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?

If there's no surface access, how did they get the tour-trains in there?

The surface access is in the former depot area, now turned into the tourist
train base and station. That's probably partly why it's so shallow, just
below the surface. The running line is deeper, a proper tube railway.

That doesn't answer the question: "how did they get the tour-trains in
there?"
