You've lost me there. Which stairs exactly?

The stairs which formed a northern exit from the tube booking hall to
the open air, south of KX suburban. They could still be a useful
route for travellers St Pancras EM and TL (in good weather).

I would have expected an exit there through the new KX ticket concourse,
and via there to the tunnel which comes up opposite the "Circle" just
inside the StPancras extension. (But I haven't looked at any plans).
