Interrogate TMS for location of dragging brakes,
Speak to signaller and maintenance,
Go to relevant pneumatic cupboard at number 2 end of concerned vehicle.
Isolate BCIC and allow to fully self-vent then reinstate it.
Go back and check TMS to see if fault has been rectified.
Inform signaller and maintenance of your findings.
If the fault is still there then a brake isolation will be required for that vehicle.
Rule book conditions will apply
If it becomes necessary to isolate the parking brake, how is this done on a 222
Isolate BCIC and allow to self-vent.
Isolate PBIC and allow to self-vent. Competent person then to pull parking brake release pull rings.
Do not reinstate any of BCIC/PBIC as fault will return
The TMS Screen on a 222 indicates HOT axle box, explain what your actions are
Ensure train secure and safe to alight i.e. lines blocked etc,
Use temple stick on inside of wheel
Check other wheels as per rule book and complete a wheel rotation test.
Isolate detection cock, to remove fault and stop the air loss.
Contact maintenance control.
How do the warnings differ between a fire detected on the underframe of a vehicle (engine zone) and a fire in the body (non-engine zone) on a 222
The red Level 3 fault lamp marked fire illuminates.
Flashes to indicate a fire inside the body (non-engine zone)
Steady to indicate an underframe (engine zone) fire
Fire bell sounds continually in both cases.
If the fire alarm sounds there are four areas that could cause the activation , where are they on a 222
Manual Call Points.
Galley/Retail.
Engine
Toilets.
If the automatic fire system fails on the diesel engine, what action can you take on a 222
Shut down the engine if not done automatically
Activate the fixed fire fighting system manually by operation of the external cord on the affected vehicle.
Can use the on board portable fire extinguisher.
The on board portable extinguishers are of the AFFF or Co2 type, but you must not put yourself at danger.
What other class of train may the 222 be coupled to electrically
222 only
How do you couple to another 222 in normal operation
Stop 6 ft from train and check that there is no N/M signs, the train is in normal running state, doors are closed, no master key in, electrical box cover closed.
Stop 2ft, get down and check the alignment of the couplers.
Select forward and couple at no more than 2 mph, once coupled apply the brake and select neutral.
Select reverse and complete a pull test.
Select neutral and then press the couple button for at least 5 seconds.
Check the TMS screen that extra vehicles are shown.
Press the lamp test button for 10 seconds or until the fire alarm is heard, to prove continuity.
Select state on the TMS and check the coupler state, this should show (completely coupled)
Leave PBH in high position, set DRA.
Tum external lights off in both cabs.
Remove master key and secure cab
You are sent to assist a failed 221, how do you set up the 222 and 221 into recovery mode
and move the train off the main line
Failed 221 unit, must have doors closed and no master key in, check all Auxiliary controls, isolating cock (ACIC) in the normal position.
Close the MRPic (yellow cock located front of train)

In a 222 on the fault indicators panel in the cab, state what would cause each
light to illuminate
SAFETY SYSTEM ISOLATED FAULT: This acts as a reminder to the driver that a safety system on the train has been isolated.
Driver will be able to see which system is isolated by looking at the safety isolation switch panel
- 2&3 SPARE
- BRAKE FAULT: This indicates that a dragging brake has been detected or that a parking brake is applied.
- BOGIE FAULT: This indicates one of three things;
a hot axle box has been detected
air suspension is deflated
cardan shaft fault.
- WHEEL SLIP PROTECTION. This indicates that the braking system is controlling wheel slide on braking (on the leading vehicle only).
No indication is given on acceleration.
- TRAIN DATA RECORDER FAULT: This indicates that the train data recorder in that cab has failed
- TMS LEVEL 3 FAULT: This is provided for consistency of driver interface between level three faults raised by train wires and level three faults raised by the TMS.
It illuminates when the TMS detects a level three fault. It also allows quick silencing of the level three warning
buzzer.
- FIRE: Flashes to indicate fire inside body (non engine zone),
Steady to indicate an underframe (engine zone) fire. (The fire bell sounds continuously in both cases).
- TCA FAULT: This indicates that one of the TCA systems on the train has failed
Explain or Draw the Drive line on a 222
Engine - alternator feeding into the propulsion case.
Propulsion case feeds the Aux converter which provides the different voltage outputs 24v DC, 110v DC, 230v AC and 400v AC
Propulsion case also feeds the traction motors which use a roof mounted resister
How do you enter a 222 from the ground level and platform level
