It is interesting that they are talking about resignalling the NLL, yet
the signals on the ELLX are regular national rail signals. Would that line
already have to be resignalled by 2012, considering that it would still be
relatively new?

The stuff that you can see (ie LED signal heads) on the ELL is the same as
the stuff being installed every where else on NR, why would it be changed?
Resignalling doesn't necessarily mean a step change in technology, such as
we are seeing on the LU lines. Also, the ELL is a separate signalling area,
controlled from New Cross Gate SC. It is highly likely that the southern
pair of tracks from Dalston Jn to Highbury will be part of the ELL for
signalling purposes, with the transfer crossover being the signalled route
between the two separate 'systems'.

AIUI the NLL is only being resignalled for shorter headways, it will still
be conventional NR signalling, but will all be controlled from Upminster,
rather than a number of local signalboxes.

Thinking about it, the whole question about what's happening on the NLL may
be to do with the phased nature of the four tracking around Camden Town.
Perhaps the final transfer to Upminster will only be done when the second
phase of the work is complete, thinking back to discussions about the
reducton of the scope because of the bridge repairs needed at Camden Town
itself?

What's that about Upminster?

Upminster IECC (that's the NR signal centre there) eventually gets full
signalling control of the NLL...

Upminster is where the new signaling will be controlled from.

On trains towards Dalston, anyway. Trains heading the other way will
obviously be controlled from Downminster.

Cool.

BTW, anybody who owns an iPhone and has the National Rail app will find
that its latest update contains Dalston Junction, Haggerston, Hoxton and
Shoreditch High Street.

No schedule information is yet available from any of those stations,
unfortunately.

See this gun Mr Anderson? Well I'm about to kill you with it for your
appalling taste in jokes.

You're dead (or bloody well deserve to be!) -- Downminster. I ask you.
;-)

Dunno. Isn't it in the same league as extreme cases of madness - at least
Dagenham if not the full Upminster. Well beyond Barking, anyway.
