Sorry to bother you busy folk

I'm travelling from Woolwich Arsenal to KX on Monday morning, [1100 to
Newcastle].

Because I have difficulty walking (stick, won't bore you with the
tedious and painful history) and will have overnight bag, laptop etc,
prefer step free.

At London Bridge, I can easily change from the through service [to
Charing X or Cannon St] to FCC northbound.

But where / how do I emerge from the new T/link platforms at St P?

Rummaged through all the usual websites - can find all LU i/change
info, but not St P domestic

All info / pointers etc grat rec

TIA
