Additionally the conductor rail has to be removed to allow the passenger
train to run; this is not a problem in itself but it does prevent future
demonstrations of automatic trains (something I'd love to see, but I don't
know if it's on anyone's agenda) if you remove too much of it.

I didn't know the line had been used for trials of automatic trains? How
would they get them up and down, given that the old depot can no longer be
used for surface access?

Here's how they took out some of the remaining trains in 2011:

And here's the crane: https://goo.gl/maps/EaqHVazHU3B2

The new trains went in that same way, much later.

This is an artist's impression of the refurbished depot, and it didn't
turn out quite like that. But I'm pretty sure I remember tracks in the
floor. The access shaft is at the far end of the lefthand section, which
like you said is set out as a museum, but had several bits of old
rolling stock which are probably not permanently blocking access.
Another site visit called for.
