This one was available in CAR right up until the building closed in 2013, and was still occasionally useful for lining up analogue circuits - like tielines around the building
Presumably its physical footprint existed simply as a board in CAR that wasn't taking up any otherwise useful space so to remove it would be unnecessary effort.
Central Apparatus Room. Lots of TV facilities have them - in TV Centre, it was in the centre wedge, third floor, and was subsumed into CCA (Central Communications Area). You'll probably find some old-school engineers who still answer the phone with 'CAR', just as some MCR2 engineers will still call it SCAR.
(SCAR was SPUR Central Apparatus Room, or Sub-Central Apparatus Room depending on who you asked - originally in Stage 5, and later near the end of the News Centre in Stage VI. Some people referred to the second one as SCAR6.)

There is still a role/operation called 'CAR', which does all the stuff they used to in TVC, except the bits actually involving TVC.
I assume they just couldn't think what else to call it. CCA still exists, but again it doesn't - its not central or an area
