The article assumes the completion of Crossrail. That's quite a bit of
extra capacity.

It is a lot of extra capacity. The majority of which will be made up, for
the first few years at least, of shifts from other rail routes - generally
from outside Greater London. Someone from Maidenhead who works at Bond
Street will be more likely to catch a Crossrail train than a Paddington
bound service (indeed, the Paddington bound services of today are more
likely to have a destination of Shenfield or Abbey Wood after Crossrail).
