will try and reset twice; TC will stop all trains and ask to lower pantos, substation will try and reset, if successful TC will contact each 1 by 1 to raise one panto and one MA at a time and determine which train and which panto has the problem. once isolated each train will be set off one minute apart to avoid drawing too much power at once. drive in series until advised by TC.
53
loss of overhead no comms
don’t assume it’s loss of overhead, take initiative. check trips switches gauges and cocks. check DC supply. check AC supply, headlights saloon lights) try to reset MA on the underframe, repeat in leading centre. if still no compressors assume it’s loss of overhead TOTS
54
if you lose overhead and there’s no comms and then it comes back
you can drive off if your an up train after 30 seconds and if your a down 60 seconds drive in series
55
how long do you have on the battery in a comeng
2 hours
56
when will the LSM activate?
after 2 continuous seconds with less than 95vdc from overhead
57
what are the components of the LSM
the time delay relay which activates 4 mins after the BIVICS closes the speed threshold of 8kms
58
what happens above the speed threshold when loss of overhead
the pantos will stay up EP trips- LP flag up, air brake (lead) MAC stays on in the lead, off in the trailing motors MA’s shuts off
59
what happens when loss of overhead under the threshold
lead panto stays up trailing pantos will lower MAC stays on in the lead, off in trailing MA’s turn off EP will trip, LP flag, air brake
60
the VICERS application valve will activate after 5 minute of loss of overhead
leave brake handle in emergency so it doesn’t waste main res air on trying to charge the VICERS
61
what will be the effect of a weak substation output
reduced reactive effor reduced rheo performance loss of one or more MAs loss of one or more air cons
62
what jolene once a weak substation has been identified
TC will ask one train at a time in that area to raise all the pantos and start only lead MA. drive in series until next substation area
63
when does the wheel slip light illuminate
when there is more than 15km/h difference between axles
64
where are the frequency generators and wheel slide cables?
1357
65
what is protected by the control circuit breaker
control circuit reverser master controller control governor rheo brake panto raise and lower traction overload reset
66
auxiliary control circuit breaker protects
Bell auxiliary start doors release and close saloon lights on and off couple and uncouple air con #1 control local rheo brake schafenberg coupler self centre
67
CONTROL CB train line panto raise
manually raise panto individually by EP button, local panto raise button
68
CONTROL CB train line panto lower
isolate panto electrically, (toggle switch) individually. once the fault is found lower and isolate that panto locally
69
CONTROL CB traction overload reset button
locate this car light, isolate motors all out
70
CONTROL CB master controller closed, reverser off brake in release no panto buttons or traction overload reset pressed
there’s a short circuit in the wire between the control cb and master controller. can’t drive from there
71
CONTROL CB master controller is closed, reverser is off brake is APPLIED
1 defective rheo- isolate local rheo via toggle 2 short circuit in rheo demand(train lined cable) - isolate trainline cable by tripping EP CB 3 short circuit between CB and master controller- drive from another cab
72
CONTROL CB master controller is open
try lower notches if trips in 4, try 123 if in 3. 12 if in 2. 1
73
CONTROL CB master controller is open notch 1 shunt trips
defective traction control equipment (traction motor) or control circuit cable is defective 1 isolate lead car motors 2 isolate leading centr car motors 3 divide the 6 cars and recouple non-electrically 4 if lead CB stays on issue is another unit drive from lead unit trip EP CB door loop bypass de train 5 if lead CB trips can’t drive from there, trip EP and door loop and de train
