Q

What are the safety-critical faults that appear on the Fault Warning Notice book? (5)

(side note, it’s dumb we highlight/memorise this because in the field we would just look at the literal book)

A
  • Bogies Isolated
  • Airbag deflated
  • Lateral sway fault
  • Red EC/Yellow TECHAV isolated on a lead/trail motor
  • Doors isolated

(BALRD - as in, let me sing you the BALRD of Safety-Critical Faults that Appear on the FWN book)

Q

If a train is skidded clear of an area, infrastructure personnel will attend and examine the track. What guidelines will the personnel put in place?

A

All following trains must be stopped, or travel at reduced speed, until the track is deemed to be safe.

(This questions is shonky but I couldn’t think of a better rewording)

What percentage of bogies must be available for a train to remain in service?

A

50% of greater. If lower than 50% train is declared disabled.

16
Q

If number of isolated bogies equates to having between 50% to 80% of a train’s breaking power available, what speed restrictions apply?

A

Train must not exceed Extreme Caution

17
Q

What must a driver do if the FDCL continually flashes between platforms? (5)

A
  • Make PA requesting passengers stand clear of doors
  • View mirrors for passenger safety
  • Reduce speed
  • Advice train controller of situation
  • Stop train at next platform (regardless of conditions)
18
Q

What service restrictions apply if a train’s window is externally cracked?

A

Train may remain in service

19
Q

When a train has been combined in case of a fault, what speed restrictions apply if the train is powered and braked from the leading motor?

A

Reduced speed

20
Q

When a train has been combined in case of a fault, what speed restrictions apply if the train is powered from leading cab but braked from a trailing cab?

A

15km/h maximum

21
Q

When a train has been combined in case of a fault, what speed restrictions apply if the train is braked from leading cab but powered from a trailing cab?

A
