Around noon today Live travel news on TfL's website was showing the
North London Line still with severe delays following the earlier track
problems; but at the same time the Live departure boards were showing
trains every 10 minutes at e.g. Highbury and Islington. And the person
for whom I was looking said there were trains with only the odd
cancellation. Is it normal for the 2 to be out of step please? And for
the departure boards to be the better guide?

IME it is normal for there to be a disparity during an advertised
disruption. I am not really convinced that the "severe delays" /
"Minor delays" methodology works terribly well on much of the
Overground network given the relatively lower frequencies than on much
of the tube.

I tend to put more weight on Live Departure Boards or Realtime Trains
because the data is from Network Rail's systems and more likely to be
accurate.

If the data comes from NR systems, what about the ELL?

What about it? It's part of National Rail so it shows up like any
other station.

I thought it was not part of /Network/ Rail though.

Of course it is.

No it's not. From New Cross Gate and New Cross to Dalston Junction, the
line is owned by TfL London Rail, and maintained under contract by
Carillion.

AIUI the line's signalling is done by Network Rail, but again under
contract to TfL.

I'd imagine that live running data for the ELL is passed via the same
systems (Network Rail signalling etc) as is the case for Network Rail
owned lines.

Thanks for that (and for the further background you and others have set
out). Seems we shall have to start checking Live Departure Boards etc
on a phone or tablet when out rather than relying on the Live travel
news displays at tube stations.
