I heard tonight at a meeting in Acton between local residents and
Network Rail/Tfl/LOROL representatives that Ian Brown (MD, London Rail,
TfL) had announced in his report to the Mayor at the TfL Board meeting
last week that the North London Line resignalling was to be postponed
until after the Olympics. This was reported by someone in the audience
tonight, and was clearly a complete bombshell to the people on the
platform. They had previously claimed that the resignalling was the
main reason for the continuing lack of Sunday services on the NLL.

I've now found the relevant part of the webcast of the TfL Board meeting
and have transcribed it (see below).

I don't think Ian Brown has been "very clear", despite what he claimed.
He makes it sound as if TfL are doing the "physical stuff", and then
Network Rail will do the new signalling later. But surely all the
4-tracking work, new crossovers etc. will be done by Network Rail or
their contractors? What about the signalling for the new or changed
track? Will that be cobbled together à la Jubilee Line and then
replaced post 2012 or what?

Network Rail's agreement to this change of plan would be crucial, yet he
makes no mention of that. Extraordinary.

And can the 8tph timetable for 2012 be supported reliably by the
existing signalling ?

Can anyone throw any light on this "decision"?

Transcript of Ian Brown's statement:
"Bit of a dilemma on the North London Line infrastructure. I just want
to be very clear on what we've done. This is a Network Rail 4-tracking
scheme for our Overground, also for freight trains and for all the other
stuff that runs on that line. Big scheme, £300+ million, and we've got
all sorts of problems with signalling design with Network Rail. It's a
general problem with Network Rail, as people know round the table, and
the dilemma for me is to have that service running, and to make sure
they guarantee to have the service well in time for the Olympics, of 8
trains an hour. What we're going ahead with [is] the blockade in
February - 3 months' blockade from Gospel Oak to Stratford. We're going
to do all the physical stuff, but we're going to keep the old signalling
going, so we've actually done the work, then Network Rail have got to
come back and do the signalling later. So we have actually secured our
frequency, we've secured the Olympic frequency, we've not secured the
corporate railway, and there's also some issues about freight trains, so
the scheme's got to be done, but we've secured our bit by that decision,
which was quite a difficult one."
