The observation that triggered the question was seeing, on one of the
maps on board a tube train, a station showing an interchange opportunity
with London Overground, but *not* showing the National Rail symbol
against the station name. *Which would seem to imply not.

Yes. And no. And it depends on what you mean by "National Rail
network" anyway.

The current LO network - NLL, WLL and DC line - is all part of the
National Rail network - for example NR ticketing applies.

When the ELL reopens, then the section from Dalston down to New Cross
and NXG will not be part of the National Rail network (it's also not
owned by Network Rail), and the NR double-arrow symbol won't appear on
station totem signs along this stretch. How through NR ticketing will
work on this line is yet to be made clear.

TfL seem to regard LO as a kind of metro network - as the LO name
suggests, sort of an overground equivalent to the Underground. And
ultimately TfL are free to show interchanges on in-carriage Tube
diagrams however they please.

The travelling punter isn't going to care one way or another - what
they will know is that it's clear that TfL are responsible for LO. The
memorandum of understanding between DfT and TfL with regards to the
London Rail Concession agreements makes pretty clear that both parties
regard this as an open ended arrangement, i.e. TfL would be
responsible for these services for the foreseeable future.
