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,
Unless otherwise authorised, how must the driver of an EMU arrange the Leading and other Trip Valves?
Leading Trip Valve must be “cut in” (lowered)
All other Trip Valves must be “cut out”
What does FMP stand for?
Fault Management Procedure
What are the four elements that comprise the Fault Management Procedure (FMP)
- Train Malfunction Message Book
- Fault Warning Notice
- Fault Warning Notice Reduce Speed Stickers
- Serviceable Criteria Book (electronic, in Paperlite)
What are the four main types of fault that drivers will encounter?
- Critical fault
- Serious fault
- Maintenance fault
- Remarshalled fault
What is a critical fault and what is the protocol if one is discovered?
Critical fault = integrity/safety equipment not functioning correctly.
Train must be removed from service ASAP and must not dock into revenue services. If safe, it may be run to a maintenance facility in non-revenue service.
What is a serious fault?
A fault on train where integrity/safety is not affected.
What happens if train encounters serious fault?
Train may remain in revenue service, but will be removed as soon as reasonably practical
When does a serious fault expire?
When the train shunts and stables. It must not be run in revenue until the fault has been rectified or remarshalled
What are the three sub-categories of a Serious Fault?
- Priority
- Return Run
- End Run
What happens to a train flagged with a Serious Priority fault?
It will be removed from service?
What happens with a Serious Fault: Return Run and when will this category be given?
It is given if the fault pertains to the leading cab.
It can be run in revenue to its current destination. It can then only be driven from the opposite cab as far as the Metro system allows.
How many days can a train with a Maintenance Fault be driven in revenue service for?
up to 90
When might a Serious: End Run fault be given and what are its limitations?
When the fault pertains to the trailing cab.
It may only be driven from leading (non-defective) cab as far as Metro network allows
What happens if a fault is rectified in running? Who is monitoring these faults?
Driver to write RIR on TMM notice (courseware says to remove, David says not to remove. Idk tbh)
Fault monitored by Fleet Maintenance Coordinators
What are the two colours of paper in a Train Malfunction Message?
What happens with each colour?
Pink and green
Pink to be placed in the TMM clip of driver’s cab of affected carriage or unit. Green to be kept by driver.
What details must be given when sending a Train Malfunction Message? (5)
- TDN
- Train time, destination, origin
- Affected carriage number
- Details of defective equipment
- Equipment isolated (if applicable)
When must a driver report faults?
When it is safe to do so
Can a TMM be used to record multiple faults on the same carriage?
No, each fault needs its own form
What information does the Train Controller give the driver to complete the TMM form?
- Fault category
- Fault reference number
When are Fault Warning Notices to be completed?
When isolated equipment affects the operation of vital safety equipment on train.
Where are Fault Warning Notices placed?
In both cab ends, with stickers on each speedometer (if applicable).
