I don't think the document mentions this possibility- I only read through it
briefly BTW(please correct me if I'm wrong). By all accounts it does seem
that it is a rather strategic location.

The document was written by the Strategic Rail Authority, so long term
strategy will therefore be notable by it's absence! I must not be
specific, but let's just say the real strategic importance of North
Pole has fallen into the definition of the rail network "having to make
best use of present resources".
I'm personally fairly confident that North Pole will not become a
retail park or blocks of flats.
