Are they running a special timetable prior to the closure in order
to get all the trains the same way around during the closure, or is
there no such thing as a 1973 stock being "the wrong way around"?

Unfortunately, there is. When the stock was built, there was no such
thing as the T4 loop, and all the stock was built handed.

Only the double ended cabs are handed.



Fortunately the Aldwych branch still existed at the time, leading to a
quantity of double-cab units being built.

They were primarily built to provided flexibility when a single ended cab
need to be withdrawn from service.
