I hope most of these will be by the small fixed crane over the shaft,
and not a road crane.

I've only once seen that crane used; to lift out the bars with wheels
fixed to the ends which guided the new cars down the shaft. I see the
same things were fixed to the ends of the cars as they were lifted out.
I assume that it is used from time to time for lifting smallish items
into/out of the depot.

Where is the entrance for staff; other than going in by train?
