Misc. (Risk triggered commentary, VICERS, Faults and Incident Reporting, Arts Centre) Flashcards
What are the four distinct elements of Risk-Triggered Commentary?
- Risk recognition
- Rick identification
- Risk countermeasure
- Re-affirm risk (confirm it has been mitigated)
What are the mandatory applications for risk-triggered commentary? (2)
- All medium and normal speed warnings
- While performing the platform departure sequence
How can we avoid complacency and errors with risk-triggered commentary?
Don’t overuse it
What does VICERS stand for?
Vigilance Control and Event Recording System
What is the purpose of VICERS?
To ensure a train comes to a stop should a driver become incapacitated, and to maintain an event record should this occur
Where are the trip apparatuses located on each train?
Comeng, X’Trap and Siemens = On the number 1 axle in front of Wheel 8
HCMT = In front of Wheel 2
If the trip lever strikes the faceplate of the Train Stop, how are the emergency brakes then applied on each train?
Comeng = Brake pipe air pressure will dump, releasing emergency break
X’Trap, Siemens and HCMT = the Safety Loop opens to apply emergency brakes
What does the Vigilance Control System comprise of? (5)
- Task linking driver controls
- Vigilance Acknowledgement Button
- Vigilance Audible Buzzer
- Vigilance Fault Indicator
- Vigilance Activation Valve/Relay
What does the Event Recording System comprise of? (2)
- VM40 Event Recorder
- Roof-mounted GPS antenna
What are the tasks linked to driver controls that will reset the VICERS vigilance system? (3/5)
- Whistle
- Master controller
- Brake controller
(HCMT only
- Wiper washer
- Headlights)
How long does the Vigilance Acknowledgement Button flash/buzz for?
Flash 5 seconds, then flash and audible buzz 5 seconds
What happens if the vigilance button is not acknowledged after 10 seconds of warning?
Emergency brake application will occur
How long will the battery back-up system allow for the VICERS system to power after loss of overhead or 110v DC power?
What happens after this time?
5 minutes.
After 5 minutes, VICERS will shut down and emergency brakes will apply
How are emergency brakes applied on each train in case of VICERS time-out
Comeng = the VICERS activation valve (V.A.V) is opened, brake pipe pressure is lost and emergency brakes will automatically be applied
Siemens/X’Trap/HCMT = An electrical signal will be sent to open the safety loop and emergency brakes will automatically apply
When can VICERS data be downloaded and reviewed by management?
Whenever they want
What is the VICERS re-set procedure, in case of accidental activation? (5)
- Bring train to stand
- Wait 10 seconds after initial activation of emergency brake
- Push VICERS Acknowledgement Button
- Recharge brake pipe (Comeng) or reset safety loop (others)
- Report late running and cause to Metrol
What are the three positions for the VICERS key switch?
- OPERATE - for normal operation
- ISOLATE - in case of defect
- TEST - to initiate drivers test
What to do if the VICERS fault light illuminates?
What will happen to data recording in this instance?
VICERS must be set to isolate in case of fault light to prevent VICERS button from activating
Data will still be recorded,
