Question 30

What happens if you isolate the MRPIC?

Answer 30

- splits air making bottom half of the system from the distribution side - assuming MRPCC aren't isolated, other trains will still feed the CABS - only necessary if a leak has developed on the production side

Question 31

What happens if you isolate the ASRIC + ASICs

Answer 31

Once you operate the 3 surge tank drain cocks then you will have isolated the air suspension system

Question 32

What happens if you isolate the CGIC?

Answer 32

air will build up within the system and main air will be expelled through the safety valve at 8.3 bar

Question 33

What happens if you isolate the BSRIC?

Answer 33

- air will no longer be supplied to the brake supply reservoir - though this may not be immediately apparent, this will eventually result in losing the brakes

Question 34

What happens if you isolate the MRPFIC?

Answer 34

Air will no longer be able to supply the CABS if supply is being relied upon from other coaches, ie, production side is already isolated

Question 35

What happens if you isolate the BCIC?

Answer 35

Brakes are no longer working on that coach
