So there might be a case for diverting HEx (in tunnel, not wandering
all round Cricklewood) to St Pancras.

Would this be a new station at St Pancras, or maybe sharing the Kent
domestic platforms, which might be over-specified. On the other hand, if
Thameslink2012 does in fact include through-running from the GN services
on the ECML, there will greater spare capacity at KX.

I envisage an underground terminus, possibly double ended, with one entrance
from the concourse at St Pancras (near the access to the Thameslink
platforms, and another with an entrance from Euston (may need a travelator).

What would it be "underneath", there's a lot of existing stuff under StP
and KX, and I'm not sure you'd be able to locate anything under the
British Library.
