later.

TfL has requested that the ELLX project team look at (the
costs/benefits of?) connecting the extension at its northern extremity
to the NLL proper - indeed the RUS as published last week refers to
this. In addition, I read somewhere today (can't mind where - sorry)
that the new rolling stock is to be maintained at a new depot in the
New Cross Gate area (dunno where though) which would suggest that a
connection will be necessary to facilitate stock transfer.

In Phase 1, there will be a connection at New Cross Gate (for the West
Croydon - Dalston Junction and Crystal Palace - Dalston Junction
services), so there will be no need for a connection at the north end
just to transfer stock. (However, ISTM that it would make the service
a lot more useful at relatively little cost if through running to the
NLL was done as part of Phase 1.)

Aha - today it looks like that part has been moved up to Phase 1. See my
post on "London Overground".

The plans are for the current (self-contained) WLL service to be
replaced with through running from the NLL (Stratford to Clapham
Junction), so it wouldn't be possible to use a different type of stock
just for the WLL. The Euston to Watford service will be axed
completely, but this only uses something like 4 of the 23 313 units.

It seems apparent to me from the figures that the proposed doubling of
the frequency on the WLL and NLL (and the reopening of the Queens Park
- Camden Road route) will be achieved simply by running the 376s in
addition to the 313s, rather than the 376s replacing the 313s. The
options in the contract would then allow the 313s to be replaced at a
later date with a subsequent build of 376s.

Yehbutnobut.

As far as I can tell (certainly according to NR's RUS -
http://tinyurl.com/hbkhq ), the medium-term plan to take effect by 2009
when these trains are introduced is for:

Stratford - Richmond x 4
Stratford - QP x 2
Barking - Clapham x 2
Barking - Gospel Oak x 2
Watford - Croydon (via Clapham) x 1
Shepherds Bush - Croydon (via Clapham) x 1

This is the same frequency as at present on Stratford to Richmond.
(snip)

The information coming out of various transport orifices regarding the
future "Orbirail" service patterns is a bit of a mess. The most recent
TfL plan prior to the publication of NR's RUS was relatively simple. THe
first phase was:

4tph Stratford to Richmond
4tph CJ to Stratford
2tph Gospel Oak to Barking.

However, NR's RUS now says that TfL's proposal (service variant SLC2 for
implementation in Jan 2011) is the rather bewildering:

4tph Stratford to Richmond
2tph Gospel Oak to Barking
2tph CJ to Willesden Jcn
2tph CJ to Barking
4tph Caledonian Rd to Stratford
and a possible 4tph Caledonian Rd to Dalston "ELL precursor" (what
purpose that would serve, I have no idea - they don't even say whether
that's supposed to be to Kingsland or Junction, and if it's to Junction,
why not just run the proper ELL service?)

Compare that the NR's medium-term proposal; the TfL one offers the
Queen's Park services only as far as Caledonian Road, and offers a
better service on the WLL (4tph exclusive of any Southern services,
rather than inclusive in the NR proposal).
(snip my own post)

Incidentally, NLL services to/from Stratford are diverted to Queen's
Park on a few weekends soon because of engineering work on the rest of
the line.

I went on one of these last time they ran. In the westbound direction,
the train even stopped for a couple of minutes in the (rather
overgrown) platform at Primrose Hill. (I guessed this was part of the
timetable, as recovery time.)

I hope they consider reviving Primrose Hill if frequent services start
running through there, because it would make a more convenient
interchange with the Northern line than any other North London Railway
station would.
