And I dint think you could have the four rear carriages outside the

How long does did it take a train to cross that junction - 30 seconds at most?
With ATO timing would not be an issue.

On a related note , I notice that the tracks were left in situ before
crossrail came along and dug a huge hole just west of barbican so does this
mean the spur will be reused or was it just not economic to bother taking the
track up?

The latter, I think. Plenty of disused or singled lines still had the
disused tracks in situ many years later if the land wasn't needed for
something else.
