It might be obvious but not to me. What is the
advantage of having all the units the same way
round during the closure of the loop?

I could understand if the loop was going to
permanently closed, so that route maps could
also be displayed 'in the direction of travel',
but not while it will reopen as a loop.

It would still be possible to introduce handed in-car line guides with half
the cars the wrong way around, so long as they stayed the wrong way round
for the duration of the closure.
