Differences between a 150/1 & 150/2?
• 150/2 has 2x alternators
• no DVD in 150/1, DVD in 150/2
•AWS Full Isolation is Handle type where middle window is on 150/1 - AWS Full Isolation is on secondman side and is a flap like EBS
• 150/1 is crew door is a slam door - 150/2 crew door is air controlled
• 150/1 no gangway door - 150/2 gangway door
• LCCB Trips on 150/1 in the front means engine shuts down, rear engine turns to idle means coasting to stop somewhere. no brake release if TW4 breaks
LCCB Trips on 150/2 if front engine shuts down will still take power from rear, can get brakes still.
Emergency Egress switches on alternate saloon doors on 150/1
emergency egress on every saloon door on 150/2

72
AFTER THE FIRE, what must you do after a fire is dealt with?
why would you do these things?
- silence bells and turn off hazard light by operating the FIS (fire isolation switch)
- extinguish engine stop light by operating Engine Start Isolation Switch (ESIS) this is located on the local control panel on non drivers side
- when authority given move all passengers out of affected vehicle and place a competent person in there
fire system now inoperative in that vehicle
you would do the above so that you are alerted to any further possible problems
73

all non essential items
- GSMR
- Door supply
- interior lights
- heaters
74
what does the starter batteries control?
All essential items

- Local Control
- Door Control
- Brake
- AWS/TPWS
- Train Control
- P.A
- Wheel slip
- remote supply
75
when would you and what happens if you need to operate TIS (Traction Interlock Switch)?
if you have brake release but are unable to take power you may need to TIS. Once operated driver must manually check all doors are closed and locked, buzzer will now be inactive (buzzer runs thru TIS) at end of journey TIS should go back to normal position.
76
what to do if ebs needs raising in leading cab or other than?
when EBS is activated, if fault is at home (driving can) move away, if fault is away (other than leading cab) stay home.
77
if guard has to dispatch without using bell buzzers codes due to TIS on how does he do it?
using a whistle and green flag.
78
how many times can you reset a circuit breaker that’s tripped on own authority?
3 times unless earthing mcb then only once
79
what happens if the fire system trips?
how to amend after 3 resets?
lose fire integrity (light go off), engine & aux heater will shut down. engine stop light will illuminate.
to fix - isolate engine to remove stop light
80
what happens if TCA trips?
loss of tca in local vehicle (rear tca not affected)
transmission train and unit lights lit up in affected unit in other units will just show transmission train light, hazard warning light illuminates on affected vehicles
81
earthing mcb trips what happens?
no fault indication when tripped (only reset mcb once)
82
door control mcb trips what do you do?
loss of door control panel
have to operate doors in other vehicle where not defective
83
brake control cb trips what do you do?
When tripped in either energised or de-energised cab you will have a full service brake application due to a brake in the brake safety loop.
If tripped in rear cab raise EBS in energised cab to proceed. If tripped in energised cab either move away to rear cab for WDM or get assistance at the leading end. Both scenarios require EBS to be raised in energised cab to proceed.
84
what happens when AWS/TPWS trips?
how to rectify after 3 resets
lose AWS/TPWS causing break in TW4 making a a full brake application
must isolate AWS/Tpws continue line speed with competent driver or 60 without and 40 in poor vis
85
what happens if PA CB trips?
lose use of cab phone and PA
86
remote supply cb trips what happens ?
lose back up of batteries suppling power feed to mcb’s
87
what are the wet faults if an engine turns but won’t start?
low fuel
low coolant
low oil
88
what are the dry faults for if an engine won’t start ?
faulty starter motor
faulty start button
ESIS operated
starter battery dead
89
what happens if the fire system cb trips?
loss of fire integrity - means engine & aux heater will shut down (engine stop light will illuminate)
to remove stop light, isolate engine
